Owens Crossroads WWTP - Advanced Wastewater Treatment in Owens Cross Roads, Alabama

Owens Crossroads WWTP is a municipal wastewater treatment facility located in Owens Cross Roads, Madison County, Alabama, United States. The plant serves a population of 1,124 and operates with advanced treatment processes to ensure high-quality effluent. As an advanced treatment plant, it goes beyond secondary treatment standards, likely incorporating nutrient removal or other tertiary processes. The facility has a designed capacity of 1,514.16 m³/day and currently treats 757.08 m³/day, indicating it operates at about 50% capacity. Under the US Clean Water Act, such plants are regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Alabama Department of Environmental Management. The treated effluent is discharged into local waterways that ultimately drain into the Tennessee River basin. The Tennessee River flows westward through Alabama before joining the Ohio River, which feeds into the Mississippi River and eventually the Gulf of Mexico. The plant's advanced treatment helps protect downstream aquatic ecosystems and water quality in this important regional watershed.

The plant discharges into the Tennessee River basin, a major tributary of the Ohio-Mississippi river system that drains into the Gulf of Mexico. The Tennessee River supports diverse aquatic life, including several species of freshwater mussels and fish. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing eutrophication in downstream reservoirs and the Gulf of Mexico's hypoxic zone.
