Little River S T P - Laurens, South Carolina Wastewater Treatment Plant

Little River S T P is a municipal wastewater treatment facility located in Laurens, South Carolina, serving a population of about 18,000. The plant is situated inland, over 50 km from the coast, and discharges into local waterways that ultimately drain to the Atlantic Ocean. As a facility serving a medium-sized agglomeration, the plant is expected to meet secondary treatment standards under the U.S. Clean Water Act. NPDES permits, administered by the South Carolina Department of Health and Environmental Control, govern discharge limits and monitoring requirements to protect water quality. The treated effluent enters the Little River watershed, a tributary of the Saluda River, which flows into Lake Greenwood and then the Congaree River. This river system supports diverse aquatic life and provides drinking water and recreation for downstream communities.

The plant discharges into the Little River, a tributary of the Saluda River, which flows into Lake Greenwood and eventually the Congaree River. This watershed is part of the larger Santee River basin, draining to the Atlantic Ocean. The area supports diverse aquatic species and is used for fishing and recreation, making effluent quality important for ecosystem health.
