Dyess WWTP - Secondary Wastewater Treatment in Dyess, Arkansas

Dyess WWTP is a municipal wastewater treatment facility located on 3rd Street in Dyess, Mississippi County, Arkansas. The plant serves a small population of 410 residents, reflecting the rural character of the community in the Mississippi River Delta region. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities. With a designed capacity of 227.12 million gallons per year and an actual discharge volume of 30.28 million gallons per year, the plant operates well below its capacity, indicating ample headroom for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River, a major ecological and economic artery. The plant's operations help protect downstream water quality in the Mississippi River basin, supporting aquatic life and recreational uses.

The plant discharges into the Mississippi River watershed, which flows into the Gulf of Mexico. This region is part of the Mississippi River Delta, an ecologically sensitive area that supports diverse aquatic life and is a critical migratory corridor for birds. Proper wastewater treatment is essential to reduce nutrient loading that contributes to the Gulf of Mexico hypoxic zone.
