UTE WWTL - Secondary Wastewater Treatment Plant in Monona County, Iowa

UTE WWTL is a municipal wastewater treatment facility located in Monona County, Iowa, serving a small rural population of 385 residents. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for all publicly owned treatment works to protect water quality. The plant has a designed capacity of 227.12 cubic meters per day and currently treats an average daily flow of 189.27 cubic meters, indicating it operates below its design capacity. As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids, meeting the national effluent standards for conventional pollutants. The treated effluent is discharged to local streams that drain into the Missouri River watershed. This region supports agricultural activities and provides habitat for diverse aquatic species. The plant's operation helps maintain the ecological health of downstream water bodies by reducing nutrient and pollutant loads.

UTE WWTL discharges into small tributaries that flow into the Missouri River, a major waterway that eventually joins the Mississippi River. The local watershed is predominantly agricultural, and the plant's secondary treatment helps control nutrient runoff and protect downstream aquatic ecosystems. The Missouri River supports a variety of fish species and provides drinking water for communities along its course.
