A methodology that establish the optimum water head pressure at the entrance of each hydraulic sector of the potable water distribution system, allow an efficient management and a free asset cost planning and operation of the network. Also reduces the commercial water losses (Non revenew water), reduces the amount of burst pipes, raises the pipes life time due a less operational pressure, and allows fast and easy identification of zones with commercial problems, spatial localization of users with consumption (0), spatial localization of zones with high rates of technical losses to detect leaks and illegal connections, renewal and rehab programs according to the real needs of the water distribution networks and long term assets investment and operational costs of the water distribution system.
