CHOCTAW CO 1 GRANT WWT - Secondary Wastewater Treatment in Grant, Oklahoma

CHOCTAW CO 1 GRANT WWT is a municipal wastewater treatment facility located on South Everidge Street in Grant, Choctaw County, Oklahoma. Serving a small population of 263 residents, the plant is part of the rural wastewater infrastructure in southeastern Oklahoma. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 94.64 cubic meters per day and a similar discharge volume, the facility operates at full capacity under typical conditions. As a US plant, it is subject to the Clean Water Act and likely operates under an EPA NPDES permit issued by the Oklahoma Department of Environmental Quality, which sets effluent limits to protect receiving waters. The treated effluent discharges into a local waterway that drains into the Red River basin, eventually reaching the Gulf of Mexico. The plant's operation helps protect downstream aquatic ecosystems and supports the region's water quality goals, particularly in the context of the Red River's role as a major tributary to the Mississippi River system.

The plant discharges into a local stream within the Red River watershed, which flows south through Oklahoma and Texas before emptying into the Mississippi River and ultimately the Gulf of Mexico. The Red River basin supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating potential impacts on downstream water quality and the ecologically sensitive Gulf Coast estuaries.
