Sewer Force Main Electromagnetic Inspection Robotic Crawler

In August 2011, Pure Technologies brought out the redesigned PureRobotics wastewater crawler unit to conduct an electromagnetic inspection on a 42-inch (1050mm) sewer force main for a major utility in Ontario, Canada. Pure was able to inspect 3,400 feet from a single access in both directions of the line. New improvements to the tracks assisted in pushing the crawler through the heavy debris at the bottom of the pipe that would otherwise entrap other robotic inspection systems.
