Fort Ransom Lagoon Wastewater Treatment Plant, North Dakota

Fort Ransom Lagoon is a municipal wastewater treatment facility located in Fort Ransom, Ransom County, North Dakota. The plant serves a small population of 77 residents, reflecting the rural character of the community. It is situated on Mill Road and operates as a lagoon system, a common treatment approach for small agglomerations in the region. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 37.85 megaliters per year and a discharge volume matching that figure, the facility operates at full capacity. As a US plant, it falls under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the North Dakota Department of Environmental Quality, which sets effluent limits to protect water quality. The treated effluent is discharged into local surface waters, likely tributaries of the Sheyenne River, which flows into the Red River of the North and eventually into Lake Winnipeg. The plant's location inland and away from coastal areas reduces direct marine impact, but its discharge contributes to the overall nutrient load in the Red River Basin, an ecologically sensitive region known for its prairie wetlands and migratory bird habitat.

The plant discharges into a local watercourse that drains into the Sheyenne River, a tributary of the Red River of the North. The Red River flows northward into Lake Winnipeg, a large freshwater lake that experiences eutrophication from nutrient runoff. The surrounding watershed is part of the Prairie Pothole Region, which supports diverse aquatic life and serves as a critical migratory corridor for waterfowl. The plant's secondary treatment helps reduce organic pollutants, but nutrient removal may be limited, contributing to downstream algal blooms.
