We are currently installing a foundation system holding tank southwest of Washburn North Dakota for Missouri River water as a staging point before it will be pumped through a 6 foot diameter pipe across approximately 165 miles of pipe line east to the Cheyenne River south east of Cooperstown North Dakota. The water will be used to supply Fargo and Grand Forks in the times of flooding. The concrete foundation system will have an interior diameter of 44 feet with a depth of 74 feet. We will place 10.5 feet of concrete in the bottom of the foundation to act as plug and anchor system.
The progress of this project to date includes site preparation by clearing and grubbing, installation of security fence, buildup of roads and signage, and the installation of 40 – 5 foot diameter secant drilled shafts installed in a interlocking system approximately 85 feet below the working surface. We have just completed the excavation to an elevation of 74’ and have placed 3 feet of concrete at the base of the excavation.
