Drinking water storage device and method

A device for storing fresh water inside of a bathtub, the device comprising:

• a flexible bladder liner;
• the flexible bladder liner taking on a shape of the bathtub when the flexible bladder is filled with water;
• the flexible bladder liner surrounding the water on all sides;
• the flexible bladder liner including a plurality of seams;
• the plurality of seams allowing the flexible bladder liner to fold to fit into a box, while also allowing the flexible bladder liner to expand to fit the shape of the bathtub when the bladder liner is filled with water;
• a first aperture through the flexible bladder liner;
• a second aperture through the flexible bladder liner;
• a pump affixed to the first aperture;
• a cap affixed to the second aperture;
• whereby the flexible bladder liner is filled with water prior to a time of emergency, thus preserving fresh water for drinking in an event of a water shortage;
• a siphon pump formed from:
• an intake line;
• a collar;
• a pump bulb;
• a release valve;
• an outlet tube;
• whereby squeezing the pump bulb pushes water through the outlet tube, and releasing the pump bulb draws water into the outlet tube, thereby filling the flexible bladder liner.
