This paper introduces a newly developed system for locating leaks in water distribution networks. The system is based on the cross-correlation method and is realized in software for personal computers (PCs). It utilizes multimedia components of PCs to record and playback leak sounds in water pipes. It also incorporates several signal processing and analysis innovations, in particular an enhanced cross-correlation function. The new system is readily integrated with commercially available wireless data transmission units and vibration sensors to provide a complete leak detection system. 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 its accuracy are presented.
