DILL CITY WWT is a municipal wastewater treatment facility located in Washita County, Oklahoma, serving a small population of 526 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. As a secondary treatment plant, it meets the minimum federal standards for organic matter and suspended solids removal, ensuring compliance with water quality goals for small communities. The plant has a designed capacity of 189.27 megaliters per year and currently discharges a similar volume, indicating full utilization of its treatment capacity. Secondary treatment typically involves biological processes such as activated sludge or trickling filters to reduce biochemical oxygen demand and total suspended solids. It is assumed to be active based on discharge data. The treated effluent is discharged into a local water body within the Washita River basin, which ultimately drains into the Red River and then the Gulf of Mexico. This inland location, over 50 km from the coast, reduces direct marine impact. The plant plays a key role in protecting local water quality and downstream ecosystems in the Red River watershed.
Environmental context
The plant discharges into a tributary of the Washita River, which flows into the Red River and eventually the Gulf of Mexico. This inland watershed supports diverse aquatic life and is important for regional agriculture and recreation. The secondary treatment level helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
