New Roads Lagoon Wastewater Treatment Plant, New Roads, Louisiana

New Roads Lagoon is a municipal wastewater treatment facility located in New Roads, Pointe Coupee Parish, Louisiana. The plant serves a population of approximately 5,300 residents, classifying it as a small to medium-sized community system. It is situated in the southeastern United States, near the Mississippi River floodplain. As a lagoon-based system, the plant likely provides secondary treatment through natural biological processes, which is typical for small communities in Louisiana. Under the US Clean Water Act, such facilities must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality, ensuring effluent meets state water quality standards. The plant's treated effluent discharges into local waterways that ultimately drain into the Mississippi River and the Gulf of Mexico. This region supports diverse aquatic life and is part of the larger Mississippi River Basin, which is ecologically significant for migratory birds and fish species. Proper wastewater treatment is essential to protect downstream water quality and the sensitive coastal ecosystems of the Gulf.

The plant discharges into local streams and bayous within the Mississippi River Basin, which flows into the Gulf of Mexico. This watershed supports a variety of aquatic species and is an important migratory corridor for birds. The Gulf Coast is ecologically sensitive, with issues such as hypoxia and nutrient pollution, making effective wastewater treatment critical for maintaining water quality.
