Emerado Lagoon Wastewater Treatment Plant, Emerado, North Dakota

Emerado Lagoon is a municipal wastewater treatment facility located in Emerado, North Dakota, serving a small population of 414 residents. The plant provides secondary treatment, a standard level for small communities in the United States, and is situated in the rural Red River Valley region. The plant has a designed capacity of 264.98 megaliters and discharges approximately 227.13 megaliters of treated wastewater annually. As a US facility, it operates under the Clean Water Act, with discharge permits issued by the North Dakota Department of Environmental Quality or the US EPA, ensuring compliance with water quality standards. The treated effluent is released into local waterways that drain into the Red River of the North, which flows northward into Lake Winnipeg in Canada. This watershed supports diverse aquatic life and is an important ecological corridor in the northern Great Plains.

The plant's discharge enters the Red River of the North basin, which flows through agricultural and wetland areas before reaching Lake Winnipeg. This watershed is ecologically sensitive, supporting migratory birds and fish species. The Red River's flat terrain and seasonal flooding influence nutrient transport and water quality downstream.
