Usually used as surveillance instruments by law enforcement agencies, drones can also be used to inspect city pipes. They are able to enter places that are inaccessible or dangerous for technicians.

But sometimes it is impossible to go through the pipes. This is where the drones, protected by a cage, in order to avoid obstacles for the aircraft. In 8 minutes, the machine will inspect 200 meters of pipelines. “We’re gonna be faster than a team of four“, rejoices Benjamin Hardouin, video operator.
How to do when neither the man nor the drone cannot access the pipes? In Bordeaux (Gironde), technicians use droneso-called crawling. They allow you to walk independently and take pictures every ten seconds. “We have, over seven years, mapped 300 km of network, which will allow the metropolis to have a complete state of heritage“, affirms Xavier Lava, Network Department Director SABOM.
