Lansford Lagoon Wastewater Treatment Plant, Lansford, North Dakota

Lansford Lagoon is a municipal wastewater treatment facility located in Lansford, North Dakota, serving a small population of 245 residents. The plant operates as a lagoon system providing secondary treatment, which is typical for small communities in the rural Great Plains region. The plant has a designed capacity of 75.71 million gallons per year and discharges a matching volume, indicating full utilization. As a secondary treatment facility, it meets the minimum requirements under the US Clean Water Act for small communities, with effluent standards set by the North Dakota Department of Environmental Quality. The treated effluent is discharged into local surface waters that drain into the Souris River basin, eventually reaching the Hudson Bay via the Nelson River system. The plant plays a key role in protecting downstream water quality in this agriculturally intensive region of North Dakota.

The plant discharges into local streams that flow into the Souris River, which crosses into Canada and ultimately drains into Hudson Bay. The surrounding watershed is primarily agricultural, with row crops and livestock operations. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream aquatic ecosystems and drinking water sources in both the US and Canada.
