Dierks WWTP - Advanced Wastewater Treatment in Dierks, Arkansas

Dierks WWTP is a municipal wastewater treatment plant located on Mill Complex Road in Dierks, Howard County, Arkansas. The facility serves a population of approximately 1,133 residents, classifying it as a small-scale treatment plant within the state's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 870.64 million gallons per year and an actual discharge volume of 511.03 million gallons per year, the plant operates at about 59% capacity. As a U.S. facility, it is subject to the Clean Water Act and operates under an NPDES permit issued by the Arkansas Department of Energy and Environment. The treated effluent is discharged into local waterways that ultimately drain into the Red River basin, contributing to the Mississippi River watershed. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into local streams that flow into the Red River, which eventually reaches the Mississippi River and the Gulf of Mexico. The Red River basin supports diverse aquatic life and is an important migratory corridor for fish and birds. Advanced treatment at this plant helps reduce nutrient loading, which is critical for preventing hypoxia in the Gulf of Mexico.
