Scioto Co Briarcliff Complex WWTP, Portsmouth, Ohio: Advanced Wastewater Treatment

Scioto Co Briarcliff Complex WWTP is a municipal wastewater treatment facility located in Portsmouth, Ohio, United States. The plant serves a small population of 195 residents within Scioto County, operating as part of the local wastewater infrastructure. The facility provides advanced treatment, which goes beyond the secondary treatment standard required by the U.S. Clean Water Act. With a designed capacity of 151.42 megaliters per year and an annual discharge volume of 68.14 megaliters, the plant operates well within its capacity. As a small-scale plant, it is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local receiving water body that ultimately drains into the Ohio River watershed. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps minimize nutrient and pollutant loads to these downstream waters.

The plant discharges into a water body within the Ohio River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Advanced treatment at this facility reduces the risk of eutrophication and protects downstream aquatic habitats.
