The plant's treated effluent is discharged into local waterways that ultimately drain into the Catawba River basin. The Catawba River flows through the Piedmont region of North Carolina and South Carolina, eventually reaching Lake Wateree and the Santee River system, which empties into the Atlantic Ocean. The watershed supports diverse aquatic life and provides drinking water for downstream communities.

The plant discharges into the Catawba River basin, which flows through the Piedmont region and into Lake Wateree in South Carolina. The Catawba River is a major water source for the region, supporting fish populations and recreational activities. Downstream, the river connects to the Santee River system, which drains into the Atlantic Ocean, making nutrient management important to prevent eutrophication in coastal waters.
