Water is life. Sounds dramatic, but when a hurricane knocks out your municipal supply or an earthquake ruptures the main lines, that simple truth hits hard. The average person needs a minimum of one gallon per day for drinking and basic hygiene—and that’s the bare minimum. Factor in cooking, cleaning, and sanitation, and you’re looking at closer to three gallons per person daily.
So what’s the solution? Emergency water storage containers that can hold weeks or even months of water safely, keeping it fresh and ready when disaster strikes.
We’ve tested and researched the best options on the market, from bathtub bladders that hold 100 gallons to rugged military-style jerry cans built to survive anything. Whether you’re building your first emergency kit or upgrading your long-term water storage system, this guide covers everything you need to know.

How Much Water Do You Actually Need?
FEMA recommends storing at least one gallon per person per day for a minimum of three days. But let’s be real—three days won’t cut it in a serious emergency. A two-week supply is a more realistic starting point, which means:
- 1 person: 14 gallons minimum
- 2 people: 28 gallons minimum
- Family of 4: 56 gallons minimum
And that’s just for drinking and basic sanitation. If you’re planning for true off-grid scenarios or longer emergencies, aim for a 30-day supply or more.
Our Top 10 Picks for Emergency Water Storage
1. waterBOB Bathtub Emergency Water Storage Bladder — Editor’s Choice
The waterBOB is brilliant in its simplicity. When a storm warning hits, you fill your bathtub, slip this food-grade bladder inside, and suddenly you’ve got 100 gallons of clean drinking water protected from contamination.
Unlike filling an open tub (which gets dirty fast and can’t be used for drinking), the waterBOB keeps your emergency supply sealed and sanitary. The included hand pump makes dispensing easy, and the whole thing stores flat when not in use.
Pros:
- Massive 100-gallon capacity
- Food-grade, BPA-free material
- Keeps water fresh for up to 16 weeks
- Stores flat—takes almost no space
- Includes hand pump for dispensing
Cons:
- Single-use design (not meant for refilling)
- Requires a bathtub (not for apartments with only showers)
Why we love it: For hurricane and disaster prep, nothing beats the waterBOB’s convenience. You go from zero water storage to 100 gallons in under an hour.
2. Augason Farms 55-Gallon Water Storage Barrel — Best Large Capacity
When you’re serious about long-term water storage, the 55-gallon barrel is the gold standard. Augason Farms builds these from thick, BPA-free HDPE plastic specifically designed for potable water storage. The blue color blocks light (preventing algae growth), and the two-inch bung openings make filling and dispensing straightforward.
These aren’t just for preppers—they’re the same barrels used by emergency management agencies and humanitarian organizations worldwide.
Pros:
- True long-term storage (5+ years with proper treatment)
- Thick, durable construction
- UV-resistant blue plastic
- Standard bung fittings for pumps and siphons
Cons:
- Heavy when full (~450 lbs)
- Requires hand pump or siphon to dispense
- Not portable once filled
Why we love it: If you have the space, a 55-gallon barrel gives your family nearly two weeks of water security. Stack two or three, and you’re looking at a month or more.
3. Scepter 5-Gallon Military Water Container — Best Portable Option
This is the exact same jerry can design used by military forces around the world. The Scepter’s rugged construction handles drops, impacts, and extreme temperatures that would crack cheaper containers. The stackable design lets you store multiple cans efficiently, and the built-in handle makes carrying 40+ pounds of water manageable.
Pros:
- Military-grade durability
- Stackable design
- BPA-free food-grade plastic
- Multiple size options (5, 10, 20 liters)
- Comfortable carrying handle
Cons:

- Smaller capacity than stationary options
Why we love it: When you need to move water—to a vehicle, shelter, or different location—nothing beats the Scepter’s combination of durability and portability.
4. WaterStorageCube Collapsible Container — Best Space Saver
Living in an apartment? Limited storage space? The WaterStorageCube collapses flat when empty, taking up barely any room in a closet or under a bed. When you need it, it expands to hold 5.3 gallons of water with a built-in spigot for easy dispensing.
The BPA-free material is food-grade safe, and the handles on all four sides make carrying simple even when full.
Pros:
- Collapses completely flat
- Built-in spigot
- Lightweight and portable
- Very affordable
Cons:

Why we love it: For emergency kits, camping, and apartment dwellers, the collapsible design solves the “where do I store this?” problem that stops many people from preparing.
5. Reliance Products Jumbo Tainer 2.0 — Best for Daily Use
The Jumbo Tainer 2.0 strikes an ideal balance between capacity and usability. At 7 gallons, it holds enough water to matter but remains manageable to carry (about 58 pounds when full). The reversible spigot works in multiple positions, and the wide-mouth opening makes filling and cleaning a breeze.
Pros:
- 7-gallon sweet spot capacity
- Reversible spigot design
- Wide mouth for easy filling
- Hideaway handle
- Made in USA
Cons:
- Not stackable
- Single handle can be tiring

6. Eagle 55-Gallon Plastic Drum — Best Industrial Grade
When you want a water barrel that will outlast you, Eagle delivers. These industrial-grade drums feature metal lever-lock lids that seal completely, thick HDPE walls that resist chemicals and impacts, and construction that meets UN/DOT specifications for hazardous materials (meaning your water is definitely safe).
Made in the USA with a focus on durability over aesthetics.
Pros:
- Bomb-proof construction
- Metal lever-lock lid
- UN/DOT certified
- Made in USA
- Works for water and dry goods
Cons:

Why we love it: If you’re storing water in a shed, garage, or anywhere it might take abuse, the Eagle drum handles conditions that would damage cheaper barrels.
7. Digury 5-Gallon Water Jug — Best Budget Option
Not everyone needs military-grade equipment. The Digury jug delivers solid water storage at a price that lets you buy multiple containers without breaking the bank. BPA-free plastic, leak-proof spigot, and comfortable handles make it a practical choice for building your first emergency water supply.

8. 60-Gallon Bathtub Bladder 2-Pack — Best Value
Two bathtub bladders for roughly the price you’d expect to pay for one. This pack gives you 120 gallons of total capacity—enough for a family of four for nearly a month of drinking water. Keep one in each bathroom, and you’ve got serious redundancy.
Pros:
- Two bladders included
- 120 gallons total capacity
- Food-grade BPA-free material
- Hand pumps included

Same Scepter quality as our #3 pick, but this version includes the reversible spout that makes pouring much easier. Flip it one way for controlled pouring, flip it the other for faster flow. For families who’ll actually use their water storage (not just store it), this convenience matters.
Pros:

- Included reversible spout
- Food-grade plastic
- Stackable design
- Multiple sizes available
Cons:
- Slightly more expensive than basic version
- Spout can get lost if removed

10. Water Preserver Treatment 2-Pack — Best for Long-Term Storage
This isn’t a container—it’s what keeps your water fresh inside any container for up to five years. The Water Preserver treatment eliminates the need to rotate your water supply every six months. Just add it when you fill your 55-gallon barrel and forget about it.
Pros:
- EPA registered and FDA approved
- Keeps water fresh for 5 years
- Works with any container
- Simple to use
- Two-pack treats 110 gallons

How to Store Emergency Water Properly
1. Use food-grade containers only — Never repurpose milk jugs, juice containers, or anything that held non-food products.
2. Keep containers dark — Light promotes algae growth. Blue or opaque containers work best.
3. Store in cool locations — Basements, closets, and garages (if temperature controlled) are ideal. Avoid direct sunlight.
4. Treat or rotate — Either use water preserver treatment for 5-year storage, or rotate your supply every 6-12 months.
5. Elevate from concrete — Place barrels on wooden pallets or boards to prevent chemical leaching and make inspection easier.
6. Label everything — Mark fill dates clearly so you know when to rotate or treat.
Frequently Asked Questions
How long can you store emergency water?
Tap water stored in clean, food-grade containers will stay drinkable for 6-12 months without treatment. With water preserver treatment, properly stored water lasts 5 years or more.
Is it safe to store water in plastic containers?
Yes, as long as you use food-grade, BPA-free plastic specifically designed for water storage. HDPE (recycling code #2) is the gold standard. Never use containers that previously held chemicals or non-food products.
How much water should I store per person?
FEMA recommends one gallon per person per day minimum. For realistic emergency planning, store at least two weeks’ worth (14 gallons per person), ideally a month’s supply (30 gallons per person).
Can I store water in my garage?
Yes, but with precautions. Keep containers off concrete (use pallets), away from chemicals and gasoline, and protected from extreme temperature swings. Temperature fluctuations won’t make water unsafe, but they can affect taste and container integrity over time.
Do I need to add bleach to stored water?
For municipal tap water, no—it’s already chlorinated. For well water or uncertain sources, add 1/8 teaspoon (8 drops) of unscented liquid household bleach per gallon. Water preserver treatment is a more reliable alternative for long-term storage.
What’s the difference between water storage containers and rain barrels?
Rain barrels collect rainwater for gardening and are NOT food-grade safe. Emergency water storage containers are specifically designed for potable (drinkable) water with food-safe materials. Never use rain barrel water for drinking without proper filtration and treatment.
Final Thoughts
Building an emergency water supply doesn’t have to be complicated or expensive. Start with what fits your living situation—a collapsible container if you’re in an apartment, a 55-gallon barrel if you have garage space, or a bathtub bladder if you’re primarily concerned about hurricane prep.
The best emergency water storage container is the one you actually buy and fill. A single 5-gallon jug is infinitely better than the 55-gallon barrel you’ve been “meaning to get around to.”
Start small, build up over time, and you’ll sleep better knowing your family has water security regardless of what tomorrow brings.
