Whitney WWTP - Secondary Treatment Plant in Dawes County, Nebraska

Whitney WWTP is a municipal wastewater treatment facility located on Old Highway 20 in Dawes County, Nebraska, serving a small population of 89 residents. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal facilities to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 37.85 million gallons per year and currently discharges a similar volume, indicating full utilization. As a small facility in a rural area, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality in the receiving water body. The treated effluent from Whitney WWTP flows into the Niobrara River basin, which drains into the Missouri River and ultimately the Mississippi River system. The Niobrara River supports diverse aquatic life and is an important ecological corridor in the Great Plains region.

The plant discharges into the Niobrara River basin, a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Niobrara River supports a variety of fish and wildlife species, including several state-listed species of concern. The watershed is primarily agricultural, and maintaining water quality is critical for downstream ecosystems and recreational uses.
