WALCOTT STP NORTH Wastewater Treatment Plant, Walcott, Iowa

WALCOTT STP NORTH is a municipal wastewater treatment plant located in Walcott, Iowa, serving a small population of 185 residents. The facility is situated in Scott County, part of the Blue Grass Township, and plays a key role in managing local wastewater for this rural community. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 75.71 units and a similar discharge volume, it operates under the US Clean Water Act, which requires NPDES permits for all point-source discharges. For small plants like this, secondary treatment is the typical regulatory requirement. The treated effluent is discharged into a local water body, ultimately contributing to the Mississippi River basin via regional tributaries. This watershed supports diverse aquatic life and is an important ecological corridor in the Midwest. The plant's operations help protect downstream water quality in the broader Mississippi River system.

The plant discharges into a local stream that flows into the Mississippi River basin, a major watershed draining much of the central United States. This region supports diverse aquatic species and is a critical migratory route for birds and fish. The secondary treatment process reduces pollutants to protect downstream ecosystems, including wetlands and floodplains along the Mississippi River.
