CLINTON STP Wastewater Treatment Plant, Clinton Township, Michigan

CLINTON STP is a municipal wastewater treatment facility located in Clinton Township, Lenawee County, Michigan. The plant serves a small community of 1,669 residents and operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 1,608.80 million gallons per year and an actual discharge volume of 984.21 million gallons per year, the facility operates below its maximum capacity, indicating room for future growth or seasonal variability. The treated effluent from CLINTON STP is discharged into a local water body, which ultimately drains into the Lake Erie basin via the Maumee River or the Raisin River system. Lake Erie is a vital freshwater resource that supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps protect downstream water quality in this ecologically sensitive Great Lakes watershed.

CLINTON STP discharges into a tributary of the Lake Erie basin, a major freshwater ecosystem that supports diverse fish populations and migratory birds. The plant's advanced treatment reduces nutrient loading, which is critical for preventing harmful algal blooms in Lake Erie. The watershed is part of the Great Lakes system, the largest surface freshwater system in the world, and is subject to bi-national water quality agreements between the United States and Canada.
