Oshkosh WWTP - Secondary Wastewater Treatment in Oshkosh, Nebraska

Oshkosh WWTP is a municipal wastewater treatment facility located in Oshkosh, Garden County, Nebraska. The plant serves a small population of 1,128 residents and provides secondary treatment, which is the standard level required by the US Clean Water Act for most municipal plants. The facility has a designed capacity of 416.39 m³/day and currently treats an average daily flow of 378.54 m³/day. The plant operates under the US National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Nebraska Department of Environment and Energy. Secondary treatment ensures removal of biodegradable organic matter and suspended solids, meeting typical effluent limits for BOD and TSS. As a small agglomeration, the plant's treatment level aligns with federal requirements for protecting water quality. The treated effluent is discharged to a local waterway that eventually drains into the North Platte River, part of the Platte River basin. This watershed supports agricultural irrigation and provides habitat for migratory birds along the Central Flyway. The plant's location in the High Plains region means water resources are critical for both ecological and economic uses.

The plant discharges into a tributary of the North Platte River, which flows into the Platte River and ultimately the Missouri River. This watershed is part of the Mississippi River basin, draining to the Gulf of Mexico. The region's semi-arid climate makes water quality management essential for sustaining local agriculture and the Platte River ecosystem, which supports diverse aquatic life and serves as a critical stopover for migratory waterfowl.
