Oberon Lagoon Wastewater Treatment Plant, Oberon, North Dakota

Oberon Lagoon is a municipal wastewater treatment facility located in Oberon, North Dakota, a small town in Benson County. The plant serves a population of approximately 105 residents, making it a small-scale treatment operation typical of rural communities in the Great Plains region. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. It has a designed capacity of 75.71 cubic meters per day and currently discharges an average volume of 37.85 cubic meters per day. As a lagoon-based system, it relies on natural biological processes to treat wastewater before discharge. The treated effluent is released into local surface waters that drain into the Sheyenne River system, which flows northward into the Red River of the North and eventually into Lake Winnipeg. This watershed supports agricultural irrigation, wildlife habitat, and recreational activities, making proper treatment essential for protecting downstream ecosystems.

The plant discharges into local streams that are part of the Sheyenne River watershed, which flows into the Red River of the North and ultimately reaches Lake Winnipeg. This basin supports diverse aquatic life and is an important migratory corridor for waterfowl. The region's semi-arid climate and agricultural land use mean that maintaining water quality in these surface waters is critical for both ecological health and human uses such as irrigation and recreation.
