Clean Water State Revolving Fund (SRF) and Wetlands
In 1987, Congress amended the Clean Water Act and created the Clean Water State Revolving Fund (CWSRF) to finance projects that improve water quality. The 51 individual revolving funds combine federal and state money to provide low-interest loans for eligible projects. More than $5 billion is provided annually to public and private organizations to improve water quality. As the loans are repaid, money is available to be used again for new projects — a true revolving fund. Wetland preservation, restoration and creation projects are often eligible for funding under the CWSRF.
