RATTAN WWT - Rattan, Oklahoma Wastewater Treatment Plant

RATTAN WWT is a municipal wastewater treatment facility located in Rattan, Pushmataha County, Oklahoma. The plant serves a small community of approximately 320 residents, providing essential sanitation services for this rural area in the southeastern part of the state. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 113.56 megaliters per year, the facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Oklahoma Department of Environmental Quality. This regulatory framework ensures that treated effluent meets water quality standards before discharge. The treated wastewater is discharged into local waterways that ultimately drain into the Kiamichi River basin, a tributary of the Red River. The Red River flows southward to the Mississippi River and eventually into the Gulf of Mexico. The plant's operations help protect the water quality of these downstream ecosystems, which support diverse aquatic life and provide habitat for fish and wildlife.

The plant discharges into the Kiamichi River watershed, which flows into the Red River and then the Mississippi River before reaching the Gulf of Mexico. This region features forested hills and agricultural lands, and the waterways support diverse aquatic species including several native fish and mussel populations. Proper wastewater treatment is critical to maintaining water quality in this ecologically sensitive area.
