Anomaly detection in wastewater networks
A computer complemented method for detecting anomalies e.g. blockages and leaks, at a wastewater asset e.g. a manhole, pumping station, of a wastewater i.e. sewer network, wherein the asset has a sensor configured to detect metrics associated with flow rate at the asset. The method acts on the sensed water flow data and current rainfall data from existing systems to provide an alert of an anomaly, by using machine learning, trained on historic flow and rainfall data, to predict max and min expected thresholds for flow metrics based on current rainfall data, and if the sensor measurements are outside these thresholds, during a predetermined duration, an alert is sent indicating an anomaly to a sewage network operator. This may improve the ability to efficiently manage a sewer network, preventing unnecessary inspection and/or reduce maintenance schedules, and allow specific maintenance to reduce use of overflows as a result of e.g. blockage, reducing risk of contamination of waterways. Also claimed is computer/system/program for carrying out the computer implemented method.
