Dozier Lagoon Wastewater Treatment Plant - Dozier, Alabama

Dozier Lagoon is a municipal wastewater treatment facility located in Dozier, Crenshaw County, Alabama. Serving a small population of 391 residents, the plant provides secondary treatment to meet state and federal water quality standards. The facility operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal plants discharging to surface waters. The plant employs secondary treatment processes, which typically involve biological treatment to remove organic matter and suspended solids. With a designed capacity of 227.12 units and an average daily discharge of 128.70 units, the plant operates below its full capacity, indicating room for future growth. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect receiving waters. The treated effluent from Dozier Lagoon is discharged into local waterways that ultimately drain into the Gulf of Mexico via the Conecuh River and Escambia Bay. The plant plays a key role in protecting downstream aquatic ecosystems, including freshwater habitats and estuarine environments that support diverse fish and wildlife species.

Dozier Lagoon discharges into the Conecuh River watershed, which flows southward through Alabama and Florida before emptying into Escambia Bay and the Gulf of Mexico. The receiving waters support a variety of aquatic life, including freshwater fish and migratory species. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating the risk of eutrophication in downstream estuaries and maintaining water quality for recreational and ecological uses.
