South Charleston WWTP and Sewers - Advanced Treatment Facility in Ohio

South Charleston WWTP and Sewers is a municipal wastewater treatment facility located in South Charleston, Clark County, Ohio, United States. The plant serves a population of approximately 1,850 residents, providing essential sanitation services for this small community in the Midwestern state. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 908.50 million gallons per year and an actual discharge volume of 719.23 million gallons, the plant operates below its capacity. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Ohio Environmental Protection Agency. The treated effluent is discharged into a local receiving water body, which ultimately drains into the Ohio River basin. The Ohio River flows into the Mississippi River and then to the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into a local stream that is part of the Ohio River watershed. The Ohio River flows into the Mississippi River, which empties into the Gulf of Mexico. The plant's advanced treatment reduces nutrient loading, helping to mitigate hypoxia in the Gulf and protect local aquatic life in the receiving waters.
