McAdenville WWTP - Secondary Treatment Plant in McAdenville, North Carolina

McAdenville WWTP is a municipal wastewater treatment facility located on Church Street in McAdenville, Gaston County, North Carolina. The plant serves a small population of 870 residents, reflecting the scale of this community in the Piedmont region of the state. The plant provides secondary treatment, a standard level required by the US Clean Water Act for municipal facilities. With a designed capacity of 492.10 thousand gallons per day and an average discharge volume of 465.61 thousand gallons per day, the plant operates near its capacity. As a US facility, it operates under an NPDES permit issued by the North Carolina Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent is discharged into a receiving water body that ultimately drains into the Catawba River basin, a major watershed in the Carolinas. The Catawba River flows into Lake Wylie and then continues to the Atlantic Ocean via the Santee River system. The plant's operations help protect local water quality and downstream ecosystems.

The plant discharges into a tributary of the Catawba River, which flows through the Piedmont region into Lake Wylie, a reservoir on the North Carolina-South Carolina border. The Catawba River basin supports diverse aquatic life, including several fish species and migratory birds. Downstream, the river joins the Santee River system, eventually reaching the Atlantic Ocean. The plant's secondary treatment helps reduce nutrient and organic loads, protecting the ecological health of this important watershed.
