Claim Text:
1. A computerized method for determining one or more statistically likely geographical locations of an anomaly in a region or zone of a water utility network, the water utility network comprising at least a network of pipes for delivering water to consumers and a plurality of meters positioned within the water utility network including a plurality of meters capturing data regarding the water delivering within the region or zone of the anomaly, the method comprising: receiving anomaly event data, the anomaly event data representing an indication of an anomaly occurring or having occurred within a region or zone of the water utility network, the anomaly event data being associated with meter data produced by one or more of the meters; performing a plurality of tests on the anomaly event data each test designed to statistically determine a likely geographical location of the anomaly within the region or zone, the performance of each test producing a result indicating a likely location for the anomaly, wherein performing a plurality of tests comprises receiving data indicating a speed of propagation along the network for the detected anomaly and a time of detection for the anomaly and calculating the likely location of the anomaly by combining the time of detection for the anomaly and the speed of propagation to determine a location where differences between measured times of arrival match expected times of arrival; assigning a weight to each of the plurality of tests and weighting the result produced by each of the plurality of tests; combining the weighted results of the plurality of tests to generate scores for the determined likely locations for the anomaly, wherein the generated scores correspond to a probability that the anomaly occurred at the identified location; and presenting one or more of the determined likely locations to a user.
