HOOPLE LAGOON Wastewater Treatment Plant, Hoople, North Dakota

HOOPLE LAGOON is a municipal wastewater treatment facility located in Hoople, Walsh County, North Dakota. It serves a small population of 242 residents, reflecting the rural character of the area. The plant operates as a lagoon system, a common treatment method for small communities in the region. The plant provides secondary treatment, which meets the minimum standard for municipal wastewater under the U.S. Clean Water Act. With a designed capacity of 151.42 ML/year and an actual discharge volume of 75.71 ML/year, the facility operates at about 50% of its capacity. This suggests adequate headroom for future growth or seasonal variations. The treated effluent is discharged into local surface waters that drain into the Red River of the North, which flows northward into Lake Winnipeg in Canada. This watershed is part of the larger Hudson Bay drainage basin. The plant's operation helps protect downstream water quality in this ecologically sensitive prairie river system.

The plant discharges into tributaries of the Red River of the North, which flows through the fertile Red River Valley into Lake Winnipeg. This watershed supports diverse aquatic life and is an important migratory corridor for waterfowl. The region's flat terrain and cold winters require careful management of nutrient loads to prevent eutrophication in downstream lakes.
