The plant discharges treated effluent to McDowell Creek, which flows into the Catawba River basin. The Catawba River is a major waterway in the Carolinas, ultimately draining into Lake Wateree and the Santee River system before reaching the Atlantic Ocean. The plant plays a key role in protecting water quality in this ecologically important watershed.
