GOWRIE WWTP - Wastewater Treatment Plant in Gowrie, Iowa

GOWRIE WWTP is a municipal wastewater treatment facility located in Gowrie, Iowa, a small community in Webster County. The plant serves a population of about 1,038 people, typical of a small agglomeration in the rural Midwest. It is situated inland, far from coastal areas, and discharges into local waterways that eventually drain to the Mississippi River basin. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. It is sized to handle the local population's wastewater flow. The treated effluent from GOWRIE WWTP enters local streams that flow into the Des Moines River, a major tributary of the Mississippi River. This watershed supports diverse aquatic life and provides water for downstream communities and agriculture. The plant's operation helps maintain the ecological health of these waterways by reducing nutrient and pathogen loads.

GOWRIE WWTP discharges into local tributaries of the Des Moines River, which flows southeast to join the Mississippi River. This watershed is part of the larger Mississippi River basin, which drains into the Gulf of Mexico. The receiving waters support a variety of fish and wildlife, and the plant's treatment helps mitigate nutrient pollution that can contribute to hypoxia in the Gulf. The area is primarily agricultural, so the plant plays a role in managing local water quality.
