Elmore City WWT - Secondary Wastewater Treatment Plant in Elmore City, Oklahoma

Elmore City WWT is a municipal wastewater treatment facility located in Elmore City, Garvin County, Oklahoma. The plant serves a population of approximately 760 residents, making it a small-scale facility within the state's wastewater infrastructure. It is situated inland, far from coastal areas, and its operations are governed by the US Clean Water Act and state-level regulations. The plant provides secondary treatment, which is the standard level required for municipal wastewater in the United States. Its designed capacity is 340.69 thousand cubic meters per year, with an actual discharge volume of 302.83 thousand cubic meters annually. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. 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 plays a key role in protecting local water resources and downstream ecosystems from untreated sewage.

The plant discharges into a tributary of the Washita River, which flows into the Red River and then the Gulf of Mexico. The receiving waters support diverse aquatic life and are part of a larger watershed that provides habitat for fish and migratory birds. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream water quality in this agriculturally influenced region.
