Abstract: Title: System for Soil-Adaptive Acoustic Leak Detection and Pipe Health Monitoring Using Distributed Fibre-Optic Sensing The present invention relates to an acoustic leak detection and pipe health monitoring system for underground water distribution networks. An optical fibre (101) positioned in sensing proximity to an underground water pipeline is interrogated using distributed acoustic sensing (102) to acquire spatially distributed vibration information. Acoustic information derived from the sensing signals is analyzed using a soil-adaptive acoustic model (104) selected according to a soil condition associated with a monitored pipeline region to classify leakage and non-leakage events. A detected leakage event is confirmed and localized by mapping a sensing-fibre position to a corresponding pipeline segment and geographical location. A pipe health assessment unit (107) generates a segment-wise Pipe Health Index based on current and historical condition parameters. A maintenance automation unit (108) evaluates the classified event and Pipe Health Index with pipeline asset information and generates a maintenance work order comprising location, pipe-condition and maintenance information upon satisfaction of a maintenance criterion.
