Hayesville WWTP and Sewer System - Advanced Treatment Plant in Ohio

Hayesville WWTP and Sewer System is a municipal wastewater treatment facility located in Hayesville, Ohio, United States. The plant serves a small population of 348 residents and operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. 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 227.12 megaliters, with an actual discharge volume of 151.42 megaliters, indicating operational capacity below design levels. Advanced treatment typically includes nutrient removal, filtration, or disinfection beyond secondary treatment. The plant is located inland, more than 50 kilometers from the coast, reducing direct marine impact. The treated effluent is discharged into a local water body, likely a tributary of the Ohio River basin, which ultimately drains into the Mississippi River and 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 within the Ohio River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream waters.
