7 liters out of 10 lost: Saulnières, a town in Eure-et-Loir faced with water leaks. According to a study by the Intercommunalités de France association, one liter in five of water is lost due to leaks on the network.

One solution: the complete renovation of the drinking water network, a responsibility of the urban area. “We have to rebuild the network at home, and they cannot do it alone,” explains President Gérard Sourrisseau.
