For most households, sealed bottled water is the simplest reserve; portable food-grade jugs are easier to move, while large drums save repeated trips but need space and a pump. A bathtub bladder is a short-notice option, not a substitute for stored water you can access before a storm.
The right container depends on where it will sit, who must move it and when you can fill it. CDC recommends storing at least one gallon per person per day and using clean, food-grade containers if you fill them yourself. For the water quantity and treatment steps, see the emergency water storage guide.
Choose by access
| Container | Best fit | Trade-off to plan for |
|---|---|---|
| Sealed bottled water | Simple, distributed storage | Packaging takes more room; use by date on label |
| Small food-grade jug | Grab-and-carry supply | Heavy when full; closure and handle need inspection |
| Large food-grade drum | High-volume home reserve | Needs floor space, a stable location and a dispensing plan |
| Bathtub bladder | Filling after a warning | Requires lead time, a clean tub and access to tap water |
Water weighs about 8.3 pounds per US gallon, so avoid placing a full drum on a floor or shelf unless the structure is suitable. Store containers away from gasoline, pesticides, direct sunlight and heat. Do not use a container that held chemicals or food residue that cannot be cleaned.
Make self-filled storage traceable
Sanitize the container using CDC directions, fill it from a safe supply, label the date and inspect the cap and container periodically. CDC advises replacing self-filled water about every six months; follow the container maker’s instructions.
Avoid buying a container solely by advertised capacity. Confirm that it fits through the doorway, can be supported when full and can be opened or pumped without contaminating the water.

Common questions
What container is best for emergency water storage?
Choose sealed bottled water for simplicity, food-grade portable containers for manageable household storage, and a drum only if you have space and a safe way to access it.
Can I store water in any plastic container?
No. Use commercially bottled water or containers specifically made for food or drinking water, and follow CDC cleaning and storage directions.
Is a bathtub bladder long-term storage?
No. It is filled when a hazard is approaching, so it depends on having warning time and a clean usable bathtub.
