Kellogg WWTP - Secondary Wastewater Treatment in Jasper County, Iowa

Kellogg WWTP is a municipal wastewater treatment facility located in Kellogg Township, Jasper County, Iowa, United States. The plant serves a small population of 606 residents and is part of the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. It has a designed capacity of 378.54 cubic meters per day and discharges a similar volume, indicating full utilization. As a small facility in inland Iowa, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Iowa Department of Natural Resources. The treated effluent is discharged to a local water body, likely a stream or river within the Mississippi River basin. The plant's location away from the coast reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed, which eventually drains to the Gulf of Mexico via the Mississippi River. Protecting local water quality is important for aquatic life and downstream communities.

The plant discharges into a local water body within the Mississippi River basin, which flows south to the Gulf of Mexico. The watershed supports diverse aquatic ecosystems, including fish and macroinvertebrate communities. As a small inland facility, its nutrient and pollutant loads are relatively low, but cumulative effects from multiple sources in the basin can contribute to hypoxia in the Gulf. Proper secondary treatment helps reduce organic matter and suspended solids, protecting local stream health.
