Water networks rely on various hardware components : meters, pumps, valves, pipes, pressure and level sensors made by different manufacturers and using different communication technologies. Water network management is expensive because it requires large deployments of workforces and many material resources, which are often spread over large territories, with limited accessibility, that need to be checked on a regular basis. Supervision is generally made through a combination of heterogeneous tools, such as SCADA systems, not really adapted to multi-site management. How to ease fleet management over these networks to support all key usages (remote meter reading, irrigation, network operations, hydraulic infrastructures monitoring…) ?
