Drinking Water State Revolving Fund


Provide $2.32 billion in funding for Fiscal Year 2022.


Established in 1996, the Drinking Water State Revolving Fund (DWSRF) is a state-federal partnership that provides low-interest loans to improve drinking water treatment, fix leaking or old pipes, improve the source of water supply, replace or construct finished water storage tanks, and other water infrastructure projects to protect public health including all forms of water reuse. Publicly-owned, privately-owned and not-for-profit community utilities are eligible for funding.

The U.S. Environmental Protection Agency allocates funding to states who administer the program. States contribute an additional 20% in matching funds and many leverage federal dollars using financing tools, such as bonds, to provide additional funding for projects. Loan repayments are used to support new projects, hence the revolving nature of the program.


  • Communities can leverage federal funding to finance needed water infrastructure.
  • Low-interest loans create a recurring source of funding for critical infrastructure.
