KULM LAGOON Wastewater Treatment Plant, LaMoure County, North Dakota

KULM LAGOON is a wastewater treatment facility located in Norden Township, LaMoure County, North Dakota, United States. The plant serves a small population of 354 residents, typical of rural lagoon systems in the Great Plains region. The plant provides secondary treatment, which is the standard required by the US Clean Water Act for municipal wastewater. With a designed capacity of 189.27 megaliters and an annual discharge volume of 151.42 megaliters, the facility operates within its capacity. US plants of this scale are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the North Dakota Department of Environmental Quality. The treated effluent is discharged to local surface waters, contributing to the watershed of the James River basin, which flows northward into the Red River of the North and ultimately into Lake Winnipeg. The plant plays a key role in protecting local water quality in this agriculturally intensive region.

The plant discharges into the James River basin, a tributary of the Red River of the North, which flows into Lake Winnipeg in Canada. This watershed supports diverse aquatic life and is an important migratory corridor for waterfowl. The region's flat terrain and agricultural runoff make proper wastewater treatment critical to preventing nutrient enrichment in downstream waters.
