Stevenson WWTP - Secondary Wastewater Treatment in Stevenson, Alabama

Stevenson WWTP is a municipal wastewater treatment facility located in Stevenson, Jackson County, Alabama, United States. The plant serves a small population of around 1,976 people, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges to surface waters. The plant provides secondary treatment, a standard biological process that removes biodegradable organic matter and suspended solids. With a designed capacity of 2,839.05 cubic meters per day, the plant currently treats an average daily flow of 946.35 cubic meters, indicating ample reserve capacity for future growth. The facility is owned and operated by the local municipality, ensuring compliance with state and federal discharge permits. The treated effluent is discharged into a local waterway that ultimately drains into the Tennessee River basin. The Tennessee River flows westward through Alabama before joining the Ohio River, which feeds into the Mississippi River system. This downstream connection highlights the plant's role in protecting water quality in a major US watershed, supporting aquatic life and downstream communities.

The plant discharges into a tributary of the Tennessee River, which flows through northeastern Alabama and eventually joins the Ohio River. The Tennessee River basin supports diverse aquatic ecosystems, including fish species such as bass and catfish, and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this ecologically significant river system.
