Seamless leak detection process

This state-of-the-art leak detection system consists of a smart sphere equipped with sensors, with the ability to survey up to 35 kilometres of trunk mains in a single operation. It gets inserted into the live pipe network where it will be pushed by the flow within the pipe. Once inserted the orb is carefully tracked as it travels freely within the network. It verifies current conditions, detects leaks, air pockets, and other anomalies by recording acoustic data until extracted by the leak detection team. The collected data is then analysed. What sets this smart ball apart is it can be used in far-flung areas where it's difficult to do traditional active leak detection surveys.
