The treated effluent from Branchville WWTP is discharged into local streams that are part of the Edisto River basin. The Edisto River is one of the longest free-flowing blackwater rivers in the eastern United States, supporting diverse aquatic life including fish, amphibians, and freshwater mussels. The river ultimately drains into the Atlantic Ocean near Edisto Beach, South Carolina.

The plant discharges into tributaries of the Edisto River, a blackwater river system that flows through the coastal plain of South Carolina. The Edisto River supports a variety of fish species and provides habitat for freshwater mussels and other aquatic organisms. The river's blackwater characteristics, caused by tannins from decaying vegetation, create a unique ecosystem. Downstream, the river empties into the Atlantic Ocean, contributing to estuarine habitats along the coast.
