The water network management team in Nantes, France is responsible for maintaining supply from a highly complex system of underground water supply pipes. Constant road traffic and restricted access make monitoring, troubleshooting, and upgrading the water network exceptionally challenging.
The La Dopea (Direction des Opérateurs Publics de l'Eau et de l'Assainissement) leakage team was tasked with assessing the supply to one particular area of the Nantes Metropole area.
Initial investigations indicated substantial losses, but traditional leakage detection methods had failed to identify where these were. The business challenge was identifying and preventing these leaks.
