EPPS LAGOON Wastewater Treatment Plant, Epps, Louisiana

EPPS LAGOON is a wastewater treatment facility located in Epps, West Carroll Parish, Louisiana, United States. The plant serves a small population of 655 residents, reflecting its role in a rural community. It operates with advanced treatment processes, ensuring high-quality effluent before discharge. The plant has a designed capacity of 340.69 thousand cubic meters per year, with a discharge volume matching that figure, indicating full utilization. As an advanced treatment facility, it goes beyond secondary treatment standards, likely incorporating nutrient removal or other tertiary processes. Under the US Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. The treated effluent is discharged into local waterways that drain into the Mississippi River basin, eventually reaching the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region's agricultural landscape.

EPPS LAGOON discharges into the Bayou Macon watershed, which flows southward to the Mississippi River and ultimately the Gulf of Mexico. The surrounding area is part of the Mississippi Alluvial Plain, characterized by fertile soils and extensive agriculture. The plant's advanced treatment reduces nutrient loads, helping to mitigate hypoxia in the Gulf of Mexico.
