Executive Summary: 

Purpose: 

According to the Environmental Protection Agency (EPA) and water 
utility industry groups, communities will need an estimated $300 
billion to $1 trillion over the next 20 years to repair, replace, or 
upgrade aging drinking water and wastewater facilities; accommodate a 
growing population; and meet new water quality standards. As the agency 
that regulates drinking water and surface water quality, EPA provides a
significant amount of financial assistance for these facilities. Other 
federal agencies, as well as states, also provide assistance. Given the 
magnitude of estimated needs, some industry groups are seeking 
increased federal funding, and the Congress is considering several 
legislative options. 

While drinking water and wastewater utilities use a multitude of funding
sources—including federal and state loans and grants, bonds, and other
debt and equity instruments—they rely primarily on user charges. Indeed,
operating principles established by water utility associations call for 
fully supporting the utilities’ operating and capital costs through 
user and service charges. Utilities that follow these principles derive 
a “cost of providing service” to establish their revenue requirements 
and set their user rates. Depending on the utility, the cost of service 
may include operation and maintenance expenses, taxes (or payments in 
lieu of taxes), depreciation, debt service payments, contributions to 
specified reserves (for example, putting aside funds for future capital 
needs), other capital expenditures, and a rate of return on the value 
of the utility’s assets. According to water utility associations, 
utilities should manage their capital assets to maximize the useful 
life of the assets, control operating costs, and generally enhance the 
efficiency of their operations. Utilities can develop asset management 
plans, which should contain such key elements as an assessment of the 
physical condition of all capital assets, descriptions of the criteria 
used to measure and report on the condition of the assets, information 
on the condition in which the assets will be maintained, and a 
comparison of the planned and actual dollar amounts used to maintain 
the assets at the established condition level. To address financial and 
management challenges, some publicly owned utilities have entered into 
public-private partnerships that use private sector resources in an 
effort to upgrade or replace deteriorating infrastructure or to operate
more efficiently. 

The respective Ranking Minority Members of the Senate Committee on
Environment and Public Works and its Subcommittee on Fisheries, 
Wildlife, and Water, asked GAO to examine several issues relating to the
funding available to help meet the capital investment needs of the 
nation’s drinking water and wastewater facilities. Given the broad 
scope of the request, GAO agreed to provide the information in two 
reports. The first report, issued in November 2001, addressed the 
amounts and sources of federal and state financial assistance for 
drinking water and wastewater infrastructure during fiscal years 1991 
through 2000. [Footnote 1] 

This second report examines (1) how the amount of funds obtained by
large public and private drinking water and wastewater utilities—those
serving populations greater than 10,000—through user charges and other
local funding sources compare with their cost of providing service,
(2) how such utilities manage existing capital assets and plan for 
needed capital improvements, and (3) what factors influence private 
companies’ interest in assuming the operation or ownership of publicly 
owned drinking water and wastewater facilities. To address the first 
and second objectives, GAO mailed questionnaires to 1,425 public and 
private drinking water systems and 2,391 public and private wastewater 
systems, which it identified using EPA databases. In the analysis, 
utilities were weighted to account statistically for all utilities in 
the population, including those not selected in the sample. Overall, 
GAO received responses from an estimated 77 percent of the drinking 
water utilities serving more than 10,000 and 73 percent of the 
wastewater utilities of this size. GAO used the weighted results to 
make estimates about the entire population of drinking water and 
wastewater utilities serving more than 10,000. The percentages cited 
throughout the report are thus estimates and have 95-percent confidence 
intervals of plus or minus 10 percentage points or less. (Copies of the 
questionnaires, including a summary of the utilities’ responses, are
included as appendixes I and II.) To address the third objective, GAO
obtained information from officials with five private companies that 
have significant experience with privatization agreements and are among 
the most active participants in this field, either nationally or 
regionally. In addition, because company officials identified state 
requirements and policies as a significant factor in privatization 
decisions, GAO contacted officials in eight states (California, 
Connecticut, Georgia, Indiana, New Jersey, Pennsylvania, Texas, and 
Washington) that the companies, EPA, and industry associations 
identified as having requirements or policies that could affect 
privatization decisions. 

Background: 

Americans rely on their drinking water and wastewater utilities to 
provide clean and safe water for a variety of uses and to protect 
public health and the environment. Regulated under the Safe Drinking 
Water Act and the Clean Water Act, respectively, community drinking 
water systems and wastewater collection and treatment facilities are 
critical elements in the nation’s infrastructure. Local drinking water 
and wastewater utilities, supported primarily through user charges, 
have invested billions of dollars over the past century in the 
facilities that supply the nation’s drinking water and treat its 
wastewater. In many instances, local communities have received 
financial assistance from federal and state programs. However, even 
with maintenance and repair activities, infrastructure deteriorates 
over time and eventually needs replacement and the estimated needs for
upgrading existing facilities and building new ones are very large, up 
to $1 trillion. 

In response to growing concerns about the condition of the existing 
water infrastructure and calls for increased financial assistance, the 
Congress is considering a number of infrastructure-related proposals. 
At the local level, community leaders are faced with increasing demands 
for funding all types of infrastructure and services and must find new 
ways to control costs or build public support for necessary 
expenditures. Water utility associations, including the Association of 
Metropolitan Sewerage Agencies, the Association of Metropolitan Water 
Agencies, the American Water Works Association, and the Water 
Environment Federation, have established operating principles and 
guidance for managing utilities’ assets and planning for future capital 
needs. In addition, public-private partnerships offer one approach to 
increasing utilities’ operational efficiency. 

Results in Brief: 

According to GAO’s survey, the amount of funds obtained from user 
charges and other local sources of revenue was less than the full cost 
of providing service—including operation and maintenance, debt service,
depreciation, and taxes—for over a quarter of drinking water utilities 
and more than 4 out of 10 wastewater utilities in their most recent 
fiscal year. Revenues from user charges and other local sources were 
adequate to cover at least operation and maintenance costs for nearly 
all of the utilities; however, an estimated 29 percent of the utilities 
deferred maintenance because of insufficient funding. Revenues from 
user charges accounted for most of utilities’ locally generated 
funds—at least three-quarters of all funds from local sources for at 
least three-quarters of utilities. GAO’s survey found that about half 
of the utilities raised their user rates two times or less from 1992 to 
2001. 

GAO’s survey found that more than a quarter of utilities lacked plans
recommended by utility associations for managing their existing capital
assets, but nearly all had plans that identify future capital 
improvement needs. Among the utilities that had plans for managing 
their existing assets, more than half did not cover all their assets or 
omitted key plan elements, such as an assessment of the assets’ 
physical condition. In addition, while most utilities had a preventive 
rehabilitation and replacement program for their pipelines, for about 
60 percent of the drinking water utilities and 65 percent of the 
wastewater utilities, the actual rate of rehabilitation and replacement 
in recent years was less than their desired levels, and many had 
deferred maintenance, capital expenditures, or both. Almost all 
utilities reviewed their future capital improvement needs annually, 
whether or not a formal plan was in place. Many utilities also had 
plans for financing their future capital needs, but nearly half 
believed that their projected funding over the next 5 to 10 years would 
not be sufficient to meet their needs. 

A privatization agreement’s potential to generate profits is the key 
factor influencing decisions by private companies that enter into such
agreements with publicly owned utilities or the governmental entities 
they serve, according to the companies GAO contacted. In assessing 
profit potential, the companies cited several specific criteria, such 
as the extent of opportunities to enhance operational efficiency, the 
utility’s proximity to the companies’ existing operations, the 
potential for system growth, and the potential need for capital 
investments. State policies can also influence privatization 
agreements. For example, two states that GAO contacted restrict the use 
of design-build-operate contracts, which give a single entity complete 
control over a project. Other states offer incentives to encourage the 
takeover of financially troubled public utilities. 

Principal Findings: 

User Charges and Other Local Sources of Funds Covered Much, but Not All,
of Utilities’ Cost of Providing Service: 

GAO found that revenues from user charges exceeded the cost of service
at an estimated 39 percent of the drinking water utilities and 33 
percent of the wastewater utilities. (For the purpose of this analysis, 
GAO defined a utility’s cost of service as operation and maintenance 
expenses, taxes, depreciation, and debt service.) When revenues from 
user charges were combined with funding from other local sources, such 
as hook-up and connection fees and sales of services to other 
utilities, an estimated 71 percent of the drinking water utilities and 
59 percent of the wastewater utilities covered their cost of providing 
service. For both drinking water and wastewater utilities, GAO did not 
find statistically significant differences between utilities by the 
size of the populations they serve; that is, smaller utilities were 
neither more nor less likely than larger utilities to have covered 
their cost of providing service with revenues from user charges and 
other local sources. Similarly, GAO did not find statistically 
significant differences between drinking water utilities by public or 
private ownership. [Footnote 2] 

According to GAO’s survey results, about 85 percent of drinking water
utilities and 82 percent of wastewater utilities covered at least the
operation and maintenance portion of the cost of providing service using
revenues from user charges alone. Moreover, adding other locally
generated funds to the user charges, about 93 percent of the utilities
covered their operation and maintenance costs. Operation and 
maintenance costs are of particular interest because historically,
wastewater utilities—as a condition of receiving certain grants under 
the Clean Water Act—generally were required to cover these costs with 
user charges. While drinking water utilities are not subject to a 
similar requirement, both EPA and water industry associations consider 
adequate user charges to be a key indicator of utilities’ financial 
health. Despite covering operation and maintenance costs, an estimated 
29 percent of the utilities deferred maintenance because of 
insufficient funding. 

GAO found that more than half of utilities whose revenues from user
charges and other local sources did not cover their cost of providing 
service raised their rates two times or less during the 10-year period 
from 1992 to 2001. Overall, GAO found no statistically significant 
differences in the frequency of rate increases between the utilities 
that did not cover their costs and those that did. 

Many Utilities Lacked Comprehensive Asset Management Plans and Had 
Deferred Maintenance or Capital Improvements, but Most Had Identified
Future Capital Needs: 

According to GAO’s survey, a significant percentage of drinking water 
and wastewater utilities—about 27 percent and 31 percent, 
respectively—did not have plans for managing their existing capital 
assets, although some utilities were in the process of developing such 
plans. Further, of the utilities with plans, more than half did not 
include all of their assets or omitted one or more key elements 
recommended by industry associations; for example, 16 percent of 
drinking water utilities’ plans and 21 percent of wastewater utilities’ 
plans did not include information on the condition level at which the 
utility intends to maintain the assets. GAO found no statistical 
differences among utilities of different sizes with regard to the 
inclusion or exclusion of any of the key elements in their asset 
management plans. However, GAO found that the plans developed by 
privately owned drinking water utilities tended to be more comprehensive
than those developed by publicly owned utilities. 

According to GAO’s survey results, some utilities had significant 
portions of pipelines in poor condition; for example, more than one-
third of the utilities had 20 percent or more of their pipelines 
nearing the end of their useful life. Nevertheless, for about 60 
percent of drinking water utilities and 65 percent of wastewater 
utilities, the actual levels of pipeline rehabilitation and replacement 
in recent years were less than the utilities’ desired levels. For 
example, GAO’s survey indicates that roughly half of the utilities 
actually rehabilitated or replaced 1 percent or less of their pipelines 
annually, even though an estimated 89 percent of drinking water 
utilities and 76 percent of wastewater utilities believed that a higher 
level of rehabilitation and replacement should be occurring. Further, 
in each of three categories—maintenance, minor capital improvements, 
and major capital improvements—about one-third or so of the utilities 
had deferred expenditures in their most recent fiscal years, and 20 
percent had deferred expenditures in all three categories. With one 
exception, there were no statistically significant differences among 
utilities of different sizes; however, GAO found that public drinking 
water utilities were more likely than their privately owned 
counterparts to defer maintenance and major capital projects. 

Overall, GAO’s survey results indicate that about 90 percent of drinking
water and wastewater utilities had capital improvement plans to identify
future capital needs, and about 90 percent of utilities reviewed their 
needs annually whether or not they had developed formal plans. About
95 percent of the utilities’ capital improvement plans covered 5 years 
or more—with about 25 percent of drinking water utilities and about
20 percent of wastewater utilities covering 10 years or more. The 
smallest systems (those serving 10,001 to 25,000 people) were slightly 
less likely than larger systems to have such plans. Most of the 
utilities with capital improvement plans also had plans for financing 
the projects they identified; according to GAO’s survey, 86 percent of 
the utilities had such financing plans, including virtually all of the 
largest utilities (those serving populations of over 100,000). However, 
about 45 percent of the drinking water and wastewater utilities 
anticipated that their projected funding would not be sufficient to 
cover future needs over the next 5 to 10 years. Regarding this outlook, 
there were no statistically significant differences among wastewater 
utilities of different sizes; however, the largest drinking water 
utilities were less likely to believe that their projected revenues
would be insufficient to cover anticipated future needs than their 
smaller counterparts. Also, public drinking water utilities were 
somewhat more likely than privately owned systems to have concerns 
about future funding. 

Profit Potential Is Key Factor in Private Companies’ Decisions to 
Assume Operation or Ownership of Drinking Water or Wastewater 
Utilities: 

Privatization agreements range from contracts to operate and maintain
local drinking water or wastewater facilities to outright ownership by
private entities. Not surprisingly, all five of the companies GAO 
contacted evaluate the potential for profits when considering entering 
into privatization agreements. Criteria important to assessing the 
profitability of a proposed utility privatization agreement include the 
potential to improve the efficiency of the utility’s operations; the 
proximity to the company’s other utility operations; the potential for 
system growth; the terms of a proposed contract; and the potential need 
for capital investments. Each of the five companies GAO contacted 
employs a somewhat different business strategy in its pursuit of 
privatization agreements, such as placing more emphasis on contract 
operations rather than assuming ownership of utilities or focusing on 
utilities of particular sizes or in particular locations. Differences 
in the companies’ business strategies had some influence on the 
relative importance of the factors to each company. In addition to 
identifying the site-specific factors they consider in evaluating 
privatization opportunities, representatives from all five companies 
also provided comments on state requirements or policies that can 
facilitate or impede privatization arrangements. 

Officials in eight states GAO contacted said their primary interest is 
the delivery of adequate service to the public, whether the service is 
provided by publicly or privately owned utilities. However, some 
requirements and policies can affect companies’ privatization 
decisions. For example, among the states GAO contacted, state 
regulators in Indiana and Pennsylvania have established programs that 
provide incentives to acquire or take over troubled utilities. In 
Indiana, for example, the acquiring utility is often permitted an 
“acquisition adjustment,” which allows the utility to charge customers 
higher rates. On the other hand, state policies may have the effect of 
limiting privatization; two of the states GAO contacted restrict the 
use of design-build-operate contracts. In Texas, for example, the state
requires the use of qualification-based criteria for selection of 
engineering design services and a bidding process for construction 
services, requirements that effectively preclude combining design, 
construction, and operating services in a single procurement. 

Agency Comments: 

GAO provided a draft of this report to EPA for its review and comment.
GAO received comments from officials in EPA’s Office of Water, including
the Office of Ground Water and Drinking Water and the Office of
Wastewater Management. EPA agreed with the information presented in
the report and characterized the findings as interesting and 
informative. EPA officials also provided several technical comments and 
clarifications, which GAO incorporated as appropriate.

Chapter 1: Introduction: 

Americans rely on their drinking water and wastewater utilities to 
provide clean and safe water for a variety of uses and to protect 
public health and the environment. Regulated under the Safe Drinking 
Water Act and the Clean Water Act, respectively, community drinking 
water systems and wastewater collection and treatment facilities are 
critical elements in the nation’s infrastructure. Local drinking water 
and wastewater utilities, supported primarily through user charges, 
have invested billions of dollars over the past century to create the 
treatment, collection, storage, and distribution facilities that supply 
the nation’s drinking water and treat its wastewater, in accordance 
with applicable federal and state quality standards. In many instances, 
local communities have also received financial assistance from federal 
or state programs to improve or expand their water infrastructure. Even 
with maintenance and repair activities, infrastructure deteriorates 
over time and eventually needs replacement. According to recent 
estimates, the level of investment that will be required over the next 
20 years to repair, replace, or upgrade aging facilities; accommodate 
the nation’s growing population; and meet new quality standards will be 
very large, up to $1 trillion. Moreover, following the terrorist 
attacks of September 11, 2001, both drinking water and wastewater 
utilities may have to make additional investments to increase the 
security of their operations. 

In response to growing concerns about the condition of the existing 
water infrastructure and calls for increased financial assistance, the 
Congress is considering a number of infrastructure-related proposals. 
At the local level, utility managers must find new ways to control 
costs or build public support for increasing the rates charged to 
customers. Among the options available to help local utilities meet the 
challenges they face are ensuring that revenues are adequate to cover 
costs, finding more cost-effective ways to manage utility assets, and 
entering into public-private partnerships. 

Federal, State, and Local Entities Play Important Roles in Ensuring Safe
Drinking Water and Effective Wastewater Treatment: 

The Environmental Protection Agency (EPA) sets standards for the 
quality of drinking water and wastewater and issues other regulations
and guidance to implement the requirements of the Safe Drinking Water 
Act and the Clean Water Act. Under the Safe Drinking Water Act, EPA is 
required to establish (1) standards or treatment techniques for 
contaminants that could adversely affect public health and (2) 
requirements for monitoring the quality of drinking water and for 
ensuring the proper operation and maintenance of water systems. The
Clean Water Act’s National Pollutant Discharge Elimination System
program limits the types and amounts of pollutants that industrial and
municipal wastewater treatment facilities may discharge into the 
nation’s surface waters. EPA has issued national guidance and 
regulations to assist the states in establishing standards to protect 
the quality of their waters and in issuing permits to facilities to 
limit discharges of pollutants. 

Both federal and state agencies also provide a significant amount of
funding for drinking water and wastewater infrastructure through grant
and loan programs. In November 2001, we reported that from fiscal year
1991 through fiscal year 2000, nine federal agencies made available 
about $44 billion for capital improvements at drinking water and 
wastewater systems, and states made available about $25 billion over 
the same period. [Footnote 3] EPA represents the largest source of 
financial assistance at the federal level through its Drinking Water 
and Clean Water State Revolving Funds, contributing about 56 percent of 
the total. Under these programs, EPA provides grants to the states to 
capitalize revolving loan funds. The states, which are required to 
contribute matching funds equal to 20 percent of the EPA grants, make 
loans to local communities or utilities; as loans are repaid, the 
states’ revolving loan funds are replenished. In addition to 
contributing over $10 billion to match EPA’s capitalization grants for 
the Drinking Water and Clean Water State Revolving Funds, the states 
made over $9 billion available under state-sponsored grant and loan 
programs and provided about $6 billion through general obligation and 
revenue bonds and other funding mechanisms. 

At the local level, a variety of public and privately owned utilities 
operate thousands of systems that supply drinking water and treat 
wastewater for millions of Americans. In total, about 55,000 community 
drinking water systems and nearly 30,000 wastewater treatment and 
collection facilities are subject to numerous treatment, testing, and 
operational requirements under the Safe Drinking Water Act and the 
Clean Water Act, respectively. Although many of these utilities are 
quite small, particularly in the case of drinking water systems, 
[Footnote 4] larger utilities serve most of the U.S. population and 
account for most of the infrastructure needs identified in periodic
surveys of such needs conducted by EPA. Specifically, according to EPA’s
Safe Drinking Water Information System, as of January 2001, 4,079
utilities, or about 7 percent of all community water systems, each 
served more than 10,000 people and accounted for about 65 percent of the
estimated infrastructure needs for drinking water utilities. In the 
case of wastewater utilities, about 8,744 treatment and collection 
facilities, or about 29 percent of the total, are estimated to serve 
more than 10,000 people. These facilities account for approximately 89 
percent of the estimated infrastructure needs for wastewater utilities. 
[Footnote 5] 

Publicly owned drinking water and wastewater utilities include systems
owned by municipalities, townships, counties, water and/or sewer 
districts, and water and/or sewer authorities. Private ownership 
encompasses a broad range of owners, from homeowners’ associations,
mobile home parks, and other entities whose primary business is 
unrelated to water supply or wastewater treatment, to larger, investor-
owned companies. About half of the nation’s drinking water systems and
an estimated 20 percent of the wastewater systems are privately owned,
according to EPA and industry sources. According to EPA, most of the
privately owned drinking water and wastewater systems serve populations
of less than 10,000. 

Addressing Future Drinking Water and Wastewater Infrastructure Needs 
Will Require Major Investments: 

EPA and a variety of industry groups are predicting that major 
investments will be needed to upgrade, repair, or replace existing 
infrastructure; meet demands for additional capacity; or comply with 
new regulatory requirements. Pipeline rehabilitation and replacement 
represents a significant portion of the projected infrastructure needs. 
According to EPA estimates, for example, at least half of the drinking 
water and wastewater infrastructure need is in the form of pipes buried 
under ground. A study sponsored by a major water industry association 
concluded that much of the existing pipe network is at or near the end 
of its expected lifespan. [Footnote 6] Using average life estimates for 
different types of pipe and counting the years since the lines were 
originally installed, the study predicts that drinking water utilities 
will face significant repair and replacement costs over the next 3 
decades. Other studies make similar predictions for the pipelines owned 
by wastewater utilities. [Footnote 7] Figure 1 shows the estimated life 
expectancy of the pipelines installed during major periods of utility 
growth.

While the size, period covered, and specific assumptions of individual
estimates vary, the amount needed for future capital investments in 
water and wastewater infrastructure will be substantial. Several recent 
studies project future infrastructure needs over a 20-year period: 

* According to EPA’s 1999 survey of drinking water infrastructure 
needs, the estimated needs would be at least $150.9 billion through 
2019, including an estimated $83.2 billion just for water transmission 
and distribution lines. [Footnote 8] 

* Similarly, EPA’s 1996 survey of “clean water” needs estimated that 
total wastewater infrastructure-related needs will be about $128 
billion through 2016. [Footnote 9] In a subsequent analysis, EPA 
estimated that an additional $56 billion to $87 billion would be needed 
to correct existing sanitary sewer overflow problems. 

* In April 2000, the Water Infrastructure Network, a consortium of 
industry, municipal, state, and nonprofit associations, projected needs 
of up to 1 trillion dollars over the next 20 years for drinking water 
and wastewater utilities combined, when both the capital investment 
needs and the cost of financing are considered. [Footnote 10] 

* In May 2002, the Congressional Budget Office estimated that the cost 
of drinking water and wastewater infrastructure over the next 20 years
would be $492 billion under a low-cost scenario and $820 billion under a
high-cost scenario, including both the cost of physical capital and 
interest on loans and bonds. [Footnote 11] 

Whatever the level of investment turns out to be, the needs will be 
likely be met by some combination of local, state, and federal funding 
sources. As the Congressional Budget Office noted in its recent report, 
society as a whole will ultimately foot the bill, whether through the 
rates charged to users or through federal, state, or local taxes. 

Adequacy of User Charges Is Key Indicator of Sound Management at
Drinking Water and Wastewater Utilities: 

Drinking water and wastewater utilities need revenue to maintain current
service levels, meet new demands for service, adequately maintain 
existing plant and equipment, and plan for future needs in an orderly 
manner. To accomplish these goals, water industry associations 
generally support the principle that utilities should generate enough 
revenue through user rates and service charges to fully cover the cost 
of providing service, without relying on subsidies from other revenue 
sources. [Footnote 12] That is, the rates that utilities charge their 
customers should be sufficient to finance all of the utilities’ 
operating and maintenance expenses as well as capital costs. For 
example, according to a group of water industry associations known as 
the H2O Coalition, water utilities should move toward becoming self-
sustaining by charging their customers rates that reflect the full cost 
of service, thus ensuring that utilities will get as much of the 
revenues they need as possible from their customers. [Footnote 13] 
EPA’s Office of Water also supports the concept of fiscal 
sustainability for water utilities and sees rates that result in 
revenues sufficient to meet the cost of service as a measure of the 
utilities’ financial health. 

In some instances, drinking water and wastewater utilities may have to
establish user rates that meet certain minimum requirements as a
condition of receiving federal or state financial assistance. For 
example, the Clean Water Act requires wastewater utilities that received
construction grants under title II of the act to establish rates that 
generate enough revenue to cover operation and maintenance costs. Less 
specific requirements apply to wastewater utilities that receive loans 
under the Clean Water State Revolving Fund Program. Although the Safe 
Drinking Water Act does not contain any explicit requirements for 
minimum user charges at drinking water utilities, EPA has addressed the 
issue indirectly in guidance to the states. Under the Safe Drinking 
Water Act Amendments of 1996, states are required to develop programs 
to ensure that drinking water systems have the financial, managerial, 
and technical capacity to comply with national drinking water 
regulations. EPA’s guidance on implementing such programs suggests that 
the criteria for assessing the systems’ financial capacity include a 
determination of whether water rates and charges are adequate to cover 
the cost of water. [Footnote 14] 

Utilities Use Approaches Such as Asset Management and Privatization to
Increase Operational Efficiency: 

In addition to maintaining adequate user charges, utilities can ensure 
that their revenues are sufficient by increasing their operational 
efficiency and thus controlling their costs. One approach recommended 
by industry experts is “asset management.” The goal of asset management 
is to manage infrastructure assets so that the total cost of owning and 
operating them is minimized and desired customer service levels are 
maintained. The asset management process involves assessing the 
condition of a system’s infrastructure assets, estimating the life 
expectancy of these assets, and ensuring that sufficient funds are 
allocated over the life of the assets to optimize their value. 

Asset management is seen as particularly relevant to the water utility
industry because drinking water and wastewater utilities are capital-
intensive and have a sizeable investment in pipes and other assets with 
a relatively long service life. According to a comprehensive industry
handbook on managing capital assets, there is a growing awareness among
water utilities that “preserving the life and function of 
infrastructure assets will help optimize operations and maintenance and 
identify needed capital resources, thereby reducing funding gaps 
between future capital needs and available financial resources.” 
[Footnote 15] Given the magnitude of the estimates for future 
infrastructure needs, it is important for utilities to adopt a strategy 
for managing the repair and replacement of key assets as cost-
effectively as possible. 

In recent years, privatization of public facilities and services, 
particularly at drinking water utilities, has been occurring in the 
United States at an increasing rate. Some municipal drinking water and 
wastewater utilities have explored privatization as another option for 
increasing operational efficiency. Privatization is commonly defined as 
any process aimed at shifting functions and responsibilities, in whole 
or in part, from the municipal government to the private sector. 
Municipalities may turn to privatization agreements to address issues 
such as needed infrastructure improvements, rising costs, or more 
stringent regulatory requirements. 

Privatization can take different forms, ranging from contracting for
specific services to the actual sale of a facility to a private 
company. The most common form of privatization is contracting, which 
typically entails a competition among private bidders to perform 
certain activities. In the case of drinking water and wastewater 
utilities, such activities typically include operation and maintenance. 
When a municipality contracts with a private company for services, the 
government remains the financier and has management and policy control 
over the quality of services to be provided. In some instances, 
privatization involves the transfer of the ownership of utility assets 
from a municipality to the private sector. Once the assets have been 
sold, the government generally has no role in their financial support, 
management, or oversight. 

Objectives, Scope, and Methodology: 

The Ranking Minority Member, Senate Committee on Environment and Public 
Works, and the Ranking Minority Member, Subcommittee on Fisheries, 
Wildlife, and Water, Senate Committee on Environment and Public Works, 
asked us to examine several issues relating to the funding available to 
help meet the capital investment needs of the nation’s drinking water 
and wastewater facilities. [Footnote 16] This report provides 
information on: 

* how the amount of funds obtained by large public and private drinking
water and wastewater utilities—those serving populations greater than
10,000—through user charges and other local funding sources compare
with the cost of providing service; 

* how such utilities manage existing capital assets and plan for needed
capital improvements, and; 

* what factors influence private companies’ interest in assuming the
operation or ownership of publicly owned drinking water and wastewater
facilities. 

To address the first two objectives, we obtained information on utility
finances and capital management practices by surveying, using a mailed
questionnaire, drinking water and wastewater utilities that serve 
populations greater than 10,000. We developed similar but separate
questionnaires, one for drinking water utilities and one for wastewater
utilities. We focused on utilities serving populations of more than 
10,000 because they (1) accounted for a large share of infrastructure 
needs and (2) were more likely than their smaller counterparts to have 
the means to respond to our survey. A copy of the drinking water 
utility questionnaire, with summary response data, is in appendix I, 
and a copy of the wastewater utility questionnaire, with summary 
response data, is in appendix II. 

We obtained contact information for the drinking water utilities from
EPA’s Safe Drinking Water Information System database. We mailed
questionnaires to all 480 private drinking water utilities and to a 
sample of 945 public drinking water systems, stratified by size of 
population served (the size categories appear on the questionnaires), 
identified in the database. (Thus, we sent questionnaires to a total of 
1,425 utilities.) We obtained contact information for the public and 
private wastewater utilities from EPA’s Clean Water Needs Survey 
database and EPA’s Permit Compliance System database. [Footnote 17] EPA 
does not collect information specifically on the size of the population 
served by wastewater utilities. However, EPA officials estimate that 
facilities that process more than 1 million gallons of wastewater per 
day are roughly equivalent to facilities that serve populations of more 
than 10,000 people. Thus, we used EPA’s data on plant capacity to 
approximate the sizes of wastewater utilities. We then mailed 
questionnaires to all 2,391 of the systems estimated on this basis to 
serve populations greater than 10,000. 

We included on the questionnaires a “screening” question to make certain
that the responses we obtained and used were in fact from utilities that
served populations greater than 10,000. We obtained 821 useable
responses from drinking water utilities and 1,113 useable responses from
wastewater utilities. In the analysis, utilities were weighted to 
account statistically for all utilities serving populations greater 
than 10,000, including those not selected for our sample. Overall, 
using response data from the screening question and from nonrespondent 
follow-up efforts to adjust the estimated number of drinking water and 
wastewater utilities serving populations greater than 10,000, we 
estimate that 77 percent of the drinking water utilities serving more 
than 10,000 people and 73 percent of the wastewater utilities of this 
size responded to the survey. We used the weighted results to make 
estimates about the entire population of such drinking water and 
wastewater utilities. Therefore, all utility percentages cited in the 
remainder of the report are estimates and have some sampling error 
associated with them. All estimates cited have 95-percent confidence 
intervals of plus or minus 10 percentage points or less; that is, we are
95 percent confident that the “actual” population value is contained in 
an interval of 10 percentage points above or below the estimate. We used
these sampling errors to assess statistically significant differences
between percentages as well. 

In addition to sampling errors, surveys can be subject to other types of
systematic error or bias that can affect the results, commonly referred 
to as nonsampling errors. For example, questions may be misinterpreted; 
the respondents, as a group, may differ from those who did not respond 
in ways that are important; or response data could be erroneously
transcribed or entered into a database. We took several steps in an 
attempt to reduce such errors. For example, to minimize the chances of 
questions being misinterpreted, we developed our survey questions with 
the aid of a survey specialist. We discussed the questionnaire with 
officials from the EPA’s Office of Water; the Association of 
Metropolitan Sewerage Agencies; the American Water Works Association; 
the Water Environment Federation; three consulting firms that 
specialize in the water utility industry: Beecher Policy Research, 
Inc., Hayden Reynolds & Associates, Pty. Ltd., and PA Consulting Group; 
and public utility commissions in the states of West Virginia and 
Wisconsin. In addition, we pretested the questionnaires with five 
drinking water utilities and five wastewater utilities. [Footnote 18] 
To maximize our response rate, we sent reminder postcards and mailed 
two follow-up questionnaires to all nonrespondents. All data were
double keyed during data entry, and we verified a sample of the 
resulting automated data. We ran various edit checks and other computer 
analyses to identify inconsistencies and potential errors in the data, 
and a technical specialist independently reviewed all computer programs.
One of our objectives was to compare public and privately owned 
utilities. However, we did not receive enough responses from privately 
owned wastewater utilities for a meaningful analysis (as noted 
previously, according to EPA, most privately owned wastewater systems 
serve populations of less than 10,000 people). Therefore, our analyses
concerning utility ownership type were limited to drinking water 
utilities only. In comparing utilities according to the size of the 
population served, we collapsed the size categories into four: 
utilities serving populations of 10,001 to 25,000; 25,001 to 50,000; 
50,001 to 100,000; and over 100,000. 

To address the third objective, we interviewed officials from five 
private companies that have significant experience with privatization 
agreements and are among the most active participants in this field 
either nationally or regionally. The companies are American Water Works 
Service Company, Inc., United States Filter Corporation, and United 
Water (companies that operate nationally in a total of 40 states); ECO 
Resources, Inc., which operates principally in the Southwest; and 
Philadelphia Suburban Water Company, which focuses its operations in 
the mid-Atlantic and Midwest. In addition, because company officials 
identified state requirements and policies as a significant factor in 
their investment decisions, we interviewed officials from eight states 
(California, Connecticut, Georgia, Indiana, New Jersey, Pennsylvania, 
Texas, and Washington) that the companies, EPA, or industry officials 
identified as having requirements or policies that could affect 
privatization. 

We conducted our work between May 2001 and July 2002 in accordance
with generally accepted government audit standards. 

[End of chapter] 

Chapter 2: User Charges and Other Local Sources of Funds Covered Much, 
but Not All, of Utilities’ Cost of Providing Service: 

According to our survey, the amount of funds obtained from user charges
and other local sources of revenue was less than the full cost of 
providing service—including operation and maintenance, debt service, 
depreciation, and taxes—for an estimated 29 percent of drinking water 
utilities and 41 percent of wastewater utilities. (Our survey requested 
information on utilities’ revenues and costs during their most recently 
completed fiscal year.) Revenues from user charges and other local 
sources were adequate to cover at least operation and maintenance costs 
for over 93 percent of the utilities, but about 29 percent of the 
utilities deferred maintenance during the same time period because of 
insufficient funding. Revenues from user charges usually accounted for 
most of utilities’ locally generated funds. Our survey found that about 
half of the utilities raised their user rates infrequently—once, twice, 
or not at all—from 1992 to 2001. 

Funds Collected from Local Sources Were Often Less Than Utilities’ Cost 
of Providing Service: 

We found that revenues from user charges and other local sources often
fell short of utilities’ cost of providing service, as defined below. 
According to EPA and major water industry associations, in order to be 
self-sustaining, drinking water and wastewater utilities must recover 
the full cost of providing service through their user rates and service 
charges. Rates that generate sufficient revenue to cover the full cost 
of service lessen the need for external assistance, such as federal or 
state grants and loans. Determining the cost of service establishes a 
utility’s revenue requirements and, accordingly, can serve as a basis 
for its rate structure. 

According to the National Regulatory Research Institute, “determining
utility revenue requirements involves an examination of aggregate annual
costs, including operating as well as capital costs,” to derive the 
utility’s cost of providing service. [Footnote 19] In a November 1993 
report, the Institute explained that water utilities generally use one 
of two basic methods of determining their revenue requirements for the 
purpose of setting user rates, largely depending on whether the utility 
is public or privately owned: [Footnote 20] 

* Under the “utility” approach, which is typically used by investor or
privately owned utilities, the total cost of service includes operation 
and maintenance expenses, taxes, depreciation, and a rate of return on 
the value of the utilities’ assets less accumulated depreciation. 

* Under the “cash needs” approach, used by many public utilities, the 
total cost of service includes operation and maintenance expenses, tax
equivalents (e.g., payments in lieu of taxes), debt service payments
(including both interest charges and repayment of principal),
contributions to specified reserves, and capital expenditures not 
financed by either debt or contributions. 

To determine whether revenues from user charges and other local sources
were large enough to cover the cost of providing service among the
utilities covered by our survey, we adapted the utility approach. We
developed a modified utility method because it allowed us to (1) adopt a
standard approach to deriving the “cost of providing service” for both
public and privately owned utilities, thereby enabling more meaningful
summaries and comparisons among all of the utilities and (2) make the
most effective use of the categories of cost data we collected. 
Specifically, to calculate the cost of service, we included the amounts 
reported for operation and maintenance expenses, taxes, and 
depreciation. [Footnote 21] We also included the amounts reported as 
debt service (including interest charges and repayment of principal) as 
a surrogate for rate of return, a category for which our survey did not 
request information. [Footnote 22] Because of the approach we used, we 
may have overstated some utilities’ costs and thus the number of 
utilities that did not cover their costs. The reason is that for some 
utilities the portion of debt service attributable to repayment of
principal may have been covered, in part, by the inclusion of 
depreciation in computing the cost of service. 

User Charges Represent One of Many Sources of Funding Used by 
Utilities: 

Our survey showed that virtually all utilities obtained revenues from 
user charges during their most recently completed fiscal year. Other 
common funding sources included hook-up and connection fees and interest
earnings, used by an estimated 80 to 90 percent of utilities. Table 1
summarizes the types of funding used by drinking water and wastewater
utilities during their most recently completed fiscal year, according 
to our survey.

for the large percentage of such utilities that used the Other category 
under the Other local revenues category (51 percent compared to 29 
percent of wastewater utilities).

User Charges and Other Local Revenues Were Less Than Many Utilities’ 
Cost of Providing Service: 

Using the modified utility approach described earlier, we analyzed our
survey data to compare utilities’ costs and revenues. Among other 
things, we found that for many utilities, revenues from user charges 
alone were not enough to cover the cost of service in their most 
recently completed fiscal year. Specifically, we found that revenues 
from user charges exceeded the cost of service at an estimated 39 
percent of the drinking water utilities and 33 percent of the 
wastewater utilities. However, combining revenues from user charges 
with funding from other local sources, such as hook-up and connection 
fees and sales of services to other utilities, we found that more 
utilities were able to cover their cost of providing service. 
Specifically, for an estimated 71 percent of the drinking water 
utilities and 59 percent of the wastewater utilities, user charges plus
other local revenues exceeded the cost of providing service. 

We analyzed our survey data to determine if there were any statistically
significant relationships between certain utility characteristics and 
the utilities’ ability to cover costs with user charges and/or other 
local revenues. First, we examined these relationships for both (1) the 
size of the population served by the utilities and (2) the type of 
ownership (public or private). We found the following: 

* For both drinking water and wastewater utilities, there were no
statistically significant differences between utilities based on the 
size of the populations they served; that is, smaller utilities were 
neither more nor less likely than larger utilities to have covered 
their cost of providing service, whether we looked at revenues from 
user charges alone or revenues from all local sources. 

* Among drinking water utilities, ownership type did make a difference
when comparing the cost of providing service with revenue from user
charges alone. We found that 62 percent of public drinking water 
utilities did not cover their cost of service with user charges alone, 
compared with 44 percent of privately owned systems. However, when we 
included revenues from other local sources in the analysis, we found no 
statistical difference between public and privately owned drinking 
water utilities. 

EPA has reached similar conclusions about the ability of some utilities 
to cover their costs. For example, in a July 1999 report on the 
characteristics of small drinking water systems, defined as those 
serving less than 10,000 people, EPA compared such systems to larger 
ones serving more than 10,000 people—the same group included in our 
study. EPA reported that an estimated 20 percent of the larger systems 
did not have sufficient revenues to cover their debt service costs 
after paying operating expenses. [Footnote 23] In the case of 
wastewater utilities, a September 1990 study on user fees reported that 
when total wastewater revenues were compared to total wastewater 
treatment costs, a significant percentage of the utilities included in 
the study—31 percent of those serving populations of 10,000 to 100,000 
and 26 percent of those serving over 100,000 people—were operating with 
a revenue shortfall. [Footnote 24] As defined in the study, total 
treatment costs consisted of debt repayment costs plus operation, 
maintenance, and equipment replacement costs. 

We next analyzed our survey data to determine if there were any
statistically significant relationships between utilities’ ability to 
cover costs with user charges and/or other local revenues and other
characteristics. Overall, we found few significant differences; that 
is, for the most part, utilities that covered their cost of providing 
service with revenues from user charges and/or other local sources did 
not differ—on the basis of characteristics we examined—from those that 
did not. More specifically, we found the following regarding utilities’ 
ability to cover their cost of providing service with user charges and 
other local revenues and the following characteristics: 

* Use of federal or state grants or loans. An estimated 24 percent of 
the drinking water utilities and 36 percent of the wastewater utilities 
that did not cover their costs obtained federal and/or state grants 
during their most recently completed fiscal year. These utilities 
obtained grants at about the same rate as the drinking water and 
wastewater utilities that did cover their costs. Similarly, when we 
included utilities that received federal or state loans in our 
analysis—in addition to the utilities that received assistance from 
grants—we found that an estimated 43 percent of the drinking water 
utilities and 60 percent of the wastewater utilities that did not cover 
their costs used some form of federal or state grant or loan. These 
utilities received assistance at about the same rate as utilities that
did cover their costs. 

* Dedication of rate revenues for specific purposes. We found no 
statistical differences regarding the extent to which utilities’ rates 
included amounts to cover the cost of preventive rehabilitation and 
replacement programs for pipelines. Based on our survey, an estimated 
85 percent of the utilities’ rates included such amounts, whether or 
not the utilities covered their cost of providing service. Similarly, 
both drinking water and wastewater utilities that covered their cost of 
service were no more likely than those that did not to dedicate a 
portion of revenues from user charges specifically to future capital 
needs. Overall, according to our survey, about 70 percent of drinking 
water and wastewater utilities dedicated a portion of their user 
charges to future capital needs in developing their rates. 

* Existence of rate relief or other subsidy for lower-income customers.
About the same percentage of utilities offered some type of subsidy to
lower-income customers—about 14 percent of the drinking water utilities
and about 13 percent of the wastewater utilities—whether or not the
utilities covered their cost of service. 

More comprehensive information might have allowed us to draw some
clearer distinctions between utilities that did and did not cover their 
costs. However, to limit the burden on our survey respondents, we did 
not ask utilities to report the amount of any assistance they received, 
and we requested data on only the most recently completed fiscal year. 

Funds from Local Sources Generally Exceeded Operation and Maintenance 
Costs: 

Annual operation and maintenance costs are those associated with 
operating and maintaining a utility—including the costs of labor, 
energy, chemicals, and accounting services. Operation and maintenance 
costs are of particular interest because of certain requirements 
imposed on many wastewater utilities as a condition of receiving 
construction grants under the Clean Water Act. Specifically, the 
wastewater utilities are required to generate sufficient revenues 
through user charges to cover operation and maintenance costs. 
[Footnote 25] According to EPA’s 1990 report on wastewater user fees, 
all wastewater utilities serving more than 10,000 people at that time 
received such grants. [Footnote 26] While drinking water utilities are 
not subject to a similar requirement, both EPA and key water industry 
associations consider adequate user charges to be a key indicator of 
utilities’ financial health. 

According to our survey results, an estimated 85 percent of drinking 
water utilities and 82 percent of wastewater utilities were able to 
cover their operation and maintenance costs using revenues from user 
charges alone. Moreover, adding other locally generated funds to the 
user charges, we estimated that over 93 percent of the utilities were 
able to cover their operation and maintenance costs. With one 
exception, we also found that a utility’s size or type of ownership did 
not influence its ability to cover operation and maintenance costs. 
However, privately owned drinking water utilities were somewhat more 
likely to have sufficient revenues from user charges to cover their 
operation and maintenance costs than public utilities (the estimates 
were 91 percent compared to 85 percent). 

Our findings are consistent with EPA’s July 1999 report on the 
characteristics of small drinking water systems, which compared systems 
serving less than 10,000 people to systems serving more than 10,000 
people. EPA reported that 13 percent of the larger systems (those 
serving populations of more than 10,000) had operation and maintenance
expenses that exceeded their operating revenues. [Footnote 27] For the 
purposes of its study, EPA defined operating revenues as the sum of 
water sales and the following water-related revenues: connection fees, 
inspection fees, developer fees, usage fees, other fees, and general 
fund revenues. Interest earned, primary business revenues, fines or 
penalties, and other water related revenues were not included. Although 
our results indicate that a smaller percentage of utilities were not 
covering their costs than EPA’s study concluded, we defined local 
sources of revenue more broadly than EPA and included some categories, 
such as interest earnings and reserve payments, that were used by large 
percentages of utilities. EPA has not done a similar analysis of 
wastewater utilities. 

While our survey shows that, for an overwhelming majority of utilities,
locally generated funds met or exceeded their operation and maintenance
costs, it provides some indications that utilities’ costs may be lower 
than they should be to adequately maintain facilities and equipment.
Specifically, we looked at the extent to which utilities that were 
covering their operation and maintenance costs also deferred maintenance
“because available funding was not sufficient.” We found that for both
drinking water and wastewater utilities, an estimated 29 percent of the
utilities that covered their costs also deferred maintenance in their 
most recently completed fiscal year. However, there was no statistical
difference in the extent to which the utilities deferred maintenance,
whether they covered their operation and maintenance costs or not. 

The fact that utilities were deferring maintenance suggests that either
unanticipated expenses forced the utilities to reschedule planned
maintenance or their budgets were never sufficient to cover the needed
expenses in the first place. According to EPA and water industry 
experts, deferring maintenance beyond the optimal point for system 
repair and renewal can lead to earlier capital replacement needs and 
increases in the cost of providing service. 

User Charges Represented a Major Source of Local Funds, but Were 
Increased Two Times or Fewer by Half of the Utilities: 

User charges represent a major source of locally generated funding at 
both drinking water and wastewater utilities. According to our survey, 
for about half of the utilities, user charges accounted for at least 90 
percent of their local funds in their most recently completed fiscal 
year. [Footnote 28] User charges accounted for at least three-quarters 
of the funds from local sources at an estimated 80 percent of the 
drinking water utilities and about 75 percent of the wastewater 
utilities. 

We analyzed the data on utilities’ user charges to determine if the 
utilities’ ability to cover their cost of providing service was related 
to the frequency of their rate increases. As noted earlier, our survey-
based estimates are that 29 percent of drinking water utilities and 41 
percent of wastewater utilities had revenues from user charges and 
other local sources that were less than their cost of providing 
service. As table 2 shows, we found that more than half of these 
utilities reported raising their rates infrequently—once, twice, or not 
at all—during the 10-year period from 1992 to 2001. However, overall we 
found no statistically significant differences in the frequency of rate 
increases between the utilities that did not cover their costs and 
those that did. 

We did not ask utilities to provide information on the magnitude of 
their rate increases. Some utilities may have a strategy of seeking 
fewer but larger rate increases. This strategy could enable them to 
cover more of their costs if the rate increases, though infrequent, are 
sufficiently large.

Utilities’ Ability to Cover Their Cost of Providing Service Using 
Revenues from All Local Sources, 1992–2001:

Other studies provide some data on the magnitude and frequency of rate
increases by water utilities. In its July 1999 report on the 
characteristics of small drinking water systems, EPA examined the 
frequency and magnitude of rate increases and found that for larger 
systems (those serving more than 10,000 people), about 2-½ years had 
elapsed, on average, since the last increase. [Footnote 29] In 
addition, EPA reported that the average size of the increase was 14 
percent. Similarly, data collected by the Association of Metropolitan 
Sewerage Agencies for its 1999 financial survey indicated that the 
current rates had been in effect for an average of about 2-½ years.
This survey also found that the sewer rates had increased 9 percent
annually, on average, between 1996 and 1999. [Footnote 30] 

We further analyzed our survey data to determine if the frequency of 
rate increases varied depending on the utilities’ size. We found that 
larger utilities, particularly those serving more than 100,000 people, 
were more likely to have had 5 to 10 rate increases from 1992 to 2001 
than smaller utilities. Conversely, smaller utilities were more likely 
than larger ones to have increased their rates infrequently during the 
10-year period. Table 3 summarizes the results of our analysis.

Chapter 3: Many Utilities Lacked Comprehensive Asset Management Plans, 
but Most Had Identified Future Capital Needs: 

According to our survey, more than one out of four utilities lacked 
plans recommended by utility associations for managing their existing 
capital assets. Further, over half of the utilities with plans did not 
cover all their assets or omitted key plan elements, such as an 
assessment of the assets’ physical condition. In addition, while most 
utilities had a preventive rehabilitation and replacement program, for 
about 60 percent of the drinking water utilities and 65 percent of the 
wastewater utilities, the actual rate of pipeline rehabilitation and 
replacement in recent years was less than their desired levels. 
Further, in their most recent fiscal year, an estimated one-third of 
the utilities deferred maintenance; one-third deferred major capital 
improvements; and one-third deferred minor capital improvements. 

Our survey indicates that about 90 percent of the utilities had capital
improvement plans that identify future needs and that about the same
percentage of utilities reviewed their capital improvement needs 
annually whether or not a formal plan was in place. Utilities’ capital 
improvement plans generally had a long-term focus—the large majority 
covered 5 years or more—as recommended by industry associations. Most 
utilities also had plans for financing their future capital needs, but 
an estimated 45 percent believed that their projected funding over the 
next 5 to 10 years would not be sufficient to meet the needs. 

Many Utilities Lacked Comprehensive Asset Management Plans: 

According to our survey, more than 25 percent of drinking water and 
wastewater utilities lacked asset management plans, although some were
in the process of developing such plans. Of the utilities with plans, 
more than half did not include all of their assets or omitted key plan 
elements. 

Drinking water and wastewater utilities manage their existing capital
assets to maximize the useful life of the assets, control operating 
costs, and generally enhance the efficiency of their operations. 
According to a comprehensive industry handbook, published in 2001, the 
term “asset management” means managing infrastructure-related assets, 
such as pipelines and equipment, to minimize the total cost of owning 
and operating them while maintaining adequate service to customers. 
[Footnote 31] The handbook states that asset management allows an 
organization to characterize the condition of capital assets and 
quantify an ongoing renewal program to maximize their reliability. The 
handbook further provides that a goal of an asset management system 
should be “the ability to merge what is known about an organization’s 
capital assets with rehabilitation standards and costs and with risk 
assessments of asset failures to identify critical assets.” [Footnote 
32] 

For the purposes of our survey, we focused on four areas identified as 
key elements of good asset management systems: an inventory of the 
assets, assessment criteria, the assets’ condition, and the planned and 
actual expenditures to maintain the assets. [Footnote 33] More 
specifically, we asked drinking water and wastewater utilities (1) if 
they had plans for managing their existing capital assets and (2) if 
so, whether these plans included a complete assessment of the physical 
condition of all capital assets, descriptions of the criteria used to 
measure and report on the condition of the assets, the condition level 
at which the assets will be maintained, and a comparison of the planned 
and actual dollar amounts used to maintain the assets at the 
established condition level. For each of the key elements, we also 
asked if the plans covered all or some capital assets or did not 
address the element at all. 

Some Utilities Did Not Have Plans: 

Based on the results of our survey, a significant percentage of drinking
water and wastewater utilities—an estimated 27 percent and 31 percent,
respectively—did not have plans for managing their existing capital 
assets. However, 40 percent of the drinking water utilities and about 
50 percent of the wastewater utilities were developing such plans at 
the time of our survey. 

When we looked at the characteristics of the utilities without asset
management plans, for the most part, we found no statistical differences
between utilities of different sizes for either drinking water or 
wastewater utilities, with one exception: about twice as many of the 
smallest drinking water utilities—those serving populations of 10,001 
to 25,000—lacked plans compared with the largest ones, serving 
populations of over 100,000 (the estimates were 34 percent and 17 
percent, respectively). We also found that public drinking water 
utilities were somewhat more likely than their privately owned 
counterparts not to have plans for managing their existing capital 
assets (an estimated 29 percent compared with 11 percent). 

Many Utilities’ Plans Did Not Cover All Assets or Lacked Key Elements: 

According to our survey, more than two-thirds of the utilities had asset
management plans—an estimated 69 percent of the drinking water utilities
and 65 percent of the wastewater utilities—but many of the plans did not
cover all of the utilities’ assets or did not contain one or more key
elements. [Footnote 34] Table 4 summarizes the extent of coverage of 
utilities’ assets and the four key elements in utilities’ asset 
management plans.

[End of table] 

Significantly, our survey results indicate that over 50 percent of 
utilities’ asset management plans did not cover all assets. Industry 
associations for both drinking water and wastewater utilities advocate 
the inclusion of all capital assets in such plans. They also believe 
that good asset management planning starts with a comprehensive 
inventory of existing assets and encompasses other elements addressed 
in our survey as well. In fact, the comprehensive industry handbook 
cited earlier indicates that an integrated asset management system 
includes, among other things, a maintenance management system as well 
as components designed to inventory and analyze the condition of a 
utility’s assets. [Footnote 35] Using this information, utilities can 
optimize decisions on what system components require maintenance or 
need to be rehabilitated or replaced, when these actions need to occur, 
and what they will cost. 

To minimize the reporting burden on utilities, we did not ask the 
surveyed utilities to be more explicit about the types of assets that 
were or were not covered by the plans. However, some evidence suggests 
that utilities might not be developing comprehensive plans for the 
management of their pipelines, a potentially critical omission 
considering that pipelines account for about 75 percent of the nation’s 
investment in drinking water and wastewater infrastructure. A study 
sponsored by the American Water Works Association Research Foundation 
concluded that effective planning for pipeline rehabilitation and 
replacement falls into three categories: 

(1) developing asset inventory data on pipe condition by segment; (2) 
developing priorities for annual replacement plans, and; (3) developing
long-term plans to optimize the rate of replacement. [Footnote 36] 
However, the report states that 15 of the 18 utilities reviewed for the 
study had not developed comprehensive information projecting their 
pipeline replacement needs based on when the pipes were installed and 
how long they are expected to last. 

For utilities with plans, we analyzed our survey data according to the 
size of the utility. We found no statistical differences among 
utilities of different sizes with regard to the inclusion or exclusion 
of any of the four key elements in their asset management plans. 
However, when we similarly analyzed the data according to the type of 
utility ownership, we found that the asset management plans developed 
by privately owned drinking water utilities tended to be more 
comprehensive than those developed by publicly owned utilities. For 
example, we found that an estimated: 

* 55 percent of private utilities’ plans covered all capital assets, 
compared with 40 percent of public utilities; 

* 46 percent of private utilities’ plans included criteria for all 
assets, compared with 28 percent for public utilities; 

* 43 percent of private utilities’ plans included the condition level 
at which the assets would be maintained, compared with 33 percent for 
public utilities; and; 

* 40 percent of private utilities’ plans included a comparison of the 
planned and actual expenditures for maintaining the assets, compared 
with 26 percent for public utilities. 

Despite Pipelines in Poor Condition, Some Utilities Had Deferred 
Maintenance, Capital Improvements, or Both: 

According to our survey results, some utilities had significant 
portions of pipelines in poor condition; for example, more than one-
third of utilities had 20 percent or more of their pipelines nearing 
the end of their useful life. We also found that for an estimated 60 
percent of drinking water utilities and 65 percent of wastewater 
utilities, the actual levels of pipeline rehabilitation and replacement 
in recent years were less than the utilities’ desired levels. Further, 
in each of three categories—maintenance, minor capital improvements, 
and major capital improvements—an estimated one-third or so of 
utilities had deferred expenditures in their most recent fiscal year, 
and 20 percent had deferred expenditures in all three categories. 

Drinking water and wastewater utilities carry out various activities to
ensure efficient and cost-effective operations and plan for needed 
improvements. According to the industry handbook, for example, utilities
carry out planned maintenance of plant, equipment, and pipes to prevent,
minimize, or delay failures or shutdowns that result in unplanned 
maintenance activities and increased costs. [Footnote 37] Utility 
officials told us that they also rehabilitate existing assets, such as 
pipelines, to extend their useful life. Both regular maintenance and 
rehabilitation of key assets help utilities keep their operating costs 
as low as possible. When maintenance and asset rehabilitation are no 
longer cost-effective options and capital assets reach the end of their 
useful life, they must be replaced, often requiring large investments. 
Despite their needs, utilities may have to postpone capital 
improvements because revenues are not sufficient to finance the costs 
or more immediate needs divert resources away from the planned 
improvements. However, deferring major or minor capital improvements 
can ultimately result in higher costs to the utilities. For example, 
additional costs may be incurred to repair damage associated with the 
failure of a major asset that was not replaced when planned. 

Some Utilities Had Pipelines in Poor Condition and Rehabilitation and
Replacement Rates That Were Less Than Desired: 

In looking at how utilities were managing their existing capital 
assets, we decided to focus on utilities’ pipelines for several 
reasons. First, as noted earlier, EPA estimates that underground 
pipelines account for about 75 percent of the nation’s existing capital 
investment in drinking water and wastewater infrastructure. Moreover, 
aging pipelines—including the water supply, transmission, and 
distribution lines at drinking water utilities and the sanitary sewer 
lines and other underground systems at wastewater utilities—represent a 
significant share of the estimated future capital investment needs. In 
May 2001, the American Water Works Association, citing a “huge wave of 
aging pipe infrastructure,” predicted significant increases in pipe 
break rates and repair costs over the next 30 years—even if utilities 
increase their investment in pipe replacement by several times over 
today’s levels. [Footnote 38] According to EPA’s 1999 Drinking Water 
Infrastructure Needs Survey, the largest category of need is the 
installation and rehabilitation of transmission and distribution 
systems—accounting for $83.2 billion, or 55 percent of the needs 
projected through 2019. For wastewater systems, EPA’s 1996 Clean Water 
Needs Survey projected infrastructure-related needs for wastewater 
systems of $128 billion through 2016. However, according to an EPA 
official, the needs survey estimate substantially underestimates the 
needs associated with the rehabilitation and replacement of the 
underground infrastructure because these needs are frequently not 
detected and therefore tend not to be included in long-range capital 
plans. As a result, the national survey tends not to include these 
costs. However, EPA has developed a more comprehensive estimate that 
does include such needs. Although the new estimate has not yet been 
released, the official confirmed that at least half of the projected 
capital need for wastewater systems will be associated with the 
rehabilitation and replacement of the underground infrastructure. 

Given the projected needs for rehabilitating and replacing drinking 
water and wastewater pipelines, we asked for more detailed information 
on their age and condition. Among other things, this enabled us to 
explore the relationship between the age and condition of utilities’ 
pipelines and their rehabilitation/replacement activities. [Footnote 
39] 

Age and Condition of Pipelines: 

For our survey, we asked the utilities to estimate the percentage of 
their pipelines that were installed during each 25-year period between 
1900 and 2000, as well as prior to 1900 and from 2000 to the present. 
Our results indicate that, in general, for about a third of utilities, 
a significant portion of their pipelines is relatively new—50 percent 
or more was built since 1975. At the other end of the spectrum, for an 
estimated 5 percent of the utilities, a significant portion of their 
pipelines is quite old: 50 percent or more was built before 1925. 

Also, according to our survey, significant portions of pipelines are in 
poor condition at some utilities. Specifically, we estimate that for 
more than one-third of utilities, 20 percent or more of their pipelines 
were nearing the end of their useful life; and for 1 in 10 utilities, 
50 percent or more of their pipelines were nearing the end of their 
useful life. 

By size and type of utility, our survey results indicate the following: 

* Utilities with 20 percent or more of their pipelines in poor condition
tended to be smaller. In the case of drinking water utilities, an 
estimated 35 percent of the systems serving 10,001 to 25,000 people and 
41 percent of the systems serving 25,001 to 50,000 people fell into 
this category, compared with 24 percent of the largest systems (those 
serving over 100,000 people). Among wastewater utilities, the survey 
data indicate that 42 percent of the smallest (serving 10,001 to 25,000 
people) have at least 20 percent of their pipelines in poor condition, 
compared with 24 percent of the largest systems. We found no 
statistically significant differences between utilities in other size 
categories. 

* Wastewater utilities with 50 percent or more of their pipelines in 
poor condition also tended to be smaller. A somewhat larger percentage 
of the systems serving populations of 10,001 to 25,000 and 25,001 to 
50,000 fell into this category than systems serving more than 100,000 
people (an estimated 14 and 13 percent, respectively, compared with 3 
percent). We found no statistical differences among the population size 
categories for drinking water utilities. 

* There was no statistical difference between public and privately owned
drinking water utilities in terms of the percentage of pipelines 
reported to be nearing the end of their useful life. 

In exploring the relationship between age and condition of the 
pipelines, we found some indication that utilities with a preponderance 
of “newer” pipelines were less likely to have pipelines in poor 
condition. For example, according to our survey, among drinking water 
utilities that had built three-quarters or more of their pipelines 
since 1950, an estimated 47 percent of the utilities reported having 20 
percent or more of their pipelines nearing the end of its useful life. 
In contrast, an estimated 72 percent of the utilities that reported 
having less than 20 percent of their pipelines in poor condition had a 
preponderance of newer pipelines. Our findings were similar with regard 
to wastewater utilities. 

However, the relationship between pipeline age and condition was not
consistent. Indeed, industry studies have found that older pipe 
typically has a longer life expectancy than pipe of more recent vintage 
because of the type of material used, manufacturing techniques, and 
other factors. In addition, technological advances in pipeline 
rehabilitation allow drinking water and wastewater utilities to extend 
the useful life of existing pipelines by installing special liners, 
injecting grout or epoxy, or using other techniques. 

Finally, we found little or no relationship between the condition of
utilities’ pipelines and the frequency with which the utilities had 
raised their user rates during the 10-year period from 1992 to 2001. 
Utilities with higher percentages of pipelines nearing the end of their 
useful life did not increase rates with any greater or lesser frequency 
than utilities with smaller percentages of such pipelines. 

Rehabilitation and Replacement Activities: 

While no industry benchmark exists for the optimal pace of pipeline 
rehabilitation and replacement that is applicable to all utilities, our 
survey shows that nearly two-thirds of utilities have fallen short of 
their desired pace of rehabilitation and replacement. 

Little consensus exists among industry experts regarding what the
appropriate rate of pipeline rehabilitation and replacement is for the
average utility. Some experts have expressed concern that even though
utilities may have kept up with the workload so far, the pace of 
pipeline upgrades will have to increase significantly because much of 
the existing pipeline is nearing the end of its useful life. For 
example, according to the industry report, Dawn of the Replacement Era, 
the United States is not so much faced with making up for an historical 
gap in the level of replacement funding, but it now has a compelling 
need to increase spending on pipeline replacement to prevent a serious 
funding gap from developing. Footnote 40] The report also points out 
that as pipes age, they tend to break more frequently, and utilities 
will be experiencing an estimated three-fold increase in pipeline 
repair costs at the same time replacement costs are rising. On the 
other hand, some experts believe that utilities are already facing a 
backlog of work. As the Water Environment Research Foundation reported 
in 2000, “years of reactive maintenance and minimal expenditures on 
sewers have left a huge backlog of repair and renewal work.” [Footnote 
41] 

While we could not compare our data to an industry benchmark because
the optimal pace of pipeline rehabilitation and replacement is best
determined on a utility-by-utility basis, we did examine the extent to 
which utilities were achieving what they had determined to be 
appropriate for their own circumstances. We found that many of them 
were falling short of their goals. As shown in figure 2, for many 
drinking water and wastewater utilities, a significant disparity exists 
between utilities’ actual rehabilitation and replacement of pipelines 
and the rate at which they believe it should be occurring.

Our survey indicates that roughly half of the utilities actually 
rehabilitated or replaced 1 percent or less of their pipelines 
annually, even though an estimated 89 percent of drinking water 
utilities and 76 percent of wastewater utilities believed that a higher 
level of rehabilitation and replacement should be occurring. More 
specifically, about 35 percent of drinking water utilities and 42 
percent wastewater utilities believed that they should be annually 
rehabilitating or replacing more than 4 percent of their pipelines; 
yet, only an estimated 18 percent of these utilities were actually 
doing so. Table 5 shows in more detail how utilities’ desired rates of 
rehabilitation and replacement compared with their average actual rates
during recent fiscal years (1998 through 2000).

to provide separate answers for the percentage of pipeline subject to
rehabilitation and the percentage subject to replacement, to the extent 
possible. For the purposes of this analysis, we added the percentages 
together to get combined rehabilitation and replacement rates. Totals 
may not add to 100 due to rounding. 

Legend: Numbers are percentage of utilities within each category of 
desired rehabilitation/replacement rate. Shaded areas denote cases in 
which utilities’ actual rehabilitation and replacement of pipelines was 
less than the utilities’ desired rate.

[End of table] 

For replacement rates alone, we found that about 60 percent of the
drinking water utilities and 77 percent of the wastewater utilities 
replaced 1 percent or less of their pipelines annually, on average, 
from fiscal years 1998 through 2000. [Footnote 42] At these rates, the 
utilities would need at least 100 years to replace their entire 
inventory of pipelines. These results are consistent with a 2001 study 
by the American Water Works Association Research Foundation, which 
reported that at least 9 of the 15 North American utilities examined in 
the study replaced their water mains at an annual rate ranging from 0.1 
percent to 1 percent. [Footnote 43] According to a 1994 Research 
Foundation study, an estimated 4,400 miles of pipeline, or 0.5 percent 
of the estimated 880,000 miles of existing pipeline, were being 
replaced annually. [Footnote 44] The study concluded that utilities 
would replace any given pipe only once every 200 years at the estimated 
replacement rate and noted that no pipe has a 200-year life expectancy. 

We also took a closer look at utilities with large percentages of 
pipelines nearing the end of their useful life. Specifically, we 
examined whether these utilities were any more or less likely than 
utilities with small percentages of pipelines nearing the end of their 
useful life to (1) have a preventive rehabilitation and replacement 
program or (2) achieve their desired rehabilitation and replacement 
rate for their pipelines. We found the following: 

* Utilities with a large percentage of pipelines nearing the end of 
their useful life were no more likely to have a preventive 
rehabilitation and replacement program than utilities with a small 
percentage of pipelines nearing the end of their useful life. 

* Utilities with larger percentages of pipelines nearing the end of 
their useful life were somewhat less likely to have achieved their 
desired rehabilitation and replacement rate. More specifically, a 
larger proportion of utilities with 20 percent or more of their 
pipelines nearing the end of their useful life did not achieve their 
desired rates than those with less than 20 percent of pipelines nearing 
the end of their useful life (the estimates were about 80 percent and 
about 50 percent of utilities, respectively). When we compared those 
having 50 percent or more of their pipelines nearing the end of their 
useful life with those having less than 50 percent nearing the end of 
their useful life, we found a similar difference. 

Many Utilities Deferred Maintenance, Capital Improvements, or Both: 

We asked the surveyed utilities whether, in their most recent fiscal 
year, they had deferred maintenance, minor capital improvements, and/or 
major capital improvements as a result of insufficient funding. We 
found that about one-third of the utilities deferred maintenance 
expenditures and similar percentages of utilities deferred expenditures 
in the other categories. 

By size and type of ownership, we found the following: 

* With one exception, there were no statistically significant 
differences among utilities of different sizes. However, the smallest 
drinking water utilities (serving populations of 10,001 to 25,000) were 
more likely to defer maintenance and major capital projects than 
utilities serving populations of 25,001 to 50,000—an estimated 35 
percent compared with 24 percent for maintenance and an estimated 47 
percent compared with 33 percent for major capital projects. 

* Public drinking water utilities were more likely than their privately 
owned counterparts to defer maintenance (an estimated 31 percent 
compared with 12 percent) and major capital projects (42 percent 
compared with 26 percent). 

About 20 percent of utilities had deferred expenditures in all three
categories. Although we found no statistical differences among these
utilities based on population size, we found that public drinking water
utilities were more likely to defer all three than privately owned 
drinking water utilities (an estimated 21 percent compared with 7 
percent). 

Utilities that deferred expenditures in all three categories because
available funding was not sufficient might also be expected to have 
other indications of financial problems. However, we found no 
statistically significant differences in the percentage of utilities 
that were unable to cover their cost of providing service through local 
sources of revenue, whether or not they deferred maintenance and 
capital improvements. Similarly, we found only one significant 
difference when we compared the frequency of rate increases among the 
utilities that deferred expenditures: wastewater utilities that had 
deferred expenditures in all three categories were somewhat more likely 
to have had frequent rate increases (8 to 10 rate increases from 1992 
to 2001) than no increases during this period (an estimated 25 percent 
were in the first category, compared with 11 percent in the latter). 
[Footnote 45] 

Most Utilities Had Capital Improvement Plans, but Many Questioned 
Adequacy of Future Funding: 

According to our survey, the large majority—about 90 percent—of 
utilities had capital improvement plans to identify future capital 
needs, and most also had plans for financing the projects identified. 
However, almost half of the utilities anticipated that their projected 
funding would not be sufficient to cover future needs over the next 5 
to 10 years. 

Utilities prepare capital improvement plans to identify future needs for
plant and equipment as a result of the rehabilitation and replacement of
existing infrastructure, compliance with regulatory requirements, and
growth. According to EPA and industry sources, such plans should contain
detailed information on all needed capital projects, the reasons for 
each project, and their estimated cost, for a specified period of time. 
Experts also agree that capital improvement plans should be updated on 
a regular basis to reflect changes in existing circumstances. The 
projected financing for needed capital projects should be identified 
and detailed in the utility’s capital improvement plan, a separate 
financing plan, or some other document, and ideally, should reflect 
several alternative scenarios and their impact on user rates. 

Most Utilities Had Capital Improvement Plans: 

Overall, our survey results indicate that about 90 percent of drinking 
water and wastewater utilities had capital improvement plans to 
identify future capital needs. The smallest systems, serving 10,001 to 
25,000 people, were slightly less likely than larger systems to have 
had such plans (an estimated 86 percent for drinking water utilities 
and 81 percent for wastewater utilities). Also, the survey results show 
that about 90 percent of utilities reviewed their needs 
annually—whether or not they had developed formal plans. 

Experts familiar with capital planning in the utility industry recommend
that capital improvement plans have a longer-term focus and cover a
5- to 10-year period, at a minimum. The industry handbook developed by
the Association of Metropolitan Sewerage Agencies recommends that
utilities also forecast system replacement and expansion needs for a 
much longer period of time—even 50 to 100 years, if possible.
[Footnote 46] Our survey results indicate that about 95 percent of the 
utilities’ capital improvement plans covered 5 years or more—with about 
25 percent of drinking water utilities and about 20 percent of 
wastewater utilities covering 10 years or more. The remaining utilities 
had plans covering 4 years or less. 

Most Utilities Had Plans for Financing Capital Needs, but Many 
Questioned Whether Funds Would Be Adequate: 

Most of the drinking water and wastewater utilities with capital
improvement plans also had plans for financing the projects identified 
in their plans. According to our survey, 86 percent of the utilities 
had such plans, including virtually all of the largest utilities (those 
serving populations of over 100,000). Utilities with financing plans 
were somewhat more likely to dedicate a portion of their income to 
future capital needs. Specifically, our survey results indicate that 
about 73 percent of the drinking water utilities with plans considered 
future capital needs when developing their user rates by dedicating a 
portion of their income to future needs, while about 59 percent of the 
utilities without plans did so. In the case of wastewater utilities, an 
estimated 78 percent of the utilities with plans dedicated a portion of 
their income to future needs, while about 48 percent of those without 
plans did so. 

According to our survey results, about 45 percent of the drinking water
and wastewater utilities anticipated that their projected funding would 
not be sufficient to cover future needs over the next 5 to 10 years. The
comprehensive industry handbook developed by the Association of 
Metropolitan Sewerage Agencies recommends that drinking water and
wastewater utilities use a detailed financial planning window of at 
least 5 to 10 years to provide for future capital needs. However, the 
handbook notes that some utilities have a very narrow time line for 
financial planning; while such utilities may identify their future 
capital needs over a 5- to 10-year period, they only address detailed 
financial forecasting as part of their annual budget development 
process. 

By utility size and type of ownership, we found the following: 

* Drinking water utilities serving populations of 10,001 to 25,000 and 
50,001 to 100,000 were more likely to believe that their projected 
revenues will be insufficient to cover anticipated future needs than 
the utilities serving over 100,000 people (an estimated 47 percent for 
the smaller population groups compared with 35 percent for the largest 
population group). 

* There were no statistically significant differences among wastewater
utilities of different sizes. 

* Public drinking water utilities were somewhat more likely than 
privately owned systems to have concerns about future funding (an 
estimated 44 percent compared with 33 percent). 

We also looked at the relationship between the extent to which utilities
anticipated that their projected funding will be adequate to meet future
needs and a number of other key variables related to funding. As table 6
shows, we found that both drinking water and wastewater utilities that
anticipated that future funding will be inadequate were significantly 
more likely to have deferred maintenance, minor capital expenditures, 
or major capital expenditures in recent years compared with utilities 
that anticipated adequate future funding.

Chapter 4: Profit Potential Is Key Factor in Private Companies’ 
Decisions to Assume Operation or Ownership of Utilities: 

In making decisions to enter into privatization agreements with publicly
owned utilities or the governmental entities they serve, the private 
companies we contacted primarily focus on a venture’s potential to 
generate profits for the company. In assessing profit potential, the
companies cited several specific criteria, such as the extent of 
opportunities to enhance operational efficiency, the utility’s 
proximity to the companies’ existing operations, and the potential for 
system growth. They also noted that state policies can influence 
privatization agreements. For example, two states that we contacted 
restrict the use of design-build-operate contracts, which give a single 
entity complete control over a project. Other states offer incentives 
to encourage the takeover of financially troubled public utilities. 

Profit Potential Is Key Consideration for Private Companies: 

Privatization agreements range from contracts to operate and maintain
drinking water or wastewater facilities to outright ownership by private
entities. Regardless of the specific type of agreement, the companies we
contacted all evaluate the potential for profits when considering 
entering into privatization agreements. Each of the five companies 
employs a somewhat different business strategy in its pursuit of 
privatization agreements, such as placing more emphasis on contract 
operations rather than on ownership of utilities or focusing on 
utilities of particular sizes or in particular locations. While none of 
the companies would consider entering into a privatization agreement 
without the potential to make a profit, differences in the companies’ 
business strategies had some influence on the relative importance of 
the factors company officials cited as affecting profit potential. 

Companies Engage in Different Types of Privatization Arrangements: 

Privatization can take different forms, ranging from contracting for
specific services to selling the facilities to a private company. The 
most common form of privatization is contracting, which typically 
entails a competition among private bidders to perform certain 
activities. In the case of drinking water and wastewater utilities, 
such activities typically include operation and maintenance for a set 
period of time. When a municipality contracts with a private company 
for services, the government or public entity remains the financier and 
has management and policy control over the quality of services to be 
provided. According to an official at one of the largest companies we 
contacted, the most common type of public-private partnership in the 
field of drinking water and wastewater utilities has historically been 
operations and maintenance contracts covering from 1- to 5-year 
periods. 

A variation of this type of contractual arrangement is called “design-
build-operate,” in which a private company (or a team of companies) 
designs, builds, and operates a facility under one agreement. Under 
this model, the local government retains ownership of the utility once 
it has been constructed and the contractor is responsible for operation 
and maintenance over the life of the contract, often a long-term 
agreement of 10 to 20 years. 

In some instances, privatization involves transferring the ownership of
utility assets from a municipality to the private sector. Once the 
assets have been sold, the municipality generally has no role in their 
financial support, management, or oversight. Collectively, the 
companies we contacted are involved in all of these types of 
privatization agreements. 

Companies Cite Several Criteria for Evaluating Ventures’ Profit 
Potential: 

According to officials of the five companies, criteria important to
assessing the profitability of a proposed agreement to privatize a 
utility include the potential to improve the efficiency of the 
utility’s operations; the proximity to the company’s other utility 
operations; the potential for system growth; the terms of a proposed 
contract; and the potential need for capital investments. The relative 
importance of the factors varies, depending on the companies’ business 
strategies. 

All five of the companies saw the opportunity to improve the efficiency 
of a utility’s operations as a key factor in evaluating candidates for
privatization because of its potential impact on the companies’ ability 
to make a profit. For example, in two cases, company officials said that
operating efficiency can be improved by either reworking resources
already in place (e.g., training workers or correcting inefficient 
practices) or investing in cost-effective improvements (e.g., 
computerizing operations or installing energy-efficient equipment). 
Officials in two other companies commented that the potential for 
correcting operational inefficiencies exists because public utilities 
often lack the financial or technical capabilities of companies that 
are in the business of assuming the operation or ownership of drinking 
water and wastewater utilities. 

Officials of one company said that they focus on three major cost areas 
in looking for ways to increase efficiency: employees, energy, and 
chemicals. The officials acknowledged that dealing with employees can 
be sensitive because of concerns about potential job losses; thus, the 
savings in this area typically come about as a result of attrition or 
retraining. Energy consumption is a target of operational improvements 
because it accounts for about one-third of the average utility’s 
operating costs. Because chemicals are also a major cost element, 
utilities can achieve significant savings through bulk purchases. 

At drinking water utilities, another area with significant potential 
for cost savings is the reduction of “unaccounted for” water. This 
water represents the difference between the volume of water that leaves 
the treatment works and the volume that is “metered” (that is, used by 
customers according to their water meters). For example, utilities may 
experience leaks in their water distribution systems. According to an 
official of one of the largest companies we contacted, it is not 
uncommon for many communities to be unable to account for 25 percent or 
more of the water they produce. 

The companies provided examples of the types of operational 
improvements that have resulted in cost savings or increased revenues: 

* At a California drinking water utility, a company worked with state
regulatory authorities to reduce the utility’s requirements to monitor 
water quality, thus achieving over $200,000 savings in annual 
laboratory costs. 

* At another utility, also in California, the company introduced
improvements that reduced energy consumption by 13 percent and certain
treatment costs by 22 percent. 

* At a Georgia utility, the same company implemented a leak detection
program that reduced unaccounted for water from 60 percent to 30 
percent. 

* Another company helped a Massachusetts wastewater utility to improve
the treatment process and modify the utility’s incinerator, which 
reduced incineration costs by about 75 percent. 

* At a Texas drinking water utility, a meter replacement program is
projected to increase water revenues by $1 million over 10 years. 

Other criteria cited by the companies for evaluating profit potential of
privatization opportunities include the following: 

* Proximity to the companies’ existing operations. Four of the five
companies we contacted consider the utilities’ proximity to their other
operations when they decide whether or not to pursue a public-private
partnership. In one case, company officials told us that their 
preference is to add new business in close proximity to existing 
operations because, among other things, the company’s technical experts 
can make site visits at a reasonable cost. Officials from the other 
companies indicated that proximity to existing operations allows them 
to take advantage of economies of scale. For example, certain commonly 
used products and equipment such as chemicals, pipe, and meters can be 
purchased in bulk at lower costs and, with an expanded service area and 
customer base, the companies can spread the costs over more customers. 
An official from one of the companies commented that proximity is more 
of a consideration in the case of smaller utilities because they get 
more of a benefit than larger systems from sharing staff and other 
resources. 

Increasing efficiency through economies of scale may be more difficult,
however, in the case of relatively small and isolated utilities. 
According to an official of the National Association of Water 
Companies, a plan to consolidate several small, remote utilities 
probably would not be cost-effective where miles of pipelines were 
needed, for example, to connect the remote utilities. On the other 
hand, he noted that there are ways that privatization agreements with 
such utilities can be profitable. For example, private companies can 
bring in professional management expertise to oversee multiple 
utilities, use a limited number of system operators to run several 
small utilities that do not require full-time operators, and 
consolidate purchases of equipment and chemicals to get better prices. 

* Potential for system growth. The projected growth in the population
served by a utility—its customer base—was also mentioned as a factor by
several companies. Officials from one company told us that projected
population growth allows the company to increase its customer base and
thus be assured of additional revenues. According to officials of 
another company, a utility’s growth potential is more of a 
consideration when the privatization opportunity involves a smaller 
utility. The officials indicated that they examine this factor more 
closely at smaller utilities because these utilities may have to grow 
before they become profitable. According to an official of the National 
Rural Water Association, private companies generally consider public 
water systems serving rural, low-density populations an unattractive 
investment. Further, according to an official of the Kansas Rural Water 
Association, small towns often have relatively high water and sewer 
rates as well as a greater proportion of households with lower median 
incomes. [Footnote 47] 

* Terms of operation and maintenance contracts. Three of the companies 
told us that, in the case of operation and maintenance agreements, the 
length of time covered by a proposed contract is a key factor in their 
decisions. Generally, the longer the time period covered by the 
contract, the more time the company has to recoup its investment. 
According to an official at one of the largest companies we contacted, 
over the past 2 years the number of longer-term contracts has increased
markedly, partly because of the increased use of design-build-operate
contracts. The official also cited two examples of restrictive contract
provisions that his company views as deal breakers. First, he said that
some communities insist on unlimited liability guarantees from companies
that bid on privatization contracts; however, responsible companies have
to limit their liability. Second, restrictive maintenance provisions can
impose a ceiling—typically $10,000—on a contractor’s responsibility for
maintenance items. According to the company official, this kind of
restriction limits a company’s ability to offer comprehensive solutions,
which could be more cost-effective over the long term. 

* The potential need for capital investment. The extent to which
companies foresee a need to invest their funds to repair, replace, or
upgrade utilities’ plant and equipment can affect whether they enter 
into an agreement or what type of agreement they enter. Officials from 
several companies indicated that the condition of a utility’s 
infrastructure is not a deterrent as long as the amount and nature of 
any investment needs are accurately reflected in the contract and the 
company is fairly compensated. One official commented that it is 
difficult to operate a utility as a contractor when the company has no 
control over the level of capital investment—and the level has not been 
adequate. In these situations, his company has tried to become more 
involved in developing capital improvement plans for the utilities they 
manage and to assume more responsibility for capital investments in 
general. The same official also commented that even if the condition of 
a utility’s infrastructure is adequate, company officials may determine 
that a substantial investment will be required just to make the utility 
more efficient. 

* Other factors. For drinking water utilities, officials of two 
companies noted the importance of a reliable water source. For example, 
according to one of the companies, an unreliable source limits profit 
potential because it can be costly to purchase water from other systems 
or develop a new source. For wastewater utilities, two companies 
pointed out that the presence of large quantities of industrial waste 
in the influent (the water flowing into the treatment facilities) can 
be a deterrent to an agreement. For example, one company official noted 
that industrial waste can increase treatment costs as well as pose a 
potential liability issue for the facility owner or operator. 

States’ Policies May Also Influence Companies’ Decisions: 

In addition to identifying the site-specific factors they consider in
evaluating privatization opportunities, representatives from all five 
of the companies we contacted also commented on state requirements or
policies that can facilitate or impede privatization arrangements. We
contacted officials of eight states identified by the five companies, 
EPA, and industry officials as having particular requirements or 
policies that affect privatization, either positively or negatively. 
Our contacts included representatives from the state agencies that 
oversee the drinking water and wastewater management programs and the 
public utility commissions, which regulate the rates and other 
activities of privately owned (and, in some cases, publicly owned) 
utilities. The state officials told us that their agencies are 
primarily interested in the delivery of adequate service to the public, 
whether the service is provided by publicly or privately owned 
utilities. However, the states have some requirements and policies that 
can affect companies’ privatization decisions, including laws that 
address the acquisition of “troubled” utilities [Footnote 48] and the 
use of design-build-operate contracts. 

State regulators in Indiana and Pennsylvania have established programs
that provide utilities in good standing with incentives to acquire or 
take over troubled utilities. For example, under Indiana’s program, the
acquiring utility is permitted to add an “acquisition adjustment” to 
its user rates as an incentive for taking over a troubled utility. 
Similarly, Pennsylvania’s incentive program allows, under certain 
circumstances, the acquiring utility to increase the rate of return on 
its investment and thus, accelerate the recovery of costs incurred for 
needed system improvements. This program targets small utilities that 
lack the financial, managerial, and/or technical capacity to comply 
with applicable regulatory requirements. To encourage faster 
replacement of aging water distribution systems, Pennsylvania also 
established a special pipe surcharge program—the Distribution System 
Improvement Charge Program—in which companies make improvements to 
utilities’ distribution systems. In return, the companies are allowed 
to raise rates by up to 5 percent without going through a formal 
hearing process. 

In addition to the incentive programs, four of the eight states we
contacted—Connecticut, Indiana, New Jersey, and Pennsylvania—have
enacted laws that give state regulators the authority to provide for
qualified utilities to acquire or take over certain “troubled” 
utilities to resolve specific problems. For example, in New Jersey, the 
state may order the acquisition of small drinking water or wastewater 
utilities (with less than 1,000 connections) by a suitable public 
utility or a privately owned company if the small utilities fail to 
comply with an enforcement order. In New Jersey and the other states, 
the orders are directed at serious violations involving, for example, 
the availability, potability, or provision of water at adequate volume 
or pressure or the failure to remedy “severe deficiencies.” While these 
laws could affect companies’ privatization decisions by compelling the 
takeover of particular utilities, state officials indicated that the 
laws are rarely used. 

Other state requirements or policies can affect the use of design-build-
operate contracts, which couple the design and construction of new, 
expanded, or upgraded facilities with comprehensive agreements to 
operate and maintain the facilities. For example, Texas officials told 
us that professional services such as engineering design must be 
procured using a qualification-based selection while construction 
services must be procured using a bidding process. As a result, the 
design, construction, and operating services cannot be combined in a 
single procurement. The situation in Pennsylvania was similar; a state 
official told us that the state’s procurement regulations have not been 
updated to allow the kind of combined procurement contemplated in a 
design-build-operate contract. In other instances, state laws can also 
facilitate the use of design-build-operate contracts. For example, 
Georgia amended its official code in 2000 to specifically authorize 
local governments to enter into contracts with private entities “for 
the design, construction, repair, reconditioning, replacement, 
maintenance, and operation of the system, or any combination of such 
services” at drinking water or wastewater systems. 

We also identified certain requirements that could affect companies’
privatization decisions and are specific to individual states. For
example, New Jersey law requires that privatization proposals be 
approved by the applicable state agency. Among other things, state
regulators assess the financial and technical capacity of the private
company; the reasonableness of the contract terms; the extent to which
the interests of utility customers are protected; and whether the 
particular contract terms, such as user charges and the status of 
current utility employees, are clearly spelled out. In addition, under 
California law, sales of drinking water and wastewater systems must be 
approved by voters in the affected community.

GAO: 

Survey of Drinking Water Utilities: 

Introduction: 
The U.S. General Accounting Office (GAO) is an agency that assists the 
U.S. Congress in evaluating federal programs. In anticipation of 
analyzing a number of water infrastructure-related proposals this year, 
the Committee on Environment and Public Works, U. S. Senate, has asked 
GAO to collect information on user charges and infrastructure planning 
at both public and privately owned drinking water utilities. 

Your utility has been randomly selected to receive this nationwide 
survey of drinking water utilities. As part of our study, we are asking 
for your help in completing this survey so that we can provide 
congressional decisionmakers with the information they need. 

Part I of the survey collects general information on your utility. Part 
II collects information on funding from user charges and other sources. 
Part III collects information on your utility's infrastructure 
planning. 

Instructions: 

When answering the questions in this questionnaire, please coordinate 
with the appropriate staff who have knowledge of your utility's user 
charges, other sources of funds, and capital improvement plans.
Please return your completed questionnaire in the enclosed, pre-
addressed business reply envelope. If the envelope is misplaced, the 
return address is:

GAO: 

Survey of Wastewater Water Utilities: 

Introduction: 

The U.S. General Accounting Office (GAO) is an agency that assists the 
U.S. Congress in evaluating federal programs. In anticipation of 
analyzing a number of water infrastructure-related proposals this year, 
the Committee on Environment and Public Works, U. S. Senate, has asked 
GAO to collect information on user charges and infrastructure planning 
at both public and privately owned drinking water utilities. 

Your utility has been randomly selected to receive this nationwide 
survey of drinking water utilities. As part of our study, we are asking 
for your help in completing this survey so that we can provide 
congressional decisionmakers with the information they need. 

Part I of the survey collects general information on your utility. Part 
II collects information on funding from user charges and other sources. 
Part III collects information on your utility's infrastructure 
planning. 

Instructions: 

When answering the questions in this questionnaire, please coordinate 
with the appropriate staff who have knowledge of your utility's user 
charges, other sources of funds, and capital improvement plans.
Please return your completed questionnaire in the enclosed, pre-
addressed business reply envelope. If the envelope is misplaced, the 
return address is: 

U.S. General Accounting Office: 
Attn: Lisa Turner:
441 G Street, NW – Room 2T23 A: 
Washington, DC 20548-0001:

[4] For example, nearly 60 percent of the community drinking water 
systems serve populations of 500 or fewer. 

[5] For the purposes of our review, we focused on wastewater treatment 
facilities only to avoid double counting collection facilities that 
serve multiple treatment plants. According to an EPA official, 
wastewater treatment facilities serving 10,000 or more people account
for approximately 65 percent of the estimated infrastructure needs for 
wastewater utilities.

and Wastewater Infrastructure, (Washington, D.C.: May 2002). The report 
states that assumptions about the rate at which drinking water pipes 
are replaced, the savings associated with improved efficiency, the 
costs of controlling combined sewer overflows, and the borrowing term 
are primarily responsible for the difference between the low and high 
estimates. 

[12] Among the associations that support the principle that utilities 
should be self-sustaining are the American Water Works Association, the 
Association of Metropolitan Sewerage Agencies, the Association of State 
Drinking Water Administrators, the National Association of Water

[16] As noted earlier, our November 2001 report addressed the amounts 
and sources of federal and state financial assistance for drinking 
water and wastewater infrastructure during fiscal years 1991 through 
2000. See GAO-02-134. 

[17] We did not send questionnaires to drinking water and wastewater 
utilities whose ownership was specified as “federal government,” “state 
government,” “native American,” or “not specified.” 

[18] The five drinking water and five wastewater utilities were chosen 
to represent a variety of size categories (based on population served 
by each utility) and both public and private ownership. 

[19] The National Regulatory Research Institute was established by the 
National Association of Regulatory Utility Commissioners in 1976 at the 
Ohio State University and is the official research arm of the 
association. The Institute provides research and assistance to state
public utility commissions and other selected national and 
international clients. See National Regulatory Research Institute,

Alternatives (Nov. 1993) p. 63. 

[20] Meeting Water Utility Revenue Requirements: Financing and 
Ratemaking Alternatives, p. 64. 

[21] Our survey allowed utilities to report miscellaneous costs under 
an “Other” category, and some utilities did so. When appropriate, we 
recategorized these costs. For example, some public systems reported 
transfers to other city departments in the Other category; when the 
survey document indicated that the transfer was for administrative 
services, such as accounting or legal services, we included the amount 
in the “Operations and Maintenance” category. When it was not possible 
to discern a more appropriate category for particular costs, we 
included them in the calculation of cost of service as other costs. 

[22] We considered using the cash needs approach to calculate the cost 
of service because most of our respondents were public utilities and, 
as such, were more likely to use the applicable cost categories. 
However, while our survey requested information on the amount of 
utilities’ capital expenditures during their most recently completed 
fiscal year, the survey did not specifically request information on 
“capital expenditures not financed by either debt capital or 
contributions.” 

[23] U.S Environmental Protection Agency, National Characteristics of 
Drinking Water Systems Serving Populations Under 10,000, EPA 816-R-99-
010 (Washington, D.C.: July 1999). Among other things, the report 
compares the financial characteristics of several different subsets of 
small systems serving less than 10,000 people to the systems that serve
more than 10,000 people in a number of ways, including the ratio of 
annual debt service payments to net available revenue (i.e., total 
revenues minus operating and maintenance expenses). 

[24] U.S. Environmental Protection Agency, National Wastewater User Fee 
Study of the Construction Grants Program, EPA 430/09-90-011 
(Washington, D.C.: September 1990). 

[25] The user charge requirement applies to construction grants awarded 
under title II of the Clean Water Act. According to EPA, although most 
of these grants were expended long ago, the user charge requirement 
applies “in perpetuity,” as long as the facilities for which the grants 
were used remain in operation. 

[26] National Wastewater User Fee Study of the Construction Grants 
Program, p. 2. The last year for which the Congress authorized funding 
for construction grants was 1990. 

[27] National Characteristics of Drinking Water Systems Serving 
Populations Under 10,000, p. 4-1. EPA compared the financial 
characteristics of small systems and larger ones, in this instance, by 
dividing operating revenues by operation and maintenance expenses and
deriving an “operating ratio” as a measure of financial health. 
Generally, an operating ratio below 1 is considered to be an indicator 
of weak financial health. 

[28] About 21 percent of the drinking water utilities and 23 percent of 
the wastewater utilities indicated that they had local sources of 
funding in addition to user charges, but they did not report an amount. 
We have no way of knowing whether the amounts these utilities reported 
as user charges actually represented revenues from all local sources or 
from user charges alone. We excluded these utilities when we calculated 
the percentage of locally generated funding represented by user 
charges.

Populations Under 10,000, p. 4-8. 

[30] Association of Metropolitan Sewerage Agencies, AMSA 1999 Financial 
Survey: A National Survey of Municipal Wastewater Management Financing 
Trends (1999), pp. 13, 65. The survey included 119 utilities serving 
populations greater than 21,000. Of the 93 utilities that provided 
information on how long current rates had been in effect, 45 reported 
that their rates had been in effect for less than 1 year prior to the 
survey; the longest period of time that a rate was unchanged was 17 
years. 

[31] The Association of Metropolitan Sewerage Agencies developed the 
handbook, Managing Public Infrastructure Assets to Minimize Cost and 
Maximize Performance, in partnership with the Association of 
Metropolitan Water Agencies, the American Water Works Association, and 
the Water Environment Federation, to help water and wastewater 
utilities adopt advanced management methods that can reduce long-term 
costs and improve service to customers. 

[32] Managing Public Infrastructure Assets to Minimize Cost and 
Maximize Performance, p. 154. 

[33] We focused on elements of an asset management system identified by 
the Governmental Accounting Standards Board in a June 30, 1999, 
statement that made comprehensive changes in state and local 
governments’ financial reporting. Among other things, it requires, for 
the first time, the governments to report information about public 
infrastructure assets, including their drinking water and wastewater 
facilities. Specifically, the governments must begin reporting 
depreciation of their capital assets or implement an asset management
system. See Governmental Accounting Standards Board Statement No. 34, 
Basic Financial Statements—and Management’s Discussion and Analysis—for 
State and Local Governments. 

[34] Three percent of drinking water utilities and 4 percent of 
wastewater utilities did not indicate that they did or did not have a 
plan.

identify and document best practices in planning for the rehabilitation
and replacement of aging, deteriorated water main piping.

[39] For wastewater utilities, the information on the condition of 
pipeline, and its rehabilitation and replacement, represents what the 
utilities reported for their sanitary sewer lines. Our survey also 
requested information on combined storm/sanitary sewer lines, but 
because only about 20 percent of the utilities reported having such 
lines, we did not include the information in our analysis.

reported for the sanitary sewer lines.

[45] For the latter two analyses, we also compared utilities that 
deferred expenditures in all three areas with the utilities that had 
not deferred expenditures in any of the categories. We found no 
statistical differences in their ability to cover their cost of 
providing service or the frequency of their rate increases.

[48] Under some state laws, either public or privately owned utilities 
may be the “acquiring utility; in other cases, state law specifies that 
the acquiring utility must be privately owned.”
