WOLBACH WWTP - Wolbach, Nebraska Wastewater Treatment Plant

WOLBACH WWTP is a municipal wastewater treatment facility located on Bluff Street in Wolbach, Nebraska, serving a small population of 301 residents. The plant provides secondary treatment, which is the standard biological treatment process required under the US Clean Water Act for most municipal facilities. The plant has a designed capacity of 151.42 megaliters per year and currently discharges approximately 113.56 megaliters annually, indicating operational headroom. As a US facility, it operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit, typically issued by the Nebraska Department of Environment and Energy, which sets effluent limits to protect water quality. The treated effluent is discharged to a local waterway within the Platte River basin, which ultimately drains to the Missouri River and then the Mississippi River. The plant plays a key role in protecting downstream aquatic ecosystems by reducing organic pollutants and nutrients before discharge.

The plant discharges into a tributary of the Platte River basin, which flows eastward to the Missouri River and eventually the Mississippi River. This watershed supports diverse aquatic life and provides critical habitat for migratory birds along the Central Flyway. The secondary treatment process helps reduce biochemical oxygen demand and suspended solids, protecting downstream water quality in this agriculturally intensive region.
