Rutland Lagoon Wastewater Treatment Plant, Rutland, North Dakota

Rutland Lagoon is a wastewater treatment facility located in Rutland, a small town in Sargent County, North Dakota. The plant serves a population of approximately 163 residents, reflecting the rural character of the area. It operates as a lagoon system providing secondary treatment, which is typical for small communities in the region. The plant has a designed capacity of 75.71 cubic meters per day and currently treats an average daily flow of 37.85 cubic meters, indicating it operates well below capacity. As a U.S. facility, it falls under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. Secondary treatment is the minimum standard for municipal wastewater in the United States. The treated effluent from Rutland Lagoon is discharged into local surface waters that eventually drain into the Sheyenne River, a tributary of the Red River of the North. The Red River flows north into Lake Winnipeg in Canada. The plant plays a key role in protecting downstream water quality in this prairie watershed, which supports agricultural activities and diverse aquatic life.

Rutland Lagoon discharges into local streams that flow into the Sheyenne River, part of the Red River of the North basin. The Red River ultimately drains into Lake Winnipeg, a large and ecologically sensitive lake. The watershed is predominantly agricultural, and nutrient loading from wastewater can contribute to eutrophication. The plant's secondary treatment helps reduce organic pollutants and suspended solids, supporting the health of downstream aquatic ecosystems.
