Active Leakage Control with WDNetXL

Abstract

Water losses in Water Distribution Networks (WDNs) are classified in background and burst outflows. Bursts are generally the natural evolution of background leakages, driven by external factors that entail major water outflows, generating changes of WDN hydraulic functioning, detectable as anomalies in monitored flow/pressure data. Active leakage control strategies aim at prompt detection, localization and repair of pipe burst, thus reducing possible damages to private/public properties, minimize unplanned works, and reduce volume of lost water.This contribution presents the novel Leakage Control module of the WDNetXL system, aimed at supporting various active leakage control actions ranging from the design of effective pressure sampling system up to prioritizing of possible failed pipes to survey.
