Scio WWTP and Sewer System is a municipal wastewater treatment facility located in Scio, a village in Harrison County, Ohio, United States. The plant serves a population of approximately 799 residents, reflecting its role in a small rural community. It operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the Clean Water Act for municipal facilities. Advanced treatment typically includes nutrient removal or other processes to meet stringent water quality standards. The plant has a designed capacity of 757.08 m³/day and currently treats an average daily flow of 302.83 m³/day, indicating operational capacity well within design limits. The treated effluent is discharged to a local receiving water body, likely a stream or river within the Ohio River basin. The Ohio River watershed supports diverse aquatic life and provides drinking water for millions. The plant's advanced treatment helps protect downstream water quality and ecological health in this important regional drainage system.

The plant discharges into a local water body that is part of the Ohio River basin, which ultimately drains to the Mississippi River and the Gulf of Mexico. The Ohio River watershed supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing eutrophication in downstream waters.
