DAVENPORT WWTP - Secondary Treatment Facility in Davenport, Nebraska

DAVENPORT WWTP is a municipal wastewater treatment plant located in Davenport, Thayer County, Nebraska. It serves a small population of 339 residents, reflecting the rural character of the community. The plant is situated inland, far from coastal influences, and its operations are integral to local water quality management. The plant provides secondary treatment, a standard level required by the U.S. Clean Water Act for municipal facilities. With a designed capacity of 189.27 megaliters per year and a matching discharge volume, the plant operates at full capacity. As a small facility, it is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect receiving waters. The treated effluent is discharged into a local water body that ultimately drains into the Little Blue River basin, a tributary of the Big Blue River, which flows into the Kansas River and then the Missouri River. This watershed supports agricultural land use and provides habitat for diverse aquatic species. The plant's secondary treatment helps reduce organic pollutants and suspended solids, safeguarding downstream water quality.

The plant discharges into a local stream that flows into the Little Blue River, part of the Missouri River watershed. This region is predominantly agricultural, and the receiving waters support fish and wildlife, including species such as channel catfish and freshwater mussels. The plant's secondary treatment reduces biochemical oxygen demand and total suspended solids, helping to maintain the ecological health of the downstream river system.
