Funding for All Communities
EPA Funding Sources
- Clean Water State Revolving Fund (CWSRF)
Funds water quality protection projects for centralized and decentralized wastewater treatment, nonpoint source pollution control, and watershed and estuary management. The CWSRF uses federal, state, and other program funds to provide low-interest loans to communities for water quality projects. States may customize loan terms to meet the needs of small, disadvantaged communities, which typically have fewer financing options. - Drinking Water State Revolving Fund (DWSRF)
Funds infrastructure improvements in drinking water systems. The DWSRF emphasizes funding to small and economically disadvantaged communities and other programs that encourage preventing pollution to drinking water. - Environmental Justice Grants and Cooperative Agreements
Provide financial assistance to eligible organizations to develop collaborative partnerships, identify environmental and public health issues, and develop projects. - Nonpoint Source Grants Program (Section 319 of the Clean Water Act)
Provides grants for activities that prevent water pollution from nonpoint sources, including education, training, technical and financial assistance, technology transfer, demonstration projects, and monitoring nonpoint source implementation projects. Eligible projects include decentralized wastewater systems. - Public Water System Supervision (PWSS) Grant Program
Assists states, territories, and tribes to develop and implement PWSS programs to enforce the requirements of the Safe Drinking Water Act. - Water Pollution Control Grants Program (Section 106 of the Clean Water Act)
Provides federal assistance to states, territories, the District of Columbia, Indian tribes, and interstate agencies to establish and implement ongoing water pollution control programs.
