DAWSON WWTP - Dawson, Nebraska Wastewater Treatment Plant

DAWSON WWTP is a municipal wastewater treatment facility located in Dawson, Nebraska, a small community in Richardson County. The plant serves a population of 255 and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. Its designed capacity is 75.71 cubic meters per day, matching the current discharge volume, indicating the plant operates at full capacity. As a small facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Nebraska Department of Environment and Energy. The treated effluent is discharged into a local water body that ultimately drains into the Missouri River watershed. The Missouri River flows into the Mississippi River and then to the Gulf of Mexico. The plant's discharge contributes to the overall water quality in this important river basin, which supports diverse aquatic life and agricultural uses.

The plant discharges into a local stream that is part of the Missouri River basin. The Missouri River flows southward to join the Mississippi River, which empties into the Gulf of Mexico. This watershed supports a variety of fish and wildlife, including migratory birds and freshwater mussels. The plant's secondary treatment helps protect downstream water quality in this ecologically significant river system.
