1. A method for identifying the source of pressure transients in a water distribution network comprising a plurality of high-frequency pressure sensors installed therein, said method comprising:
an acquisition step to acquire a plurality of pressures values for each high frequency pressure sensor during a preset time limit, said plurality of pressures values defining a sampled pressure variation record nearby each sensor during said preset time limit;
a detection step for detecting transient events amongst the sampled pressure variation record, wherein every detected transient event is associated with a corresponding signature;
a grouping step for grouping detected transient events in the sampled pressure variation record; the transient events corresponding to the same signature being grouped together; and
a localization step for localizing the source of said grouped transient events in function of said sampled pressure variation records, comprising a cross-checking sub-step comparing said grouped transients with external information data received from at least one other device cooperating with said water distribution network, in order to correlate a group of transient events with a cooperating device operation; the external information data comprising a least information related to a pump operation and/or a valve operation and/or an important customer consumption and/or a fire hydrant operation.
