Barney Lagoon Wastewater Treatment Plant, Barney, North Dakota

Barney Lagoon is a municipal wastewater treatment facility located in Barney, North Dakota, serving a population of approximately 52 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring that wastewater is adequately treated before discharge. As a secondary treatment plant, Barney Lagoon utilizes biological processes to reduce organic matter and suspended solids. The facility has a designed capacity of 37.85 volume units and discharges a similar volume of treated wastewater. Under the U.S. Clean Water Act, such plants operate under National Pollutant Discharge Elimination System (NPDES) permits, which set effluent limits to protect water quality. The treated effluent from Barney Lagoon is discharged into local surface waters, which are part of the Red River of the North basin. This river system flows northward into Canada, eventually reaching Lake Winnipeg. The plant plays a key role in protecting the downstream aquatic environment, including fish habitats and water quality in the Red River Valley.

Barney Lagoon discharges into local streams that feed the Red River of the North, which flows north through North Dakota and Minnesota into Manitoba, Canada, and ultimately into Lake Winnipeg. The Red River basin supports diverse aquatic life and is an important migratory corridor for birds. The plant's secondary treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream waters.
