PROBLEM TO BE SOLVED: To provide a water tank securing fresh water capable of coping with disaster.SOLUTION: A box body 3 in which a long thin water conducting pipe 4 is tightly folded and packed is installed midway between a water meter and a faucet. As all daily household supply water runs through the water conducting pipe 4, water exchange or antiseptic agents are not necessary and fresh water runs to be stocked in the box body 3 until an instance of disaster. When the box body 3 tilts or collapses from a normal installation position due to the disaster, inlet/outlet pipe is shielded instantaneously and the fresh water in the box body 3 is secured without leaking until the water is used. |
