Biscoe WWTP - Prairie County, Arkansas Wastewater Treatment Plant

Biscoe WWTP is a wastewater treatment facility located in Prairie County, Arkansas, serving a small population of 363 residents. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater facilities of this scale. The plant has a designed capacity of 454.25 million gallons per day and currently discharges 3.79 million gallons per day, indicating significant excess capacity. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent from Biscoe WWTP is discharged into local waterways that drain into the Arkansas River basin, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens.

Biscoe WWTP discharges into the Arkansas River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. The region supports diverse aquatic life and is part of the Mississippi Flyway, an important migratory corridor for birds. Nutrient loading from wastewater can contribute to hypoxia in the Gulf, making effective treatment critical.
