Southeast Brunswick SD WWTP - Advanced Treatment Plant in St. James, North Carolina

Southeast Brunswick SD WWTP is a municipal wastewater treatment facility located in St. James, Brunswick County, North Carolina. The plant serves a population of approximately 4,238 residents and operates under the regulatory framework of the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 7,570.80 units, and it currently discharges 851.72 units, indicating significant reserve capacity for future growth. As a coastal facility within 10 km of the Atlantic Ocean, the plant must meet stringent effluent limits to protect sensitive estuarine and marine environments. The treated effluent is discharged into local waterways that drain to the Atlantic Ocean via the Cape Fear River basin or nearby coastal estuaries. The region supports diverse aquatic life, including fish, shellfish, and migratory birds, making proper wastewater treatment critical for maintaining water quality and ecosystem health.

The plant discharges into the Cape Fear River basin, which flows into the Atlantic Ocean near the southeastern coast of North Carolina. This coastal region includes ecologically sensitive estuaries and salt marshes that support diverse marine life, including shrimp, crabs, and fish. Advanced treatment helps reduce nutrient loading, which can cause algal blooms and hypoxia in downstream waters.
