Claim 0:
1. A method for detecting and evaluating anomaly events in a water distribution system, comprising:
receiving, by an application executing on one or more computing devices, time series data that includes both flow and pressure measurements at a plurality of time steps from one or more sensors of the water distribution system;
decomposing, by a decomposition algorithm of the application, the time series data to remove seasonality and render the time series data stationary;
detecting, by one or more statistical process control (SPC) algorithms of the application, outliers of the stationary time series data;
classifying, by the application, sensor events in response to flow or pressure of detected outliers exceeding high or low thresholds for at least a given number of time steps;
classifying, by the application, anomaly events by correlating one or more sensor events related to flow with one or more sensor events related to pressure;
determining, by the application, a quantitative score for each of the detected anomaly events that indicates a level of significance or importance; and
providing, by the application, at least the detected anomaly events and their respective quantitative scores.
