Walnut Cove WWTP - Secondary Treatment Plant in Walnut Cove, North Carolina

Walnut Cove WWTP is a municipal wastewater treatment facility located in Walnut Cove, Stokes County, North Carolina. The plant serves a population of approximately 1,516 residents, classifying it as a small-scale treatment facility under U.S. EPA guidelines. The plant provides secondary treatment, which is the minimum standard required by the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 1,892.70 units and currently discharges 340.69 units, indicating it operates well below its capacity. The treated effluent is discharged into a local water body, which ultimately drains into the Dan River basin and then into the Roanoke River, a major tributary of the Albemarle Sound. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, ensuring compliance with water quality standards to protect downstream ecosystems.

The plant discharges into a receiving water body within the Dan River watershed, which flows into the Roanoke River and eventually reaches the Albemarle Sound on the North Carolina coast. The downstream environment supports diverse aquatic life, including fish species such as striped bass and American shad, and provides important habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting water quality in this ecologically significant river system.
