Jefferson Co Mellwood Acres WWTP - Advanced Treatment in Taylortown, Ohio

Jefferson Co Mellwood Acres WWTP is a wastewater treatment facility located in Taylortown, Jefferson County, Ohio, United States. The plant serves a small population of 120 residents, reflecting its role as a local-scale treatment facility in a rural or suburban setting. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 113.56 megaliters per year and a discharge volume matching that figure, the facility operates at full capacity. Under the US Clean Water Act, such plants are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Ohio River basin. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps minimize nutrient loading and protect downstream ecosystems.

The plant discharges into the Ohio River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The watershed supports diverse aquatic species and is an important migratory corridor for birds. Advanced treatment reduces nutrient pollution, helping to mitigate hypoxia in the Gulf of Mexico.
