Allied Trenchless completed a challenging job in an urban metropolis.  The job required 13 separate liners between 42-48” in diameter.  Overall the team completed 3,658 linear feet of liner along with accomplishing the bypass in-house. Multiple phases of the project were established, all with their own challenges including lowering a wench approximately 40 feet onto the bridge for access. The bypass plan was extensive and required much prep work. Overall our bypass plan was over 3,660 feet of 18-inch pipe that went across the road. In order to keep up with the heavy rain, we had 4, 12-inch pumps as a backup. Allied was able to successfully complete the cleaning, bypass, and lining of this extensive project.
