Bypassing the flows to the treatment plant proved to be problematic as the 66” influent line ran under an existing canal, but the crews designed and constructed a temporary bypass to control flows to allow for installation of the liner pipe. M&H resolved numerous design issues to facilitate construction including adjusting the location of the insertion pit. These changes helped both the City of Davis and McGuire and Hester expedite the project.
The scope of this project consisted of: cleaning the 66” Influent Sewer, plugging and temporary bypassing, or flow control, TV-inspection of sewer line, excavation for insertion and winching pits, pipe-bursting a section of the existing 66”, inserting 42-inch HDPE slip-liner pipe, and grouting annular space between host and slip liner. Our crew also installed, maintained, and abandoned maintenance holes and constructed a maintenance access road.
