An analysis model of the daily water demand

The analysis of the functioning of a distribution network and the user request characterization assumed more and more importance in carrying out Law 36/94 provisions aiming to water saving, to guarantee service minimum levels, as well as the management of water supply systems, according to features of efficiency, efficacy and economy. This paper presents a methodology which allows an organic approach in the functional analysis of a water supply network, with a time dependent demand characterization; it allows to describe in a compact way the functioning levels and, at the same time, to supply service commitment units with useful instruments for a right management. Such an analysis procedure, through the continuous monitoring of the distributed water, allows the dynamic control of the water supply system functioning and the interpretation of time-capacity diagrams registered in relevant points of the networks. The study, developed according to the Theory of signals, has allowed to divide registered diagrams into simple harmonics, by identifying the comparison parameters, Amplitude, Frequencies and Phases, for realities belonging to the same territorial area. The results, encouraging for the generality of the proposed methodology, allow an extension of the application to distribution systems inside the same A.T.O. or not.
