HOW DO YOU SOLVE A PROBLEM LIKE A CROSS BORE?

摘要

For a plumber hired to clear a clogged sewer line, a cross bore can be a catastrophic event. Rotating cutting tools designed to clear roots and debris from a sewer lateral can easily cut through a utility line placed with horizontal directional drilling (HDD) trenchless technologies. How does the plumber eliminate the risk associated with not knowing what has clogged the line? More importantly, how can the utility line be initially placed without compromising existing underground facilities such as a sewer lateral? The cross bore problem is really two different and distinct challenges: preventing cross bores during the installation of new facilities using trenchless technologies, and recognizing when an existing cross bore exists in order to safely mitigate. Each problem has its own set of risks and steps to mitigate risk.
