In Episode 9 from Planet Underground TV, coming soon this June!
In St. Paul MN in 2010, a plumber called to unclog a sewer line at a home struck a gas line that had been installed through a sewer lateral to the home almost two decades earlier. A young woman lost her home as a direct result of the tragic accident.
An often overlooked, but critical part of damage prevention is cross bore mitigation. We’ll take you on a journey with the crews of Pipe View America and Blood Hound, honest and unscripted, as they dive into the important work behind sewer line inspections. One common thread is the great pride they take in safeguarding workers and the public.
These pre-construction sewer lateral inspections are designed to detect potentially dangerous cross bores by marking location and depth of all existing and abandoned sewer lines. Sophisticated automated cameras outfitted with sondes transmitting their location data probe the depths of sewer mains as a locator tech follows its progress from street level, communicating with the camera operator in their truck. A lateral launch camera is extended from the primary camera where the locator above ground detects the laterals’ locations off the sewer main. Once laterals are verified as clear of any cross bores or other debris, the collected depths and location information are passed along to the utility contractor conducting the planned trenchless excavation.
