Niles Wastewater Treat Pl - Niles, Michigan Municipal Wastewater Treatment

Niles Wastewater Treat Pl is a municipal wastewater treatment facility located in Niles, Michigan, along the St. Joseph River. The plant serves a population of about 26,459 residents in the Niles area, which is part of Berrien County in southwestern Michigan. As a facility serving a medium-sized agglomeration, it operates under the U.S. Clean Water Act, which requires secondary treatment as a minimum standard for municipal wastewater plants. The plant has a designed capacity of 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flow. The treated effluent is discharged into the St. Joseph River, which flows westward into Lake Michigan, a vital freshwater resource and part of the Great Lakes system. The plant plays a key role in protecting water quality in the St. Joseph River watershed and downstream Lake Michigan ecosystems.

The plant discharges into the St. Joseph River, which flows approximately 210 miles through Michigan and Indiana before entering Lake Michigan near Benton Harbor. Lake Michigan is the second-largest Great Lake by volume and supports diverse aquatic life, including fish species such as lake trout and whitefish. The watershed is primarily agricultural and urban, so the plant helps reduce nutrient and pathogen loads that could otherwise contribute to eutrophication and beach closures in Lake Michigan.
