Clean Water State Revolving Fund (CWSRF)


The New Mexico Environment Department manages the Clean Water State Revolving Loan Fund Program (CWSRF). The CWSRF program provides a source of low-cost financing for a wide range of wastewater and storm water projects that protect surface and ground water. Funds may also be used for projects that control non-point source water pollution, such as a solid waste and septic tank installations.

The CWSRF program was established in 1986 pursuant to the Wastewater Facility Construction Loan Act and the Federal Clean Water Act and provides low-interest loans with a repayment period of up to thirty years. Repayments are cycled back into the fund and used to pay for future clean water projects.
