WaterB.O.B.:

The WaterBOB™ turns any standard bathtub into an emergency water reserve, storing up to 100 gallons of fresh drinking water. Water stored in an open bathtub, with dirt, soap film and exposure to debris will spoil quickly and become useless.

When an emergency arises simply lay the WaterBOB™ in your bathtub, hookup to the faucet and fill to capacity. A siphon pump is included to easily dispense the water into jugs or pitchers. The WaterBOB™ follows FDA guidelines and is constructed of heavy-duty food grade plastic.

Living in Souther California and having gone through a couple major Earthquakes, we can pretty much say that this is a great idea®. For $22.95 you just can't go wrong here folks.
