PLYMOUTH WWTP - Plymouth, Indiana Wastewater Treatment Plant

PLYMOUTH WWTP is a municipal wastewater treatment facility located in Plymouth, Marshall County, Indiana. Serving a population of around 10,033, the plant is part of the city's infrastructure for managing domestic and industrial wastewater. As a medium-sized agglomeration, it 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. Facilities of this scale in Indiana typically employ secondary treatment to meet state and federal standards. The Indiana Department of Environmental Management (IDEM) oversees compliance with effluent limits designed to protect receiving waters. The plant's discharge likely undergoes biological treatment and disinfection before release. The treated effluent from PLYMOUTH WWTP flows into the Yellow River, a tributary of the Kankakee River, which eventually drains into the Illinois River and then the Mississippi River. This watershed supports diverse aquatic life and is important for regional water quality. The plant's operations help maintain the ecological health of these downstream water bodies.
