Oologah PWA WWT - Advanced Wastewater Treatment in Rogers County, Oklahoma

Oologah PWA WWT is a wastewater treatment facility located in Rogers County, Oklahoma, United States. It serves a small community of 883 residents, providing advanced treatment to protect local water quality. The plant is situated inland, away from coastal areas, and operates as part of the municipal wastewater infrastructure for the region. The plant utilizes advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 1135.62 m³/day and an actual discharge volume of 378.54 m³/day, the facility operates well below its capacity, indicating room for future growth. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality. The treated effluent from Oologah PWA WWT is discharged into local waterways that ultimately drain into the Verdigris River basin, part of the larger Arkansas River watershed. This region supports diverse aquatic life and is important for recreational activities. The advanced treatment helps minimize nutrient loading and protects downstream ecosystems.

The plant discharges into local streams that flow into the Verdigris River, a tributary of the Arkansas River, which eventually reaches the Mississippi River and the Gulf of Mexico. The watershed supports a variety of fish and wildlife, and the advanced treatment reduces the risk of eutrophication in downstream water bodies. The area is characterized by rolling hills and agricultural land, making nutrient control important for maintaining water quality.
