McClusky Lagoon Wastewater Treatment Plant - McClusky, North Dakota

McClusky Lagoon is a municipal wastewater treatment facility located in McClusky, North Dakota, serving a small population of 380 residents. The plant provides secondary treatment, a standard level for small communities in the United States, and operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for all point source discharges. The plant has a designed capacity of 189.27 cubic meters per day and discharges a similar volume of treated effluent. As a lagoon system, it likely uses natural biological processes for treatment, common in rural areas with lower population densities. The facility is inland, more than 50 kilometers from the coast, reducing direct marine impact. The treated wastewater is discharged into local water bodies within the Missouri River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. The plant's operations help protect local groundwater and surface water quality in the semi-arid region of central North Dakota.

The plant discharges into the Missouri River watershed, which flows through the Great Plains and into the Mississippi River, eventually reaching the Gulf of Mexico. This region supports diverse aquatic life and is important for migratory birds. The plant's secondary treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
