HAIGLER WWTP - Dundy County, Nebraska Wastewater Treatment Plant

HAIGLER WWTP is a municipal wastewater treatment facility located on Highway 34 in Dundy County, Nebraska, serving a small population of 225 residents. The plant provides secondary treatment, which is the standard level required for most US municipal plants under the Clean Water Act. The plant's designed capacity is 105.99 volume units, matching its discharge volume, indicating it operates at full capacity. As a small facility in rural Nebraska, it is subject to EPA NPDES permitting through the state's delegated authority, ensuring compliance with effluent limits. The treated effluent is discharged into a local waterway that ultimately drains into the Republican River basin, which flows through Nebraska and Kansas. The plant's operations help protect local groundwater and surface water quality in this agricultural region.

The plant discharges into a tributary of the Republican River, which flows through the Great Plains and joins the Kansas River before reaching the Missouri River and ultimately the Mississippi River system. This watershed supports irrigated agriculture and provides habitat for fish and migratory birds. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream water quality in this semi-arid region.
