Document Type and Number:
WIPO Patent Application WO/2020/246182
Kind Code:
A1
Abstract:
A management system comprising a storage device and a control unit, the management system managing a duct line network that supplies water to users via a duct line. The storage device stores the first time-series data of yearly cases of water leakage from duct lines occurring in the duct line network and the second time-series data of yearly water leakage cases calculated from the amount of water consumed yearly and the amount of water delivered yearly. The control unit statistically processes the first and second time-series data stored in the storage device and obtains the leakage loss of water per case from the duct lines.
