COLUMBUS LAGOON Wastewater Treatment Plant, Columbus, North Dakota

COLUMBUS LAGOON is a wastewater treatment facility located on County Road 5 in Columbus, Burke County, North Dakota. It serves a small population of 133 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard level for small communities in the United States under the Clean Water Act. The plant has a designed capacity of 113.56 megaliters and an annual discharge volume of 94.64 megaliters, indicating it operates below its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the North Dakota Department of Environmental Quality, which set effluent limits to protect water quality. The treated effluent is discharged into a local water body, likely a stream or creek that drains into the Souris River basin. This region is part of the Prairie Pothole Region, an ecologically important area for migratory waterfowl. The plant's operations help maintain water quality in this sensitive landscape.

The plant discharges into a local watercourse that flows into the Souris River, which eventually reaches the Assiniboine River and Lake Winnipeg in Canada. The surrounding Prairie Pothole Region provides critical habitat for migratory birds and supports diverse aquatic life. Proper wastewater treatment is essential to prevent nutrient pollution and protect downstream ecosystems.
