Mandela WWTP, New Roads, Louisiana | Small Community Wastewater Treatment

Mandela WWTP is a municipal wastewater treatment facility located on Mandela Drive in New Roads, Louisiana, within Pointe Coupee Parish. The plant serves a small population of approximately 250 residents, reflecting its role as a local infrastructure asset for this rural community in the southeastern United States. The facility provides secondary treatment, which is the standard biological treatment process required under the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 132.49 volume units and a corresponding discharge volume, the plant is sized to meet the needs of its small service area. Operations are subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality, ensuring compliance with federal and state water quality standards. The treated effluent from Mandela WWTP is discharged into nearby surface waters that ultimately drain into the Lower Mississippi River basin. This region is ecologically significant, supporting diverse aquatic life and contributing to the health of the Mississippi River Delta and the Gulf of Mexico. The plant's secondary treatment helps reduce nutrient loads and protect downstream water quality.

The plant discharges into local streams that flow into the Lower Mississippi River, which empties into the Gulf of Mexico. This watershed supports a variety of fish and wildlife, and the Mississippi River Delta is an important ecological zone. Secondary treatment helps mitigate nutrient pollution, which is critical for preventing hypoxic zones in the Gulf.
