WETUMKA WWT SOUTH - Wetumka, Oklahoma Wastewater Treatment Plant

WETUMKA WWT SOUTH is a municipal wastewater treatment plant located in Wetumka, Hughes County, Oklahoma. Serving a population of approximately 972, the plant provides secondary treatment to meet Clean Water Act standards for small communities in the region. The plant has a designed capacity of 386.11 thousand gallons per day and currently treats an average daily flow of 340.69 thousand gallons. As a secondary treatment facility, it utilizes biological processes to reduce organic pollutants and suspended solids before discharge. Under the US EPA National Pollutant Discharge Elimination System (NPDES), plants of this scale are required to meet effluent limits for BOD, TSS, and other parameters. The treated effluent is discharged into local streams that drain into the Canadian River watershed, ultimately flowing into the Arkansas River and Mississippi River system. This contributes to the water quality of downstream ecosystems, including the Mississippi River Delta, which supports diverse aquatic life and important migratory bird habitats.

The plant discharges into tributaries of the Canadian River, which flows into the Arkansas River and then the Mississippi River. This watershed supports diverse aquatic species and provides critical habitat for migratory waterfowl along the Central Flyway. The secondary treatment process helps protect downstream water quality by reducing nutrient and organic loads before discharge.
