Regent Lagoon Wastewater Treatment Plant, Regent, North Dakota

Regent Lagoon is a municipal wastewater treatment facility located in Regent, Hettinger County, North Dakota. It serves a small population of approximately 160 residents, reflecting the rural character of the area. The plant operates as a lagoon system providing secondary treatment, which is typical for small communities in the region. As a secondary treatment facility, Regent Lagoon meets the standard requirements under the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater discharges. The plant's design capacity of 113.56 m³/day and average discharge volume of 75.71 m³/day indicate it operates below capacity, allowing for future growth or seasonal variations. The treated effluent from Regent Lagoon is discharged into local waterways that ultimately drain into the Missouri River basin. The plant plays a key role in protecting local water quality in the semi-arid North Dakota landscape, where water resources are critical for agriculture and ecosystems. Proper treatment helps prevent nutrient pollution and maintains the health of downstream aquatic habitats.

Regent Lagoon discharges into local streams that are part of the larger Missouri River watershed. The Missouri River flows eastward through the Great Plains, eventually joining the Mississippi River and draining into the Gulf of Mexico. The surrounding region is characterized by agricultural land use, and the plant's secondary treatment helps reduce organic load and nutrients that could otherwise contribute to eutrophication in downstream water bodies. The semi-arid climate means that maintaining water quality in these intermittent streams is vital for local wildlife and livestock.
