Silver Creek POTW - Secondary Wastewater Treatment Plant in Silver Creek, Mississippi

Silver Creek POTW (Publicly Owned Treatment Works) is a municipal wastewater treatment facility located in Silver Creek, Lawrence County, Mississippi. The plant serves a small population of 360 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, which typically involves biological processes to remove organic matter and suspended solids. It has a designed capacity of 113.56 million gallons per year and reports an annual discharge volume of 151.42 million gallons, indicating operation above design capacity. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting administered by the Mississippi Department of Environmental Quality. The treated effluent is discharged into local waterways that ultimately drain into the Pearl River basin and then to the Gulf of Mexico. The plant plays a role in protecting water quality in the region, supporting downstream aquatic ecosystems and recreational uses.

The plant discharges into receiving waters within the Pearl River watershed, which flows south through Mississippi and Louisiana before emptying into the Gulf of Mexico. This region supports diverse aquatic life, including fish and freshwater mussels, and the river provides habitat for migratory birds. The Gulf Coast downstream is ecologically sensitive, with estuaries that rely on balanced freshwater inflows.
