The waterBOB is a food-grade plastic bladder that lines a standard bathtub and holds up to 100 gallons of drinking water for emergency storage. You fill it from the tap before a storm or outage, and a hand pump siphons water out when you need it. It stores flat and weighs about 1.25 lb, so it fits in a closet or go-bag. Compared with barrels and jugs, it uses a tub you already have and holds far more water than a case of bottles, but it is single-use and only works when you have time to fill it before the water stops.

Owners who have used it in real outages treat it as a cheap insurance policy: it holds a large volume of water and stores away easily. Critics point out that it is one-use, depends on early filling, and that the plastic can be awkward to handle when full.
