Michigan’s Clean Water State Revolving Fund (CWSRF) program is a low interest loan financing program that assists qualified local municipalities with the construction of necessary wastewater and storm water infrastructure projects. These projects improve water quality, the environment, and protect public health. Michigan’s CWSRF program has allocated over $5.7 billion in low interest loans to over 670 projects around the State since 1988. Of that amount, $106 million has been awarded as loan principal forgiveness since 2010. For more information on the CWSRF program, view the CWSRF Info Sheet.
