Fargo WWTP - Municipal Wastewater Treatment in Fargo, North Dakota

Fargo WWTP is the primary municipal wastewater treatment facility for Fargo, North Dakota, serving a population of approximately 105,549. Located in the Red River Valley, the plant is situated near the Red River of the North, which flows northward into Canada. As a large agglomeration, the plant is subject to stringent federal and state regulations under the US Clean Water Act, administered by the North Dakota Department of Environmental Quality. Under the Clean Water Act, treatment plants serving populations over 100,000 are typically required to provide at least secondary treatment, with nutrient removal becoming increasingly important due to downstream impacts on Lake Winnipeg. The plant's discharge is permitted through the National Pollutant Discharge Elimination System (NPDES), which sets limits on biochemical oxygen demand, total suspended solids, and nutrients such as phosphorus and nitrogen. The treated effluent is discharged into the Red River of the North, which flows through Manitoba, Canada, and ultimately into Lake Winnipeg. This watershed is ecologically significant, supporting diverse aquatic life and serving as a critical migratory corridor for birds. Nutrient loading from upstream sources has been linked to algal blooms in Lake Winnipeg, making advanced treatment practices essential for protecting downstream water quality.

The plant discharges into the Red River of the North, which flows northward into Lake Winnipeg in Canada. The Red River Basin is a flat, agricultural region prone to flooding, and the river supports a variety of fish species including walleye and catfish. Downstream, Lake Winnipeg is a large, shallow lake that experiences eutrophication from nutrient runoff, making phosphorus and nitrogen control critical for the health of the entire watershed.
