Abstract

One great challenge for waterworks is effective leakage detection. This paper presents a method based on the self-organising map for leakage detection in a water distribution network. The data used for training and validating the test results consist of vectors of the flow meter readings and knowledge of reported leak locations. The most important factor facilitating the self-organising-map-based modelling of leaks is the developed leak function. The results of the experiments presented show that the model trained on flow data can detect leaks in a defined distribution network area.
