Haworth WWT - Secondary Wastewater Treatment Plant in Haworth, Oklahoma

Haworth WWT is a municipal wastewater treatment facility located in Haworth, McCurtain County, Oklahoma. It serves a small population of 354 residents, reflecting the rural character of the area. The plant is situated in the southeastern part of the state, near the border with Arkansas. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Under the National Pollutant Discharge Elimination System (NPDES), facilities of this scale must meet effluent limits to protect water quality. The plant's designed capacity is 151.42 thousand cubic meters per year, matching its discharge volume, indicating full utilization. The treated effluent is discharged into a local water body that ultimately drains into the Red River basin. The Red River flows southward to the Mississippi River and then to the Gulf of Mexico. The plant's operations help protect downstream aquatic ecosystems and maintain water quality in the region.

Haworth WWT discharges into a tributary of the Red River, which flows through Oklahoma and Arkansas before joining the Mississippi River. The Red River basin supports diverse aquatic life and is an important migratory corridor for fish and birds. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of the downstream waters.
