Horace WWTP - Greeley County, Kansas Wastewater Treatment Plant

Horace WWTP is a municipal wastewater treatment facility located in Greeley County, Kansas, serving a small population of 156 residents. The plant is situated in a rural area of western Kansas, part of the High Plains region. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal plants. Its designed capacity of 64.35 units and current discharge volume of 56.78 units indicate it operates below capacity. The plant is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Kansas Department of Health and Environment. The treated effluent is discharged into a local watercourse that eventually drains into the Arkansas River basin, contributing to the overall water quality of the region. The plant plays a key role in protecting local groundwater and surface water resources in this agriculturally intensive area.

The plant discharges into a tributary of the Arkansas River, which flows through Kansas and Oklahoma before joining the Mississippi River system. The surrounding watershed supports agricultural activities, and the plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream aquatic habitats and irrigation water quality.
