Brantley Lagoon Wastewater Treatment Plant, Brantley, Alabama

Brantley Lagoon is a municipal wastewater treatment facility located in Brantley, Crenshaw County, Alabama. Serving a small population of around 800 people, the plant provides secondary treatment to domestic wastewater from the community. As a lagoon-based system, it relies on natural biological processes to treat sewage before discharge. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater. The National Pollutant Discharge Elimination System (NPDES) permits govern discharges from such facilities, ensuring compliance with water quality standards. The plant's designed capacity is 757.08 cubic meters per day, with a current discharge volume of 378.54 cubic meters per day. Treated effluent from Brantley Lagoon is discharged into local streams that eventually drain into the Conecuh River watershed. This river system flows southward through Alabama and into the Gulf of Mexico near the Florida Panhandle. The plant plays a key role in protecting downstream water quality and aquatic habitats in this ecologically diverse region.

Brantley Lagoon discharges into small tributaries of the Conecuh River, which flows through southern Alabama and empties into the Gulf of Mexico. The Conecuh River watershed supports diverse aquatic life, including fish and mussel species, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting downstream ecosystems from eutrophication and oxygen depletion.
