Shallotte WWTP is a municipal wastewater treatment plant located in Shallotte, Brunswick County, North Carolina. It serves a population of approximately 1,643 residents, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant is situated near the coast, reflecting the region's coastal plain geography. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional nutrients and contaminants. This level of treatment is typical for facilities discharging into sensitive environments. The plant has a designed capacity of 2,081.97 thousand gallons per day and currently handles an average daily flow of 529.96 thousand gallons per day, indicating ample reserve capacity. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent from Shallotte WWTP is discharged into local waterways that ultimately drain to the Atlantic Ocean via the coastal river systems of southeastern North Carolina. The plant's advanced treatment helps protect downstream estuarine and marine habitats, which support diverse aquatic life and are important for local fisheries and recreation.

Shallotte WWTP discharges into the Shallotte River basin, which flows into the Atlantic Intracoastal Waterway and then to the Atlantic Ocean. The coastal waters in this region support estuarine habitats, including salt marshes and tidal creeks, which are critical nursery grounds for fish and shellfish. The advanced treatment level helps minimize nutrient loading and protects these sensitive ecosystems from eutrophication.
