DEPEW WWT - Depew, Oklahoma Wastewater Treatment Plant

DEPEW WWT is a municipal wastewater treatment plant located in Depew, Creek County, Oklahoma, along US Historic 66. The facility serves a small community of 564 residents, reflecting the rural character of the area. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the regulatory framework of the US Clean Water Act, administered by the Oklahoma Department of Environmental Quality. For small communities like Depew, secondary treatment is the standard requirement, ensuring compliance with National Pollutant Discharge Elimination System (NPDES) permits. The plant's designed capacity of 257.41 m³/day and current discharge volume of 189.27 m³/day indicate it operates below capacity, allowing for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Arkansas River basin, part of the Mississippi River watershed. This inland location, over 50 km from the coast, reduces direct marine impact. The plant plays a key role in protecting local streams and groundwater from untreated sewage, supporting the ecological health of the region.

The plant discharges into a tributary of the Arkansas River, which flows into the Mississippi River and eventually the Gulf of Mexico. This inland watershed supports diverse aquatic life and is important for regional water quality. The secondary treatment process reduces nutrient loads, helping to prevent eutrophication in downstream water bodies.
