POCOLA MA WWT - Secondary Wastewater Treatment Plant in Pocola, Oklahoma

POCOLA MA WWT is a municipal wastewater treatment facility located in Pocola, LeFlore County, Oklahoma. Serving a population of approximately 1,225, the plant provides essential sanitation services for this small community in the eastern part of the state. The plant operates with secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 454.25 volume units, the facility manages the community's wastewater flow effectively. As a U.S. plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets discharge limits to protect water quality. The treated effluent is discharged into local receiving waters that ultimately drain into the Arkansas River basin. This watershed supports diverse aquatic life and provides water for downstream communities. The plant's location inland, away from coastal areas, reduces direct marine impact but still requires careful management to protect freshwater ecosystems.

The plant discharges into local streams that are part of the Arkansas River watershed, which flows through Oklahoma and Arkansas before joining the Mississippi River. This inland basin supports diverse aquatic habitats and is important for regional water supply. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting downstream water quality and aquatic life.
