The plant's treated effluent is discharged into a local waterway that drains into the Grand River, which flows westward to Lake Michigan. This watershed supports diverse aquatic life and provides recreational and ecological benefits to the region. The plant plays a key role in protecting water quality in the Grand River basin and downstream Lake Michigan ecosystem.
