Automated inspection systems for large underground concrete pipes partially filled with waste water

The Fraunhofer Institute for Factory Operation and Automation IFF has developed a comprehensive concept for inspection and cleaning systems for the sewer systems. This development was focused on the carrier systems for movement through the sewer line guaranteeing maximum recovery certainty, pipe axis measurement and integration of the sensor systems for detecting the condition of the sewer's gas and water spaces. This system involved a system for rough inspection of the sewer as well as cleaning systems and inspection system. The inspection systems, the sensor system and the cleaning technology used in this system is able to provide the inspection and cleaning required to meet the legal regulation in a one-pipe sewer.
