Funding Sources for Small and Rural Wastewater Systems

EPA and other organizations provide funding to improve water and wastewater systems in small and rural communities.

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.

Funding for U.S.-Mexico Border Communities

  • U.S.-Mexico Border Water Infrastructure Grant Program
    Provides grant assistance to communities along the U.S.-Mexico border for planning, designing, and constructing drinking water and wastewater infrastructure. The U.S.-Mexico border region is defined as 100 kilometers (62 miles) north and 100 kilometers south of the U.S.-Mexico border. EPA's grant program supports the Project Development Assistance Program, administered by the Border Environment Cooperation Commission, and the Border Environmental Infrastructure Fund, administered by the North American Development Bank. 
  • U.S.-Mexico Border 2020 Program
    The latest environmental program implemented under the 1983 La Paz Agreement. The program emphasizes regional, bottom-up approaches for decision-making, priority setting, and project implementation to address environmental and public health problems in the border region. The program encourages participation from communities and local stakeholders.
