Abstract
A water leak sensing system includes: a plurality of sensor terminals including a sensor installed in a pipeline of a water supply network; and a computer that senses a water leak from the pipeline based on detection signal data of the plurality of sensors of the plurality of sensor terminals, and outputs a result. The pipeline is either a first pipeline not covered by a pipe covering member (PE sleeve) or a second pipeline covered by the pipe covering member. The sensor can detect a signal at a first distance from a water leak point when the water leak occurs in the first pipeline, and detect a signal at a second distance, longer than the first distance, from the water leak point when the water leak occurs in the second pipeline.
