The Drinking Water State Revolving Fund (DWSRF) is a State-operated program that provides financial assistance to Maine public water systems, helping to ensure safe drinking water and provide essential public health protection. Funding for drinking water infrastructure improvement projects -- upgrading or replacing water system pipes, treatment plants, storage tanks, and sources of water -- is available as low interest loans. Disadvantaged Community Water Systems may receive further assistance through principal forgiveness.
Federal allocations for the fund were included in the 1996 amendments to the SDWA, while states match 20% of Federal grant dollars. This means that every dollar invested by the State of Maine secures five Federal dollars.
A portion of the DWSRF is used to fund non-construction projects that help improve and protect drinking water quality in Maine. These programs provide funds for source water protection, technical assistance, system capacity development assistance, and land acquisition.
The Maine Department of Health and Human Services and the Maine Municipal Bond Bank (MMBB) administer the DWSRF together. The Drinking Water Program is the Lead Administrator and is responsible for project management and technical support, as well as overseeing activities. The MMBB is the Financial Administrator and oversees the loan application process and tracks money to and from the fund.
A portion of the federal grant is set aside each year from the revolving project loan fund and used for non-project activities. Those activities include source water protection programs, technical assistance to small systems, a revolving loan fund for land acquisitions, system planning grants and wellhead protection grants.
