DAVIDSON WWT Wastewater Treatment Plant, Tillman County, Oklahoma

DAVIDSON WWT is a municipal wastewater treatment facility located in Tillman County, Oklahoma, serving a small population of 375 residents. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for all publicly owned treatment works. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 151.42 million liters per day and a discharge volume of 151.42 million liters per day, the facility operates at full capacity. As a small inland plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Oklahoma Department of Environmental Quality. The treated effluent is discharged to local streams that drain into the Red River basin, ultimately reaching the Gulf of Mexico. The plant plays a critical role in protecting local water quality and downstream ecosystems in the southern Great Plains region.

The plant discharges into tributaries of the Red River, which flows into the Mississippi River and then the Gulf of Mexico. The surrounding watershed supports agricultural activities and provides habitat for aquatic species. Protecting water quality in this region is important for maintaining the ecological health of the Red River basin and the Gulf's coastal zone.
