The paper describes a new methodology developed for model calibration and simulation of water distribution networks, starting from real time monitoring of pressures and flows throughout the system. In particular, the data recorded at the measurement stations are transmitted via GPRS to a server, archived in Oracle format, and used by the numerical simulator. Model calibration is based on a genetic algorithm running on a periodical basis within the simulator, in order to update the values of the coefficients representing the distribution of water losses. The application to a real network allowed to identify the areas with major problems, and to program leakage detection surveys and system rehabilitation, thus resulting in considerable water savings and reduction in pumping costs.
