Potterville WWTP is an advanced wastewater treatment facility located in Potterville, Michigan, serving a population of approximately 1,523 residents. The plant is situated in Eaton County and is part of the municipal infrastructure for the community. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 757.08 megaliters per year and an actual discharge volume of 567.81 megaliters, the plant operates below its capacity. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The treated effluent is discharged into local waterways that ultimately drain into the Grand River watershed and then into Lake Michigan. This connection to the Great Lakes system underscores the importance of advanced treatment in protecting water quality and aquatic ecosystems downstream.

The plant discharges into the Grand River basin, which flows into Lake Michigan, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. Advanced treatment helps reduce nutrient loading, which is critical to preventing algal blooms in the Great Lakes.
