Abstract: PROBLEM TO BE SOLVED: To utilize water left in a receiving tank effectively at the time of a disaster by sensing the quakes of an earthquake by a quake detector installed to a building structure and stopping the supply of water through a pump or a feed valve by a controller. SOLUTION: When an earthquake is generated, a quake detector 20 senses quakes, a signal is transmitted to a controller 23 through an electric circuit 24 from the quake detector 20 when the quakes exceed predetermined quake intensity, and the operation of a pump 10 is stopped. Each faucet 7 is closed manually, and the low-pressure water supply operation of the pump 10 is started by the controller 23. When a flow meter 21 senses a flow rate at that time, leakage at any place in a distributing pipe 12 is considered because all of the faucets 7 are closed. The pump 10 is stopped at that time, and the place of leakage is repaired temporarily. Accordingly, leakage from the place of damage and a secondary disaster with the leakage can be prevented.
