NEMAHA WWTP - Nemaha County, Nebraska Wastewater Treatment Plant

NEMAHA WWTP is a municipal wastewater treatment facility located in Nemaha County, Nebraska, along Highway 67. The plant serves a small population of 188 residents, reflecting its role in a rural community within the state's southeastern region. The facility provides secondary treatment, a standard level required by the US Clean Water Act for municipal plants. With a designed capacity of 75.71 million gallons per year and a matching discharge volume, the plant operates within its permitted limits. As a small-scale facility, it is subject to state-level NPDES permitting administered by the Nebraska Department of Environment and Energy. The plant's treated effluent is discharged into local waterways that eventually drain into the Missouri River basin. This watershed supports diverse aquatic life and agricultural activities, making proper wastewater treatment essential for maintaining water quality in the region's streams and rivers.

The plant discharges into tributaries of the Missouri River, which flows into the Mississippi River and ultimately the Gulf of Mexico. The local watershed supports agricultural runoff and wildlife habitats, requiring effective nutrient removal to prevent downstream eutrophication. The plant's secondary treatment helps reduce organic pollutants and protect aquatic ecosystems in this rural setting.
