Blount County West Lagoon Wastewater Treatment Plant, Warrior, Alabama

Blount County West Lagoon is a municipal wastewater treatment facility located in Warrior, Blount County, Alabama. The plant serves a population of approximately 2,530 residents, classifying it as a small-scale treatment facility within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for most municipal facilities. With a designed capacity of 567.81 million gallons per year and an actual discharge volume of 208.20 million gallons per year, the plant operates well below its capacity, indicating room for future growth. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Alabama Department of Environmental Management, which sets effluent limits to protect water quality. The treated effluent from the plant is discharged into local streams that are part of the Black Warrior River watershed. The Black Warrior River flows into the Mobile River and eventually reaches the Mobile Bay estuary, a critical ecological zone in the northern Gulf of Mexico. The plant's operations help protect downstream aquatic habitats and support the overall health of the Mobile Bay ecosystem.

The plant discharges into tributaries of the Black Warrior River, which flows into the Mobile River and ultimately the Mobile Bay estuary. This estuary supports diverse aquatic life, including fish, shellfish, and migratory birds. The watershed is ecologically sensitive due to its role in nutrient cycling and as a nursery for marine species. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in this important coastal ecosystem.
