Brownville WWTP is a municipal wastewater treatment facility located at 100 South 1st Street in Brownville, Nebraska, a small community in Nemaha County. The plant serves a population of 132, classifying it as a very small agglomeration under US regulatory frameworks. The plant provides secondary treatment, which is the minimum standard required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 75.71 units, the plant operates at full capacity based on reported discharge volume. As a small facility, it is subject to state-level NPDES permitting administered by the Nebraska Department of Environment and Energy. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed, contributing to the Mississippi River basin. The plant plays a critical role in protecting local water quality and downstream ecosystems in the Missouri River corridor.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The Missouri River supports diverse aquatic life, including several native fish species and migratory birds. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream water quality in this agriculturally intensive region.
