Neche Lagoon Wastewater Treatment Plant - Neche, North Dakota

Neche Lagoon is a wastewater treatment facility located in Neche, a small town in Pembina County, North Dakota, United States. The plant serves a population of approximately 371 residents, reflecting its role as a small-scale municipal treatment system. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant utilizes a lagoon-based secondary treatment process, a common approach for small communities in the region. With a designed capacity of 151.42 megaliters per year and a current discharge volume of 113.56 megaliters per year, the facility operates below its design capacity. This suggests adequate capacity for current demand, with room for future growth. The treated effluent from Neche Lagoon is discharged into local surface waters that ultimately flow into the Red River of the North, which drains northward into Lake Winnipeg in Canada. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits, ensuring compliance with water quality standards to protect downstream aquatic ecosystems.

Neche Lagoon discharges into the Red River Basin, a major watershed that flows north through Manitoba, Canada, into Lake Winnipeg. The Red River is known for its flat terrain and seasonal flooding, which can influence nutrient transport and water quality. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream habitats that support fish species such as walleye and northern pike, as well as migratory waterfowl.
