South Bloomfield WWTP and Sewers | Advanced Treatment Plant in Ohio

South Bloomfield WWTP and Sewers is a municipal wastewater treatment facility located in South Bloomfield, Pickaway County, Ohio. The plant serves a population of 1,754 and operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. As an advanced treatment plant, it provides a higher level of pollutant removal than secondary treatment, ensuring compliance with stringent water quality standards. The plant's designed capacity is 1,892.70 thousand gallons per day, with an actual discharge volume of 946.35 thousand gallons per day, indicating it operates well below capacity. Advanced treatment typically includes nutrient removal and disinfection. The facility is overseen by the Ohio Environmental Protection Agency, which issues permits and enforces discharge limits to protect local water bodies. The treated effluent is discharged into a receiving water body within the Scioto River watershed, which flows into the Ohio River and ultimately the Mississippi River and Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Scioto River basin, which is home to diverse fish and macroinvertebrate communities.

The plant discharges into a tributary of the Scioto River, which flows south to the Ohio River, a major tributary of the Mississippi River. The Scioto River watershed supports diverse aquatic life, including several species of freshwater mussels and fish. Advanced treatment at this facility reduces nutrient loads, helping to prevent eutrophication in downstream waters, including the Gulf of Mexico hypoxic zone.
