The RRVWS project is necessary to protect North
Dakota communities and economy from the devastating effects of drought. The emergency water supply to central and eastern North Dakota during times of water scarcity will protect public health, ensure ongoing economic vitality, and provide for environmental benefits in the river systems by augmenting the base flow of local rivers during periods of severe drought. With continued growth and industrial development, the RRVWSP is needed to mitigate against drought conditions that would cause costly water shortages, foster economic development by meeting municipal, industrial, and rural water demands, and promote environmental sustainability.
PROGRAM ENTITIES A project of this nature and size involves many entities to execute. As the key program stakeholders, Garrison Diversion represents the state and Lake Agassiz Water Authority the multiple cities and local water districts in central and eastern North Dakota and Minnesota. From an implementation standpoint, Black & Veatch
Corporation (BVCI) and Advanced Engineering and Environmental Services, LLC (AE2S) have provided program management, engineering design, and construction administration and inspection services
for the multitude of project components. Several components of this program require compliance with U.S. Army Corps of Engineers (USACE) permits, which has been coordinated between KLJ Engineering and the U.S. Fish & Wildlife Service (USFW) and the U.S. Department of the Interior, Bureau of Reclamation (Reclamation). To construct these components, various general
contracting, foundations, and trenchless construction firms such as Michels Trenchless, Garney Companies, Industrial Contract Services, Industrial Builders, and Minger Construction Companies have been instrumental.
PROGRAM COMPONENTS When in service, the greater program will withdraw water from the Missouri River and convey it to the Main Pumping Station (MPS) and water treatment facility near Washburn, ND. Raw river water will be treated at the MPS site to meet water quality standards established by the North Dakota Department of Health/Department of Environmental Quality requirements. Treated water will be conveyed via an approximately 165-mile, 72- inch diameter, multi-county pipeline system before discharging into the Sheyenne River. Lake Ashtabula will serve as a regulating reservoir, allowing controlled releases of the water as needed.
