ADA WWT Wastewater Treatment Plant, Ada, Oklahoma

ADA WWT is a municipal wastewater treatment facility located in Ada, Pontotoc County, Oklahoma, serving a population of about 15,700. As a medium-sized agglomeration, the plant is part of the region's water infrastructure, handling residential and commercial wastewater from the city. Under the U.S. Clean Water Act, wastewater treatment plants of this scale are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant's operations are regulated by the Oklahoma Department of Environmental Quality, ensuring compliance with federal and state water quality standards. The treated effluent from ADA WWT is discharged into local streams that flow into the Washita River, a tributary of the Red River. The Red River ultimately drains into the Gulf of Mexico, making the plant's performance important for downstream water quality and aquatic ecosystems in the Mississippi River basin.

ADA WWT discharges into the Washita River watershed, which flows into the Red River and eventually the Gulf of Mexico. The receiving waters support diverse aquatic life and are used for recreation and agriculture. The plant's treatment processes help protect downstream ecosystems from nutrient pollution and pathogens, contributing to the ecological health of the Red River basin.
