BROCK WWTP - Brock, Nebraska Wastewater Treatment Plant

BROCK WWTP is a municipal wastewater treatment plant located on 9th Street in Brock, Nemaha County, Nebraska. The facility serves a small population of approximately 150 residents, reflecting the rural character of the community. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 53.00 million gallons per year and an annual discharge volume of 37.85 million gallons, the plant operates within its capacity. As a small agglomeration, it is subject to state-level NPDES permitting under EPA oversight. The treated effluent is discharged into a local waterway that ultimately drains into the Missouri River watershed. The plant's operations help protect downstream water quality in the Missouri River basin, which supports diverse aquatic life and provides water for communities and agriculture in the region.

The plant discharges into a tributary of the Nemaha River, which flows into the Missouri River near the Nebraska-Iowa border. The Missouri River is a major tributary of the Mississippi River, supporting a diverse ecosystem including fish species such as catfish and sturgeon. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting downstream water quality in this agriculturally intensive region.
