Neligh WWTP - Municipal Wastewater Treatment in Neligh, Nebraska

Neligh WWTP is a municipal wastewater treatment facility located in Neligh, Antelope County, Nebraska, serving a population of about 1,742 residents. The plant is situated along Highway 275 and operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required for most municipal facilities in the U.S. to reduce organic matter and suspended solids. With a designed capacity of 738.15 units and a current discharge volume of 541.31 units, the plant operates below its capacity, indicating room for future growth or seasonal fluctuations. The treated effluent is discharged into a local water body, likely a tributary of the Elkhorn River, which flows into the Platte River and eventually the Missouri River. This watershed supports diverse aquatic life and agricultural activities, making proper treatment essential for maintaining water quality in the region.

The plant's discharge enters a local watercourse that drains into the Elkhorn River, a tributary of the Platte River system. The Platte River is a critical migratory corridor for sandhill cranes and other waterfowl, and its basin supports extensive irrigation and livestock operations. Proper wastewater treatment helps protect these downstream ecosystems from nutrient pollution and pathogens.
