Bismarck WWTP - Municipal Wastewater Treatment in Burleigh County, North Dakota

Bismarck WWTP is a municipal wastewater treatment facility located in Burleigh County, North Dakota, serving an estimated population of 61,272. The plant is part of the region's essential water infrastructure, handling domestic and industrial wastewater from the Bismarck-Mandan metropolitan area. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal facilities of this scale. NPDES permits issued by the North Dakota Department of Environmental Quality govern discharge limits and monitoring requirements to protect water quality. The treated effluent is discharged into the Missouri River watershed, which flows southward to the Mississippi River and ultimately to the Gulf of Mexico. The plant plays a key role in maintaining water quality in this major river system, supporting downstream aquatic habitats and recreational uses.

The plant discharges into the Missouri River basin, a major tributary of the Mississippi River that drains into the Gulf of Mexico. The Missouri River supports diverse aquatic life, including endangered species such as the pallid sturgeon. Downstream ecosystems rely on effective nutrient removal to prevent algal blooms and hypoxia in the Gulf.
