Haileyville WWT - Advanced Wastewater Treatment in Haileyville, Oklahoma

Haileyville WWT is a municipal wastewater treatment facility located in Haileyville, Oklahoma, a small town in Pittsburg County. The plant serves a population of approximately 920 residents, reflecting its role in managing domestic wastewater for a small community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 492.10 volume units and an average daily discharge of 336.90 volume units, the facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Oklahoma Department of Environmental Quality. Plants of this scale typically require National Pollutant Discharge Elimination System (NPDES) permits to ensure compliance with water quality standards. The treated effluent is discharged into a local water body, which ultimately drains into the Arkansas River basin and then the Mississippi River system. This downstream connection highlights the plant's role in protecting water quality in a region that supports diverse aquatic life and contributes to the larger Gulf of Mexico ecosystem.

The plant's discharge enters a local stream that flows into the Arkansas River basin, part of the larger Mississippi River watershed. This region supports diverse aquatic species and provides habitat for migratory birds. The advanced treatment level helps reduce nutrient loading, which is critical for preventing downstream eutrophication in the Gulf of Mexico.
