The hot water heater 5f receives supply of propane gas 8b from a cylinder 8a installed outside the management building 5h, and burns it to produce hot water.

  In the event of a disaster such as an earthquake or flood, the first pump 3 that is normally used in a power failure does not operate even though there is water in the water receiving tank 2, and the water in the water receiving tank 2 cannot be used. In addition, a temporary toilet is necessary because water cannot be poured into the toilet bowl. However, a sufficient number of temporary toilets cannot be secured in a wide-area disaster. Temporary toilets are not preferred because they are drawn up.

  Therefore, the invention of Patent Document 1 is disclosed as a technique that can continue to use the water in the water receiving tank even if a water supply pump that is normally used cannot be used due to a disaster or the like.

In the invention of Patent Document 1, when a power failure occurs due to a disaster such as an earthquake or a fire, the power failure stored in the water receiving tank can be supplied to each room of the building by using a small and simple facility. A water supply device for time and a water supply method at the time of power failure,
A water receiving tank 21 arranged in the basement 11 of the building 12, a water supply line 22 connected to each room and the water receiving tank 21 of the building 12, and supplying the water A in the water receiving tank 21 to each room, and manually It has a valve 46 with a decompression function that can be opened and closed, and includes an inert gas supply container 24 that supplies an inert gas at a predetermined pressure to the gas phase B of the water receiving tank 21.

  Patent Document 1 is a small-sized water receiving tank, which may be possible for a short time. However, if the water receiving tank has a large capacity, a large amount of special inert gas is always provided in order to apply sufficient pressure. There is a problem that needs to be addressed. In addition, there is a problem in the stable supply of such special gas during a disaster.
