The plant serves a population of about 9,557 residents, placing it in the small-to-medium agglomeration category. As a publicly owned treatment works (POTW) in the United States, it is subject to the National Pollutant Discharge Elimination System (NPDES) permitting program under the Clean Water Act. However, for a facility of this scale in Oklahoma, typical secondary treatment or advanced treatment is expected to meet state and federal water quality standards. The plant likely employs conventional activated sludge or lagoon-based treatment, common in the region. Regulatory oversight is provided by the Oklahoma Department of Environmental Quality (ODEQ), which issues NPDES permits that specify effluent limits and monitoring requirements. The treated effluent from Jenks PWA WWT is discharged into a receiving water body within the Arkansas River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting local water quality in the Arkansas River watershed, supporting aquatic life and downstream ecosystems. Its operation helps mitigate nutrient loading and other pollutants that could impact the Gulf of Mexico's hypoxic zone.

Jenks PWA WWT discharges into a tributary of the Arkansas River, which flows through Oklahoma and Arkansas before joining the Mississippi River and emptying into the Gulf of Mexico. The Arkansas River basin supports diverse aquatic habitats and is an important migratory corridor for fish and birds. The plant's discharge must comply with water quality standards to protect downstream ecosystems, including efforts to reduce nutrient pollution that contributes to the Gulf of Mexico's hypoxic zone.
