This paper introduces a newly developed system for locating leaks in water distributionnetworks. The system is based on the cross-correlation method and is realized insoftware for personal computers (PCs). It utilizes multimedia components of PCs torecord and playback leak sounds in water pipes. It also incorporates several signalprocessing and analysis innovations, in particular an enhanced cross-correlationfunction. The new system is readily integrated with commercially available wirelessdata transmission units and vibration sensors to provide a complete leak detectionsystem. Advantages of the new system are low cost, flexibility and improved accuracy.Features of the system, details of its various modules, and a demonstration of itsaccuracy are presented.
