DALLAS WWTP - Advanced Wastewater Treatment in Dallas, North Carolina

DALLAS WWTP is a municipal wastewater treatment plant located at 621 East Holly Street in Dallas, Gaston County, North Carolina. The facility serves a population of approximately 3,980 residents, classifying it as a small-scale treatment operation within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,271.24 thousand cubic meters per year and an actual discharge volume of 946.35 thousand cubic meters, the plant operates well within its capacity. As a US facility, it operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, administered by the North Carolina Department of Environmental Quality. The treated effluent is discharged into local waterways that ultimately drain into the Catawba River basin, which flows through the Carolinas before reaching the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into the Catawba River basin, a major watershed in the southeastern United States that provides drinking water and supports diverse aquatic life. The river flows through North and South Carolina before emptying into the Atlantic Ocean via Winyah Bay. Advanced treatment at this facility helps reduce nutrient loading, which is critical for preventing algal blooms and maintaining healthy downstream habitats.
