CADDO CO 1 LOOKEBA Wastewater Treatment Plant, Lookeba, Oklahoma

CADDO CO 1 LOOKEBA is a municipal wastewater treatment facility located on Oak Street in Lookeba, Caddo County, Oklahoma. The plant serves a small population of 131 residents, reflecting the rural character of the area. It operates under the regulatory framework of the United States Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. Its designed capacity is 79.49 volume units, matching the reported discharge volume. For a facility of this small scale, secondary treatment meets typical state and federal requirements for protecting water quality in receiving streams. The treated effluent is discharged into local creeks that drain into the Washita River basin, eventually reaching the Red River and the Gulf of Mexico. The plant plays a key role in safeguarding the region's surface water quality, supporting aquatic life and downstream uses such as recreation and agriculture.

The plant discharges into small tributaries of the Washita River, which flows through central Oklahoma and joins the Red River on the Texas-Oklahoma border. The Red River ultimately empties into the Gulf of Mexico. The watershed supports diverse aquatic species and is an important resource for irrigation and livestock watering. Maintaining secondary treatment standards helps prevent nutrient enrichment and oxygen depletion in these sensitive prairie streams.
