Clinton Collection Sys Wastewater Treatment Plant - Clinton, South Carolina

Clinton Collection Sys is a municipal wastewater treatment facility located in Clinton, Laurens County, South Carolina. The plant serves a population of roughly 7,788 people, placing it in the small-to-medium agglomeration category for US inland communities. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US Clean Water Act. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) or additional filtration, ensuring high-quality effluent before discharge. As a US facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the South Carolina Department of Health and Environmental Control, which sets specific effluent limits and monitoring requirements. The treated wastewater is discharged into a local waterway within the Santee River basin, which ultimately flows to the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Santee River and its associated wetlands, which support diverse fish and wildlife populations.

The plant discharges into a tributary of the Santee River system, which drains into the Atlantic Ocean via the Santee Delta. This watershed supports a variety of aquatic species and provides important habitat for migratory fish. Advanced treatment at this facility reduces nutrient loading, helping to prevent eutrophication in downstream waters.
