Water leakages in pipelines and water distribution systems are the major issues in many countries. In this paper, we propose an automatic water pipeline leak detection device to continuously monitor the water pipelines to reduce manpower involvement. This device not only reduces human resource but also the time used to process collected information. Our device allows leak detection staff to remotely listen to leak sounds of any pipelines by focusing their attention on the suspicious area. The leak detection staffs can easily distinguish the real leakage from the false alarm by our system design. If leakage occurred, leak detection staffs will be able to determine the severity of the leak and its precise location. Our device is more effective and practicable for government agencies to implement to deal with the problem of water leakage.
