Ratliff City WWT - Secondary Wastewater Treatment in Carter County, Oklahoma

Ratliff City WWT is a municipal wastewater treatment facility located on Delta Road in Carter County, Oklahoma, within the United States. The plant serves a small population of 130 residents, reflecting its role in a rural community. The facility provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 37.85 units, the plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges. For small plants like this, permits typically include effluent limits for biochemical oxygen demand, total suspended solids, and pH. The treated effluent is discharged into a local waterbody, ultimately contributing to the Red River basin. This watershed supports diverse aquatic life and is an important resource for agriculture and recreation in southern Oklahoma. Proper treatment helps protect downstream water quality and ecosystem health.

The plant discharges into a tributary of the Red River, which flows south into Texas and eventually empties into the Mississippi River and the Gulf of Mexico. This watershed supports a variety of fish and wildlife species, including several that are ecologically sensitive. Maintaining secondary treatment standards helps prevent nutrient pollution and protects the aquatic habitat in this region.
