The plant discharges into the Catawba River basin, a major watershed in the southeastern United States. The Catawba River flows through North Carolina and South Carolina, providing drinking water, recreation, and habitat for diverse aquatic species. Downstream, the river feeds into Lake Wateree and eventually the Santee River, which empties into the Atlantic Ocean. The plant's advanced treatment helps minimize nutrient and pollutant loads, protecting sensitive aquatic habitats and supporting the ecological health of the basin.
