Sardinia WWTP and Sewer System - Advanced Treatment Plant in Sardinia, Ohio

Sardinia WWTP and Sewer System is a municipal wastewater treatment facility located in Sardinia, Ohio, within Brown County. The plant serves a population of approximately 1,220 residents, providing essential sanitation services to this small community. As part of Ohio's wastewater infrastructure, it plays a key role in managing local sewage and protecting public health. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,135.62 cubic meters per day and a current discharge volume of 567.81 cubic meters per day, the facility operates under the regulatory framework of the U.S. Clean Water Act. This framework requires National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to safeguard water quality. The treated effluent is discharged into a nearby water body that 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 reduce nutrient loading and protects downstream ecosystems, including the Mississippi River Delta and the Gulf of Mexico.

The plant discharges into local streams that flow into the Ohio River, a major tributary of the Mississippi River system. The Ohio River basin supports diverse aquatic habitats and is an important migratory corridor for fish and birds. Advanced treatment at this facility helps minimize nutrient pollution, which can cause algal blooms and hypoxic zones in downstream waters, including the Gulf of Mexico.
