Federal funding to assist communities with capital projects to meet the water-related goals and requirements of federal laws has been provided through programs in the Clean Water Act (CWA) and the Safe Drinking Water Act. This report provides a table showing budget requests and appropriations for the Environmental Protection Agency's (EPA's) water infrastructure assistance programs under these two laws since 1973.

The Water Pollution Control Act of 1948 (P.L. 80-845) established a grant program to assist localities with planning and design work and authorized loans for treatment plant construction. In subsequent amendments, federal assistance increased and a construction grant program replaced the loan program. In the Federal Water Pollution Control Act Amendments of 1972 (P.L. 92-500, popularly known as the Clean Water Act), Congress established the first national standards for sewage treatment and significantly increased federal funding to help communities meet the law's standards.

Congress enacted the most recent comprehensive CWA amendments in 1987 (P.L. 100-4). That legislation authorized $18 billion over nine years for wastewater treatment plant construction, through a combination of the traditional Title II grant program and a new State Water Pollution Control Revolving Funds (SRF) program.¹ Using SRF program appropriations, EPA provides federal capitalization grants as seed money for state-administered loans to construct sewage treatment plants and other water quality projects. Local communities, in turn, repay loans to the state, not the federal government. Pursuant to the 1987 amendments, the SRF program started in FY1989 and entirely replaced the previous grant program in FY1991.

In 1996 Congress amended the Safe Drinking Water Act (P.L. 104-182) to authorize a drinking water state revolving loan fund (DWSRF) program to help systems finance projects needed to comply with drinking water regulations and to protect public health.² This program, which parallels the Clean Water Act SRF, authorizes EPA to make grants to states to capitalize DWSRFs, which states then use to make loans to public water systems. The legislation authorized a total of $9.6 billion over 10 years to assist drinking water projects. The America's Water Infrastructure Act of 2018 (P.L. 115-270), enacted October 23, 2018, provided authority for appropriations for FY2019 through FY2021.

Table 1 shows the appropriations data for the wastewater and drinking water SRF programs from FY1973 through FY2019 in nominal dollars and real dollars (i.e., not adjusted for inflation). Since 1973, Congress has provided more than $121 billion for these programs.

Table 1 also shows appropriations for special projects. These are funds designated in appropriations legislation for projects in specified communities or locations, often referred to as "earmarks." Because some Members of Congress, interest groups, and Administration officials criticize these types of congressional actions, Congress banned the practice of congressionally designated special project funds for EPA's water infrastructure and other programs in FY2011. Amounts shown in the table for special projects appropriations are predominantly congressionally directed funds, but they also include amounts requested by the Administration since the early 1990s for a limited number of special projects (e.g., in certain coastal communities, for Alaska Native and rural villages, and for U.S.-Mexico Border projects that Congress has continued to fund).³

In addition, Table 1 identifies appropriations for the Water Infrastructure Finance and Innovation Act (WIFIA) program.⁴ WIFIA provides another source of potential funding for water infrastructure. Congress established the WIFIA program in the Water Resources Reform and Development Act of 2014 (WRRDA; P.L. 113-121). The act, among other provisions, authorizes EPA to provide credit assistance (e.g., secured/direct loans) for a range of wastewater and drinking water projects. Project costs must be $20 million or larger to be eligible for credit assistance. In rural areas (defined as populations of 25,000 or less), project costs must be $5 million or more.

In 2018, EPA issued its first WIFIA loan.⁵ For FY2019, Congress (P.L. 116-6) provided $60 million for loan subsidy costs (and $8 million for administrative costs), which may be used to provide up to $7.3 billion in credit assistance for water infrastructure projects.

For comparison, Figure 1 shows total EPA water infrastructure appropriations (for clean water and drinking water assistance combined) over the same period in both nominal dollars and constant (2017) dollars.
