However, water is not produced in isolated systems under central control. The new model provides for a large ecological infrastructure as well as small local production units connected to a network able to integrate the production of fresh water and to supply it where needed. It's a Smart Water Network controlled by sensors that read the local lack of water and, through an Arduino board, activate the pumps providing the water where there is a peak of demand. The Smart Water Network will be a layer of the ecological network as well as the Smart Power Grid and the communications network. This strategy not only gives response to the preservation of the environment, but it is also a radically new model that ensures free and democratic access to the resources to everybody.
