The Vassar Wastewater Treatment Plant recycles wastewater that has been discharged into the City of Vassar's sanitary sewer system. The recycling process involves physical and biological processes that remove waste products from the water before it is discharged into the waters of the State of Michigan.

The City has been issued a permit to discharge clean, recycled water to the Cass River. The permit contains requirements for complying with State and Federal water pollution control laws. Wastewater Treatment Plant staff are responsible for complying with all permit requirements and to protect the environment to which we discharge water.
