Horseshoe Bend White Oak WWTP - Advanced Treatment in Arkansas

Horseshoe Bend White Oak WWTP is a municipal wastewater treatment plant located at 384 West Tri Lakes Drive in Horseshoe Bend, Arkansas, United States. The facility serves a small population of approximately 500 residents, reflecting its role in a rural community within Izard County. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 757.08 megaliters per year and an actual discharge volume of 113.56 megaliters per year, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the White River basin, a major tributary of the Mississippi River. The advanced treatment level helps protect the ecological health of the receiving waters, supporting aquatic life and downstream water quality.

The plant discharges into the White River watershed, which flows through Arkansas and into the Mississippi River. The White River supports diverse aquatic species and provides habitat for migratory birds. Advanced treatment ensures minimal nutrient and pollutant loading, protecting the river's ecological integrity and downstream uses such as recreation and drinking water.
