EL RENO WWT Wastewater Treatment Plant, El Reno, Oklahoma

EL RENO WWT is a municipal wastewater treatment facility located in El Reno, Oklahoma, serving a population of about 17,060. The plant is situated inland in Canadian County, part of the central United States region with a continental climate. As a medium-sized agglomeration, it plays a key role in managing wastewater for the community. Under the U.S. Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through EPA or state-issued NPDES permits. The regulatory framework ensures that effluent quality meets environmental standards for the receiving water body. The plant's design capacity and operational status are part of standard municipal infrastructure. The treated effluent is discharged into a local waterway that ultimately drains into the Canadian River, a tributary of the Arkansas River system. This river network flows through Oklahoma and Arkansas before reaching the Mississippi River and the Gulf of Mexico. The plant's operations help protect downstream aquatic habitats and water quality in the region.

The plant discharges into a local stream that flows into the Canadian River, part of the Arkansas River basin. This watershed supports diverse aquatic life and provides water for agricultural and municipal use downstream. The Canadian River eventually joins the Arkansas River, which flows into the Mississippi River and the Gulf of Mexico, making the plant's effluent management important for regional water quality.
