Macclesfield WWTP - Advanced Wastewater Treatment in Macclesfield, North Carolina

Macclesfield WWTP is an advanced wastewater treatment facility located in Macclesfield, North Carolina, United States. Serving a population of 576, the plant is part of the municipal infrastructure for this small community in Edgecombe County. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 662.45 megaliters and an annual discharge volume of 151.42 megaliters, the facility operates well below its capacity. Under the US Clean Water Act, such facilities are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the state of North Carolina, ensuring compliance with water quality standards. The treated effluent from Macclesfield WWTP is discharged into local waterways that ultimately drain into the Tar River basin, which flows into the Pamlico Sound and the Atlantic Ocean. The plant plays a key role in protecting downstream aquatic ecosystems, including the ecologically sensitive Pamlico Sound estuary, by reducing pollutant loads from the community.

The plant discharges into the Tar River watershed, which flows into the Pamlico Sound, a large estuary along the North Carolina coast. The Pamlico Sound supports diverse aquatic life, including fish, shellfish, and migratory birds. Advanced treatment at the plant helps minimize nutrient pollution, which is critical for preventing algal blooms and maintaining water quality in this ecologically important estuary.
