Osceola WWTP - Secondary Treatment Facility in Polk County, Nebraska

Osceola WWTP is a municipal wastewater treatment facility located on County Road 130 in Polk County, Nebraska. It serves a small population of 921 residents, reflecting the rural character of the area. The plant 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 standard biological process that removes organic matter and suspended solids. Its designed capacity is 378.54 cubic meters per day, matching the current discharge volume. As a small facility in the U.S. Midwest, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Nebraska Department of Environment and Energy. The treated effluent is discharged into local waterways that drain into the Platte River basin, a major tributary of the Missouri River. The Platte River system supports diverse aquatic life and is an important migratory corridor for birds. The plant's discharge contributes to the overall water quality in this agriculturally intensive region.

The plant's discharge enters local streams that flow into the Platte River, which eventually joins the Missouri River and then the Mississippi River, draining into the Gulf of Mexico. The Platte River basin is ecologically significant as a stopover for sandhill cranes and other migratory birds. The surrounding area is predominantly agricultural, so the plant helps protect downstream water quality from nutrient loading.
