Water Infrastructure Financing: Proposals to Create a WIFIA Program

Summary
Policy makers have recently been considering several legislative options to help finance water
infrastructure projects, including projects to build and upgrade wastewater and drinking water
treatment systems. This report examines one particular option being debated, creation of a “Water
Infrastructure Finance and Innovation Act,” or WIFIA, program. Although several other
approaches have also been proposed, much of the recent legislative and policy attention has been
on WIFIA. In the 113th Congress, House and Senate conferees have included a WIFIA pilot
program in H.R. 3080, the Water Resources Reform and Development Act of 2014, or WRRDA.
The conference report adopts WIFIA provisions from Senate-passed S. 601 with some additions
and modifications. H.R. 3080 as passed by the House did not include similar provisions.
The WIFIA concept is modeled after a similar program that assists transportation projects, the
Transportation Infrastructure Finance and Innovation Act, or TIFIA, program. Proponents of the
WIFIA approach, including water utility organizations, cite several potential benefits.
• WIFIA could provide credit assistance to large water infrastructure projects that
otherwise have difficulty obtaining financing.
• Because WIFIA would access funds from the U.S. Treasury at Treasury rates, the
mechanism could lower the cost of capital for borrowers.
• WIFIA assistance would have much less of a federal budgetary effect than
conventional project grants that are not repaid, because only the subsidy cost of a
loan (representing the presumed default rate on loans) would be scored. Thus, if
only an average 10% subsidy cost is charged against budget authority, a $20
million budgetary allocation theoretically supports $200 million in loans.
• To be eligible for assistance, projects must be determined to be creditworthy,
with a revenue stream for repayment, thus limiting the federal government’s
exposure to default and also encouraging private capital investment in the
project.
On the other hand, opponents of the WIFIA approach, including organizations that represent state
environmental agency officials, cite several concerns, which were raised with policy makers
during debate over the pilot program proposed in S. 601.
• Under WIFIA, decision making for financing of water infrastructure projects
would shift from the state and local level to federal officials.
• Funding for a WIFIA program likely would have a detrimental effect on federal
support for established and successful State Revolving Fund (SRF) programs that
provide the largest source of water infrastructure assistance today.
• While WIFIA is intended to assist large and costly projects, the majority of water
infrastructure needs are for smaller projects. Especially if SRF assistance is
decreased, these smaller projects would face significant financing challenges.
• The Congressional Budget Office (CBO) has warned that the costs of a WIFIA
program to the federal budget may be underestimated.

Water Infrastructure Financing: Proposals to Create a WIFIA Program

Introduction
Policy makers have recently been considering several legislative options to help finance water
infrastructure projects, including projects to build and upgrade wastewater and drinking water
treatment systems. This report examines one particular option being debated, creation of a “Water
Infrastructure Finance and Innovation Act,” or WIFIA, program. Although several other
approaches have also been proposed, such as a water infrastructure trust fund,1 much of the recent
legislative and policy attention has been on WIFIA. In the 113th Congress, House and Senate
conferees have included a WIFIA pilot program in H.R. 3080, the Water Resources Reform and
Development Act of 2014, or WRRDA.
Localities are primarily responsible for providing water infrastructure services. According to the
most recent estimates by states and the Environmental Protection Agency (EPA), funding needs
for such facilities total $676 billion over the next 20 years.2 While some analysts and stakeholders
debate these estimates, and whether they understate or overstate capital needs, most agree that
communities face formidable challenges in providing adequate and reliable water infrastructure
services.
Capital investments in water infrastructure are necessary to maintain high quality service that
protects public health and the environment, and capital facilities are a major investment for local
governments. Almost all capital projects are debt-financed (not financed on a pay-as-you-go basis
from ongoing revenues to the water utility). The principal financing tool that local governments
use is issuance of tax-exempt municipal bonds—at least 70% of U.S. water utilities rely on
municipal bonds and other debt to some degree to finance capital investments. In 2011, bonds
issued for water, sewer, and sanitation projects totaled $29.6 billion, of which $14.2 billion was
new-money financing and the remainder was for refunding to refinance prior governmental
bonds.3 Beyond municipal bonds, federal assistance through grants and loans is available for
some projects, but is insufficient to meet all needs. Finally, public-private partnerships, or P3s,
which are long-term contractual arrangements between a public utility and a private company,
provide limited capital financing. While they are increasingly used in transportation and some
other infrastructure sectors, especially P3s that involve private sector debt or equity investment in
a project; most P3s for water infrastructure involve contract operations for operation and
maintenance.
Proposals to Create a WIFIA Program
The WIFIA approach for supporting investment in water infrastructure is modeled after an
existing Transportation Infrastructure Finance and Innovation Act (TIFIA) program. As the name
suggests, only transportation projects are eligible for TIFIA assistance, but operation of the TIFIA

program over the past 15 years has generated interest in creating a similar program for water
infrastructure.4
TIFIA was enacted in 1998 as part of the Transportation Equity Act for the 21st Century (TEA-21;
P.L. 105-178) and was reauthorized in July 2012 in the Moving Ahead for Progress in the 21st
Century Act (MAP-21; P.L. 112-141). TIFIA provides federal credit assistance up to a maximum
of 49% of project costs in the form of secured loans, loan guarantees, and lines of credit (23
U.S.C. 601 et seq.). Transportation projects costing at least $50 million (or at least $25 million in
rural areas) are eligible for TIFIA financing.5 Projects must also have a dedicated revenue stream
to be eligible for credit assistance. TIFIA can provide senior or subordinated debt. With the
enactment of MAP-21, funding authorized for the TIFIA program has increased from $122
million annually to $750 million in FY2013 and $1 billion in FY2014.
Prior to the enactment of MAP-21, a project seeking TIFIA assistance had to satisfy a number of
eligibility criteria such as project cost and planning requirements. Projects were then selected by
the Department of Transportation (DOT) from among those eligible based on eight weighted
factors: private participation (20%); environmental impact (20%); national or regional
significance (20%); project acceleration (12.5%); creditworthiness (12.5%); use of new
technologies (5%); reduced federal grant assistance (5%); and consumption of budget authority
(5%). MAP-21 eliminates these selection criteria and now provides TIFIA assistance purely on a
project’s eligibility. One of the key eligibility criteria is the creditworthiness of the project. To be
eligible, a project’s senior debt obligations and the federal credit instrument must receive an
investment-grade rating from at least one nationally recognized credit agency. The TIFIA
assistance must also be determined to have several beneficial effects: fostering a public-private
partnership, if appropriate; enabling the project to proceed more quickly; and reducing the
contribution of federal grant funding. Other eligibility criteria include satisfying planning and
environmental review requirements and being ready to contract out construction within 90 days
after the obligation of assistance.
Since the beginning of the program in 1998, TIFIA has provided assistance to 35 projects, mostly
in the form of direct loans. Loan amounts ranged from $40 million to $900 million. Total credit
assistance provided over the life of the program amounts to $11.8 billion, as of September 2013.
The amount of credit assistance is much larger than the appropriated amount over this period
because the appropriated funds need only cover the administrative and subsidy cost of the
program (see below for a more detailed discussion of this point). Projects involving TIFIA
amount to $46 billion in total financing costs.6 TIFIA typically provides financing to fill a gap in
a much larger financial package that sometimes involves private equity and private debt. For
example, the $2.6 billion IH-635 Managed Lanes project in Dallas, TX, is being financed with
$615 million in private activity bonds, a $664 million equity contribution from the private sector

partner, $17 million in toll revenues, $490 million in public funds, and an $850 million TIFIA
loan.7
WIFIA Pilot Program in S. 601
In the 113th Congress, House and Senate conferees have agreed to include a WIFIA pilot program
as part of H.R. 3080, the Water Resources Reform and Development Act of 2014 (WRRDA).8
Title X of Senate-passed S. 601 included a five-year pilot program, while House-passed H.R.
3080 included no similar provisions. Under the conference report on H.R. 3080, Title V, Subtitle
C, of the bill authorizes a five-year WIFIA pilot program. Under the bill, EPA would be
authorized to provide credit assistance (secured loans or loan guarantees) for drinking water and
wastewater projects, and the U.S. Army Corps of Engineers would be authorized to provide
similar assistance for water resource projects, such as flood control or hurricane and storm
damage reduction.
Under H.R. 3080, EPA and the Corps each would be authorized a total of $175 million over five
years (beginning with $20 million for each agency in FY2015 and increasing to $50 million in
FY2019) to provide assistance. Projects would have to be $20 million or larger in costs to be
eligible for credit assistance, except that projects in rural areas (population 25,000 or less) must
have eligible projects costs of $5 million or more. WIFIA credit assistance under H.R. 3080
would be available to project sponsors (a corporation; partnership; joint venture; trust; or a
federal, state, local, or tribal government) or to state infrastructure financing authorities for a
group of projects. In the case of projects carried out by a private entity, such projects are to be
publicly sponsored. To meet the requirement that a WIFIA-assisted project must be publicly
sponsored, the conference report allows a project applicant to demonstrate to the Corps or EPA
that the affected state, local, or tribal government supports the project. To ensure that ownership
of the water project does not become private (which would limit availability of some other
sources of federal financing), the maximum amount of a loan would be 49% of eligible project
costs, but the conference report would authorize EPA or the Corps to make available up to 25% of
available funds each year for credit assistance in excess of 49% of project costs. Except for
certain projects in rural areas, the total amount of federal assistance (i.e., WIFIA and other
sources) shall not exceed 80% of a project’s cost.
Activities eligible for assistance under H.R. 3080 would include project development and
planning, construction, acquisition of real property, and carrying costs during construction.
Categories eligible for assistance by the Army Corps would include flood control or hurricane and
storm damage reduction projects, environmental restoration, coastal or inland harbor navigation
improvement, or inland and intracoastal waterways navigation improvement. Categories eligible
for assistance by EPA would include projects at wastewater treatment and community drinking
water facilities, projects for enhanced energy efficiency of a public water system or wastewater
treatment works, repair or rehabilitation of aging wastewater and drinking water systems,
desalination or water recycling projects, or a combination of eligible projects. The Secretary of
the Army or EPA Administrator, as appropriate, would determine eligibility based on a project’s

project_profiles/tx_lbj635.htm.
8 A standalone measure to create a WIFIA program also has been introduced in the 113th Congress. S. 335 would
empower the Administrator of EPA to provide credit assistance to drinking water and wastewater infrastructure
projects.

creditworthiness and dedicated revenue sources for repayment. Selection criteria would include
the national or regional significance of the project, extent of public or private financing in
addition to WIFIA assistance, use of new or innovative approaches, the amount of budget
authority required to fund the WIFIA assistance, the extent to which a project serves regions with
significant energy development or production areas, and the extent to which a project serves
regions with significant water resources challenges.
Responding to concerns from some groups that WIFIA could impair and diminish support for
clean water and drinking water State Revolving Fund (SRF) programs under the Clean Water Act
and Safe Drinking Water Act (see discussion below), the conference report includes language
requiring the EPA Administrator, when the agency receives applications for WIFIA assistance, to
give state infrastructure financing authorities a right of “first refusal” to assist the project through
SRF monies.
WIFIA-assisted projects must use American-made iron and steel products (“Buy America”
provisions), and wastewater treatment works projects must comply with the prevailing wage
requirements of the Davis-Bacon Act, in the same manner that they would under the SRF
provisions of the Clean Water Act.
The conference report requires EPA and the Corps to provide information on an Internet website
concerning applications and projects that have received assistance, and it directs the Government
Accountability Office to report to Congress on the pilot programs in four years, along with
recommendations for continuing, changing, or terminating the WIFIA program.
Discussion
From the federal perspective, an advantage of TIFIA is that it can provide a large amount of credit
assistance relative to the amount of budget authority provided. The volume of loans and other
types of credit assistance that TIFIA can provide is determined by the size of congressional
appropriations and calculation of the subsidy cost.9 The subsidy cost largely determines the
amount of money that can be made available to project sponsors.10 DOT estimated that after
administrative costs and other deductions it would have $690 million for credit subsidy support in
FY2013 and $920 million in FY2014.11 Assuming an average subsidy cost of 10%, this could
provide DOT with the capacity to lend $6.9 billion in FY2013 and $9.2 billion in FY2014. If the
subsidy cost for water projects averages 10% and is the only charge against available budget
authority, a $20 million budgetary allocation theoretically supports $200 million in loans. In
budgetary terms, WIFIA (or TIFIA) assistance has much less of an impact than a water
infrastructure grant, which is not repaid to the U.S. Treasury.

9 According to the Federal Credit Reform Act of 1990, the subsidy cost is the “estimated long-term cost to the
Government of a direct loan or loan guarantee, calculated on a net present value basis, excluding administrative costs”
(104 Stat. 1388-610). The Federal Credit Reform Act of 1990 was enacted as part of the Omnibus Budget
Reconciliation Act of 1990 (P.L. 101-508).

Water Infrastructure Financing: Proposals to Create a WIFIA Program

Proponents of a WIFIA argue that loans for water projects could be even less risky than
transportation projects, because water rates are an established repayment mechanism, thus the
subsidy cost would be lower and the amount of credit assistance higher (per dollar of budget
authority).12 However, analysts note that, even with stable rate mechanisms, some communities
and water utilities have recently experienced problems with borrowing and bond repayments, so
repayment of a WIFIA loan is not a certainty.13
One of the main benefits of the TIFIA program is that it provides capital at a low cost to the
borrower, because even though the interest on 30-year Treasury securities is taxable, Treasury
rates can be less expensive than rates on traditional tax-exempt municipal debt. Moreover, TIFIA
financing is often characterized as patient capital, because loan repayment does not need to begin
until five years after substantial completion of a project, the loan can be for up to 35 years from
substantial completion, and the amortization schedule can be flexible. In addition, there is less
perceived investment risk, because the project has been determined to be creditworthy (i.e., there
is a revenue stream for repayment). The WIFIA legislation likewise is intended to provide these
benefits. As total TIFIA assistance cannot exceed 49% of project costs, it is intended to encourage
non-federal and private sector financing. H.R. 3080, with a similar 49% cap on assistance (and
limits on all sources of federal assistance to no more than 80% of project cost), would likely
encourage some non-federal financing, including from the private sector, but how much is
unclear.
Another possible benefit of a WIFIA program is that it is intended to not duplicate existing water
infrastructure financing tools. Many argue that the principal federal programs that assist local
wastewater and drinking projects—State Revolving Fund (SRF) programs under the Clean Water
Act and Safe Drinking Water Act—are useful primarily for smaller communities and smaller
projects.14 This might argue for expanding the SRF program, while keeping the WIFIA solely for
larger projects. Arguably, then, the $20 million minimum threshold for credit assistance contained
in H.R. 3080 could be about the right level so as not to duplicate assistance from SRFs.15 The
conference report, however, also provides access to WIFIA financing for smaller projects by
grouping, or aggregating, them through an SRF to meet the $20 million threshold, and it sets a
lower threshold ($5 million) for projects in rural areas. One possible downside of providing
smaller projects access to WIFIA financing, grouped or not, is the time and expense of
administering the program.
A major source of debate among opponents and proponents is potential adverse impacts of WIFIA
on funds for the Clean Water Act and Safe Drinking Water Act SRF programs. Several groups

Water Infrastructure Financing: Proposals to Create a WIFIA Program

representing state environmental officials opposed the WIFIA provisions of the 113th Congress
legislation because, they contend, it could result in reduced spending on the SRF programs, which
are capitalized by federal appropriations. States are concerned that WIFIA would likely be funded
at the detriment of the SRF programs.16 On the other hand, water utility groups argue that WIFIA
would complement, not harm, existing SRF programs. In their view, WIFIA will provide a new
funding opportunity for large water infrastructure projects that are unlikely to receive SRF
assistance.17 As described above, in part to address concerns about impacts of WIFIA on the SRF
programs, the conference report on H.R. 3080 would give state infrastructure financing
authorities a right of “first refusal” to provide SRF funds for a project when EPA receives an
application for WIFIA assistance.
A WIFIA program may shift some decision making for financing water infrastructure projects
from the state and local level to the federal level, specifically to the EPA or the Army Corps, a
change that concerns some stakeholders. Indeed, in a letter to the conferee managers, the
Administration expressed concerns with the WIFIA proposal in S. 601 during Senate
consideration of that bill, “which would expand the Environmental Protection Agency’s and the
Corps’ role in local water infrastructure projects and not provide Federal assistance in the most
efficient manner.”18
Another perceived benefit of the TIFIA program from the federal perspective is that it potentially
limits the federal government’s exposure to default by relying on market discipline through
creditworthiness standards and the encouragement of private capital investment. On the other
hand, the Congressional Budget Office (CBO) argues that the federal government underestimates
the cost of providing credit assistance under programs like TIFIA.19 This is because it excludes—
the cost of market risk—the compensation that investors require for the uncertainty of
expected but risky cash flows. The reason is that the FCRA [Federal Credit Reform Act]
requires analysts to calculate present values by discounting expected cash flows at the
interest rate on risk-free Treasury securities (the rate at which the government borrows
money). In contrast, private financial institutions use risk-adjusted discount rates to calculate
present values.20
Enacting a WIFIA program raises another federal budgetary and revenue issue. Legislation
reported by congressional committees typically is scored by the CBO for the effects on
discretionary and mandatory, or direct, spending and by the Joint Committee on Taxation (JCT)
for effects on revenue. The initial CBO cost estimate for S. 601, as approved by the Environment

and Public Works Committee in April 2013, concluded that the WIFIA provisions would cost
$260 million over five years. In addition, it would result in certain revenue loss to the U.S.
Treasury, thus, pay-as-you-go procedures would apply to the bill.21 CBO cited the JCT’s estimate
that enactment of the bill would reduce revenues by $135 million over 10 years, because states
would be expected to issue tax-exempt bonds in order to acquire additional funds not covered by
WIFIA assistance.22 To avoid the pay-as-you-go problem in the bill, the committee added a
provision to S. 601 to prohibit recipients of WIFIA assistance from issuing tax-exempt bonds for
the non-WIFIA portions of project costs. CBO re-estimated the bill and concluded that, because
the change would make the WIFIA program less attractive to entities, most of whom rely on tax-
exempt bonds for project financing, the cost of the bill would be $200 million less over five
years. CBO also said that the bill would have no impact on revenues, because the demand for
federal credit would be lower without the option of using tax-exempt financing.23 The conference
report on H.R. 3080 retains the bar on tax-exempt financing for WIFIA-assisted projects. Thus,
the apparent solution to one problem in the legislation—potential revenue loss—raises a different
kind of problem for entities seeking WIFIA credit assistance.
Conclusion
Most stakeholders in the debate about water infrastructure financing acknowledge that there is no
single solution or alternative that will fit all needs for all communities and all types of projects.
Most also recognize that financing, including approaches such as WIFIA, is not new revenue.
Investment via a particular financing tool, such as WIFIA, could simply displace existing
mechanisms, such as tax-exempt debt, rather than increase total investment in water
infrastructure. Whatever the source of funds for a project, communities and other sponsors must
still identify a stream of revenue to repay whatever debt is incurred for a given investment. One
of the challenges going forward is to ensure that financing is available for all needed projects.
