Claim 18:
19. A method for detecting and evaluating anomaly events in a water distribution system, comprising:
using one or more sensors of the water distribution system to collect time series data that includes both flow and pressure measurements at a plurality of time steps;
decomposing, by a decomposition algorithm of an application executing on one or more computing devices, 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; and
based on the classification of at least one anomaly event, deploying maintenance or repair personnel to the at least one anomaly event.
