Winslow STP Wastewater Treatment Plant, Winslow, Nebraska

Winslow STP is a municipal wastewater treatment facility located in Winslow, Nebraska, serving a small population of 162 residents. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for communities of this size. It is situated in Dodge County, an inland area with no coastal influence. The plant has a designed capacity of 37.85 million gallons per day and currently discharges a similar volume, indicating full utilization. As a small 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 remove organic matter and suspended solids. The treated effluent is discharged into local waterways, likely tributaries of the Platte River or Missouri River system, which ultimately drain into the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting the local watershed from nutrient pollution and maintaining water quality for downstream ecosystems.

The plant discharges into the Platte River basin, which flows into the Missouri River and then the Mississippi River, eventually reaching the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
