OPP EASTSIDE WWTP - Advanced Wastewater Treatment in Opp, Alabama

OPP EASTSIDE WWTP is a municipal wastewater treatment facility located in Opp, Covington County, Alabama. The plant serves a population of approximately 1,020 residents, reflecting a small community scale typical of rural southeastern U.S. towns. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,514.16 thousand gallons per day and an average discharge volume of 753.30 thousand gallons per day, the facility operates well within its capacity. Under the U.S. Clean Water Act, such plants must comply with National Pollutant Discharge Elimination System (NPDES) permits issued by the Alabama Department of Environmental Management, ensuring effluent quality protects receiving waters. The treated effluent is discharged into local waterways that ultimately drain into the Conecuh River basin, which flows south to the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region's rivers and estuaries.

The plant discharges into the Conecuh River watershed, which flows through southern Alabama into the Gulf of Mexico. This region supports diverse aquatic life, including fish and invertebrates, and the river provides habitat for migratory species. Advanced treatment reduces nutrient loading, helping to prevent eutrophication in downstream estuaries and coastal waters.
