  Slide Rail, Linear Multiple Bay, was used to expose one 108" force sewer main. The goal was to bypass the sewer main with three smaller pipes so that a leak could be repaired. The widest section was 34' x 60' x 12'.

  The 4' panels are installed next, then the pit will be dug another 4' deeper.

  Next, prepwork begins on the 108" force main so that it can be tapped and detoured. This will allow for the repairs to be conducted.

  The valves that fit to the top of the pipe had to be reformed to fit. They also have to finish pouring concrete around the valve bodies.

  Soon as they get another valve, they will start to bypass next Tuesday.
