摘要

An essential element in many projects to rehabilitate buried pipe is the design and construction of a bypass system to carry flow during the period the segment being restored is out of service. In many instances, design and installation of the bypass is just as complex as the job of rehabilitating the pipe. A recent example is the bypass needed for cured-in-place pipe (CIPP) lining that involved 6,100 feet of 54-inch diameter reinforced concrete sewer pipe for a project for Jefferson County, AL. To accommodate required daily flow rates, the bypass system required five runs of 18-inch HDPE pipe totaling 18,500 feet and six 18-inch Sunbelt Quiet Flow pumps. The project owner was the Jefferson County Commission. Prime contractor was Layne Inliner, Sunbelt Rentals was the contractor for the bypass system and CH2MHill was the project engineer.
