ONEONTA WWTP - Blount County, Alabama Wastewater Treatment Plant

ONEONTA WWTP is a municipal wastewater treatment facility located in Blount County, Alabama, serving a population of approximately 4,600 residents. The plant is situated in a rural area of north-central Alabama, within the Black Warrior River watershed. As a US facility, the plant operates under the Clean Water Act, administered by the Alabama Department of Environmental Management (ADEM). For a plant serving a population of this size, secondary treatment is typically required to meet National Pollutant Discharge Elimination System (NPDES) permit limits. The regulatory framework ensures compliance with water quality standards. The treated effluent from ONEONTA WWTP discharges into a local stream that flows into the Black Warrior River, which ultimately drains to the Mobile River and the Gulf of Mexico. The plant plays a key role in protecting downstream water quality in this ecologically important river system, which supports diverse aquatic life and provides drinking water for communities in the region.

The plant discharges into a tributary of the Black Warrior River, a major waterway in Alabama that flows into the Mobile River and then the Gulf of Mexico. The Black Warrior River supports diverse aquatic species, including several endemic fish and mussel species, and provides habitat for migratory birds. The watershed is also important for regional water supply and recreation.
