SEABOARD WWTP - Seaboard, North Carolina Wastewater Treatment Plant

SEABOARD WWTP is a municipal wastewater treatment facility located in Seaboard, North Carolina, a small town in Northampton County. The plant serves a population of 616 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. Plants of this scale typically have permits issued by the North Carolina Department of Environmental Quality. The designed capacity is 507.24 million gallons per year, with an actual discharge volume of 227.13 million gallons per year, indicating operational capacity below design. The treated effluent is discharged into a local waterway that ultimately drains into the Roanoke River basin, which flows into Albemarle Sound and the Atlantic Ocean. The plant plays a key role in protecting local water quality and downstream ecosystems, including the Albemarle-Pamlico estuarine system, which supports diverse aquatic life and important fisheries.

The plant discharges into a tributary of the Roanoke River, which flows into Albemarle Sound, a large estuary on the North Carolina coast. Albemarle Sound is part of the Albemarle-Pamlico estuarine system, one of the largest estuarine systems in the United States, supporting critical habitats for fish, shellfish, and migratory birds. The secondary treatment provided by the plant helps reduce nutrient and pollutant loads, protecting downstream water quality and ecological health.
