Holbrook WWTP - Secondary Wastewater Treatment in Holbrook, Nebraska

Holbrook WWTP is a municipal wastewater treatment facility located in Holbrook, Nebraska, serving a small population of 305 residents. The plant provides secondary treatment, a standard level for communities of this size in the United States, ensuring compliance with federal Clean Water Act requirements. The plant's designed capacity matches its discharge volume of 151.42 units, indicating consistent operation within its engineered limits. As a US facility, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local waterway, likely a tributary of the Republican River basin, which flows through Nebraska and Kansas. This discharge supports downstream aquatic ecosystems and agricultural water supplies. The plant's inland location reduces direct marine impact, but careful management is essential to maintain the health of the regional watershed.

The plant discharges into a receiving water body within the Republican River basin, which ultimately drains into the Kansas River and then the Missouri River. This inland watershed supports diverse aquatic life and provides water for irrigation and recreation. The secondary treatment process helps protect downstream ecosystems from nutrient pollution and organic loading.
