Overview
Anamoose Lagoon is a secondary wastewater treatment plant serving 227 residents in Anamoose, North Dakota. It discharges treated effluent into local waterways under US EPA NPDES regulations.
Anamoose Lagoon is a municipal wastewater treatment facility located at 698 Main Street in Anamoose, McHenry County, North Dakota. The plant serves a small population of 227 residents, reflecting the rural character of the community. As a lagoon-based system, it provides secondary treatment to meet state and federal water quality standards. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. With a designed capacity of 113.56 million gallons per year, the facility manages the community's wastewater through natural biological processes in aerated lagoons. The treatment process relies on settling and biological degradation to reduce pollutants before discharge. The treated effluent is released into local surface waters that drain into the Souris River basin, ultimately flowing north into Canada and toward Hudson Bay. The plant's location in the Great Plains region means it must manage seasonal temperature variations that affect lagoon performance. Proper treatment protects downstream aquatic habitats and groundwater quality in this agricultural region.
Environmental context
The plant discharges into local streams that are part of the Souris River watershed, which flows northward through North Dakota into Manitoba, Canada, and eventually reaches Hudson Bay. This semi-arid region relies on surface water for irrigation and livestock, making effluent quality critical for maintaining aquatic life and preventing nutrient enrichment in downstream water bodies.
