Hope Lagoon Wastewater Treatment Plant, Steele County, North Dakota

Hope Lagoon is a wastewater treatment facility located in Hugo Township, Steele County, North Dakota, serving a small population of 258 residents. The plant operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 151.42 megaliters and an annual discharge volume of 75.71 megaliters, the facility operates well within its capacity. As a small agglomeration, it is subject to state-level NPDES permitting under the EPA's delegated authority. The treated effluent is discharged into local waterways that drain into the Red River Basin, ultimately flowing north to Lake Winnipeg in Canada. The plant plays a key role in protecting the region's surface waters from nutrient pollution and pathogens, supporting downstream aquatic ecosystems and agricultural water uses.

The plant discharges into the Red River Basin, which flows northward through North Dakota and Manitoba into Lake Winnipeg. This watershed is ecologically sensitive due to nutrient loading concerns that contribute to algal blooms in Lake Winnipeg. The plant's secondary treatment helps reduce organic and nutrient loads, protecting the riverine habitat and downstream lake ecosystem.
