VAN WERT WWTP - Decatur County, Iowa Wastewater Treatment Plant

VAN WERT WWTP is a municipal wastewater treatment facility located in Decatur County, Iowa, United States. The plant serves a small population of 249 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity matches the current discharge volume of 75.71 units, indicating the facility is operating at full capacity. As a small-scale plant, it is subject to state-level oversight by the Iowa Department of Natural Resources, which ensures compliance with water quality standards. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River Basin. This watershed supports diverse aquatic life and provides water for agricultural and recreational uses downstream. The plant's operations help protect local streams from nutrient pollution and pathogens, contributing to the ecological health of the region.

The plant discharges into a tributary of the Mississippi River Basin, which flows into the Gulf of Mexico. This watershed is ecologically significant, supporting diverse fish and wildlife habitats. The discharge contributes to nutrient loads that can affect downstream water quality, including the hypoxic zone in the Gulf. Proper treatment helps mitigate these impacts.
