Louisville Lagoon Wastewater Treatment Plant, Greens Crossroads, Alabama

Louisville Lagoon is a municipal wastewater treatment facility located on CR 27 in Greens Crossroads, Barbour County, Alabama. The plant serves a small population of 306 residents, reflecting its role as a rural community infrastructure asset in the southeastern United States. The plant provides secondary treatment, the standard level required under the U.S. Clean Water Act for most municipal facilities. With a designed capacity of 378.54 megaliters and an annual discharge volume of 151.42 megaliters, the plant operates well within its capacity, ensuring reliable treatment for the local community. The treated effluent is discharged into nearby streams that drain into the Chattahoochee River watershed, ultimately flowing to the Gulf of Mexico. This small plant plays a vital role in protecting local water quality and the downstream aquatic ecosystem from untreated sewage.

The plant discharges into small tributaries of the Chattahoochee River system, which flows south through Alabama and Georgia to the Apalachicola River and into the Gulf of Mexico. The watershed supports diverse aquatic life, including fish and macroinvertebrates, and is an important resource for regional water supply and recreation. Proper treatment at this facility helps prevent nutrient pollution and pathogen contamination in these sensitive water bodies.
