CLIO WWTP - Advanced Wastewater Treatment in Five Forks, South Carolina

CLIO WWTP is a municipal wastewater treatment facility located in Five Forks, Marlboro County, South Carolina. Serving a population of 1,625, the plant provides advanced treatment to protect local water quality. The facility is situated inland, away from coastal zones, and operates under the regulatory framework of the U.S. Clean Water Act. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a discharge volume of 677.59 units, the facility is designed to meet stringent effluent limits set by its National Pollutant Discharge Elimination System (NPDES) permit. Such permits are issued by the South Carolina Department of Health and Environmental Control to ensure compliance with federal standards. The treated effluent from CLIO WWTP is discharged into a local water body that ultimately drains into the Pee Dee River basin. This river system flows through the coastal plain of South Carolina before reaching the Atlantic Ocean. The advanced treatment helps protect downstream aquatic habitats and supports the ecological health of the watershed.

CLIO WWTP discharges into a tributary of the Pee Dee River, which flows through the coastal plain of South Carolina and empties into Winyah Bay and the Atlantic Ocean. The Pee Dee basin supports diverse aquatic life, including fish and migratory species. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream estuaries.
