The UN water report, published in 2015, is alarming: before 2030, the worldwide resource shortage of water (all consumptions included) would achieve 40 %. For companies and water managers of the networks of drinking water, the issues are highly critical: it is about to manage intelligently water ressources, fighting against the waste and water losses.
It is one of the biggest challenges for Big Data today: shifting from an intuitive management of water resources to a scientific one in real time.
Thanks to GPS, to sensors' networks, to mobile phones, we can already collect with efficiency and at a lower cost masses of data on water systems and assure so an optimization of the maintenance.
Some French cities are going further : Montpellier creates a web portal which aims to consolidate the consumptions and to decrease the time between the location and the repair of leaks.
Montpellier relies on Big Data too to monitor the senior health status by following their consumption of water hour by hour.
But the most advanced are the Netherlands that has one the best monitored water system in the world. Thanks to Big Data and to a revolutionary program named Digital Delta, local authorities are able to take into account extrem meteorological phenomemenon particularly, to better plan the risks of flood, drought, but also the quality of the water, while reducing its management costs of 15 %.
