North Carrollton POTW - Secondary Wastewater Treatment in Carrollton, Mississippi

North Carrollton POTW is a publicly owned treatment works serving the community of Carrollton, Mississippi, in Carroll County. The plant provides secondary treatment for a population of 675, operating under the U.S. Clean Water Act framework. As a secondary treatment facility, North Carrollton POTW uses biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 227.12 thousand cubic meters per year and currently discharges 264.98 thousand cubic meters annually, indicating operation near or at capacity. Under the National Pollutant Discharge Elimination System (NPDES), the plant must meet effluent limits set by the Mississippi Department of Environmental Quality. The treated effluent is discharged into a local waterway that ultimately drains into the Yazoo River basin, part of the larger Mississippi River watershed. This system supports diverse aquatic life and provides water for agricultural and recreational uses downstream. The plant's location inland reduces direct marine impact, but its discharge contributes to the overall water quality of the region's river systems.

The plant discharges into a tributary of the Yazoo River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Yazoo River basin supports a variety of fish and wildlife, including several species of freshwater mussels and migratory birds. Maintaining secondary treatment standards helps protect downstream water quality in this ecologically significant watershed.
