Abstract
A water leakage position estimation system(S) configured to estimate a water leakage position in a pipe network including a plurality of pipe routes includes a water leakage determination unit () and an estimation unit (). The water leakage determination unit () determines whether a water leakage occurs in the pipe network based on a measured value of a vibration related to the pipe network that is acquired by a water leakage sensor () provided in the pipe network. The estimation unit () estimates, when the water leakage determination unit () determines that a water leakage occurs in the pipe network, a pipe route in which the water leakage occurs from the plurality of pipe routes based on the measured value and a predicted value of the vibration for each pipe route acquirable by the water leakage sensor () when a water leakage occurs in each pipe route.
