Venturia Lagoon Wastewater Treatment Plant, McIntosh County, North Dakota

Venturia Lagoon is a wastewater treatment facility located in rural McIntosh County, North Dakota, United States. The plant serves a very small population of 10 people, reflecting its role in a sparsely populated agricultural area. As a lagoon-based system, it provides secondary treatment to manage domestic wastewater from the local community. Operating under the U.S. Clean Water Act, the plant is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The plant's design capacity is 3.79 million gallons per day, with a discharge volume matching that figure, indicating full utilization. The treatment process is typical for small rural facilities, relying on natural biological processes in lagoons to reduce pollutants. The treated effluent is discharged into nearby surface waters, ultimately contributing to the Missouri River watershed. This region is part of the Northern Great Plains, where water resources are critical for agriculture and wildlife. The plant's operations help protect local streams and groundwater from untreated sewage, supporting the ecological health of the prairie landscape.

The plant discharges into local streams that drain into the Missouri River basin, a major waterway flowing through the Great Plains to the Mississippi River and the Gulf of Mexico. The surrounding area is characterized by agricultural land and prairie ecosystems, where maintaining water quality is essential for livestock, irrigation, and native species. The plant's secondary treatment helps reduce nutrient loading and pathogen risks in this sensitive watershed.
