Mount Sterling WWTP and Sewer System - Ohio Wastewater Treatment Plant

The Mount Sterling WWTP and Sewer System is a municipal wastewater treatment facility located in Mount Sterling, Ohio, a small village in Madison County. The plant serves a population of about 1,865 people, reflecting the scale of a small community in the Midwestern United States. As a facility serving fewer than 2,000 people, it falls under the regulatory framework of the U.S. Clean Water Act, administered through the National Pollutant Discharge Elimination System (NPDES) permit program. The Ohio Environmental Protection Agency (Ohio EPA) typically issues permits for such plants, setting effluent limits to protect water quality. Plants of this size commonly employ secondary treatment technologies such as activated sludge or lagoon systems to meet permit requirements. The treated effluent from the plant is discharged into a local stream that flows into the Scioto River, which ultimately drains into the Ohio River and then the Mississippi River. The Scioto River watershed supports diverse aquatic life and is an important ecological corridor in central Ohio. The plant's operations help protect downstream water quality and recreational uses in the region.

The Mount Sterling WWTP discharges into a tributary of the Scioto River, which flows southward to join the Ohio River. The Scioto River basin supports a variety of fish and macroinvertebrate species and provides habitat for migratory birds. The plant's effluent contributes to the base flow of local streams, and its treatment performance is critical to maintaining water quality standards in this agriculturally influenced watershed.
