Davis South Jollyville Wastewater Treatment Plant, Davis, Oklahoma

Davis South Jollyville is a wastewater treatment plant located in Davis, Murray County, Oklahoma. It serves a small community of approximately 100 people, reflecting its role as a local facility for a rural area. 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. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 45.42 units, and it currently discharges 45.43 units, indicating near-full utilization. For a plant of this scale, secondary treatment is typical and meets the basic requirements for protecting water quality in inland settings. The treated effluent is discharged into a local water body, likely a stream or river within the Washita River basin, which flows into the Red River and ultimately the Gulf of Mexico. The plant's operations help maintain the ecological health of the surrounding watershed, supporting aquatic life and downstream water quality in this agriculturally influenced region of Oklahoma.

The plant discharges into a local water body that is part of the Washita River watershed, which flows into the Red River and then the Gulf of Mexico. This inland setting supports diverse aquatic habitats and is important for regional biodiversity. The secondary treatment process helps reduce nutrient and pollutant loads, protecting downstream ecosystems from eutrophication and other impacts.
