Situated right in the heart of the Bakken oil boom in North Dakota, Watford City’s population 1,400 in 2006 has rapidly risen to nearly 3,000 according to the latest census. As part of this rapid growth, the North Dakota Department of Transportation (NDDOT) has gone to great lengths to accommodate the increase in traffic by undergoing several road improvements and expansion projects to handle the increased traffic of rigs, semis and large haul trucks now surging through the small town as part of this unexpected industrialization. As part of this effort, the NDDOT developed the Watford City Future Land Use Plan which incorporated a Long Range Transportation Plan making it one of the city’s biggest and newest roadway projects and would be built along ND Highway 23 from 6th Street to the ND Highway 23 Bypass. It would include new bypasses, expanded roadways and general roadway improvements to enhance traffic movement.

A state letting was issued, and the winning bid went to Knife River Corporation. While traffic detours and road construction was inevitable, Knife River had to meet an accelerated construction schedule and have Phase 1 completed by November 2015.  This construction phase also included a storm drain system. They looked to a highway drainage solution that could be quickly manufactured and installed along the main ND Highway 23 Bypass. Given the remote location and limited access to local manufacturing facilities in the surrounding areas, a mobile manufacturing solution seemed the best route to completing the storm drain system in the timeframe required.  Additionally, the elimination of over 75 truckloads of pipe from the highway and the need for a dedicated operator onsite to unload the pipe was an attractive alternative.  They selected Contech Engineered Solution’s MOBILE PIPE® mill to manufacture a polymer-coated ULTRA FLO® storm drain system and approach pipe onsite.

Working closely with Contech representatives to identify the ideal pipe material and diameters needed was easy. MOBILE PIPE can manufacture to the same exacting standards and quality of any of the Contech mills located across the country. This flexibility allowed the production of diameters ranging from 15 to 60 inches and included a polymer-coated ULTRA FLO® pipe section with reroll to accommodate the necessary joint tightness required in that area.

With over 14,680 LF (sections varying from 4,594 LF of 15-in diameter to 5,162 LF in 42-in diameter and 263 LF in 60-in), MOBILE PIPE offered the perfect flexibility for the variety of pipe diameters needed to complete the job. As part of the project plan, the NDDOT also required that rerolled pipe ends be used. The MOBILE PIPE reroll feature was a critical component making MOBILE PIPE a viable solution.

Project manager from Knife River, Grant Clingingsmith, LEED AP commented, "Contech Engineered Solutions has been very easy to work with on this project. All the pipe was ready to go when we needed it. Contech was flexible and available onsite to help with any issues. They were very responsive in getting additional materials to the jobsite.”

The entire project is scheduled to complete in 2016.
