Water is the most important emergency supply: you can survive weeks without food but only days without water. The best water storage containers are food-grade, sturdy, stackable or portable, and easy to dispense from. The common guideline is at least one gallon per person per day for several days. Here are the best water storage containers for every space, plus how to store water safely.

How I picked these

I’ve been into preparedness and survival for 13 years and spent 20 years hiking and 16 backpacking, and I’ve owned and used a lot of gear in that time. I know what works when it matters and what’s just marketing.

I compared these water storage containers on capacity, food-safe materials, durability, portability, stackability and how easy they are to fill and dispense from. Picks are based on that experience, manufacturer specifications and long-term owner feedback.

1. Scepter Water Container: best overall

Scepter’s military-style water cans are tough, food-grade and easy to carry, so you can store water at home and move it if you need to. They’re a favorite among preppers and overlanders.

Store several so you can rotate and transport water easily.

Where it falls short: each can holds less than barrels, so you’ll need several.

2. Augason Farms 55-Gallon Barrel: best for large storage

A 55-gallon barrel stores enough water for a family of four for about two weeks at the basic one-gallon guideline. Store it on a sturdy surface where it can stay.

Where it falls short: it’s too heavy to move when full, so you’ll need a siphon or pump.

3. 3.5 Gallon Stackable Jug: best stackable

Stackable jugs fit in closets and under beds, which makes them great for apartments. The spigot makes dispensing easy.

Where it falls short: they’re less rugged than military-style cans.

4. Bathtub Water Bladder: best for storms

A bathtub bladder lets you store a lot of clean water when you have warning, like before a hurricane. It stores flat and takes minutes to fill.

Where it falls short: you have to fill it before the water goes out.

5. Reliance Aqua-Tank: good alternative

Reliance makes some of the most popular water containers for camping and emergencies. Compare sizes and prices on the listing.

Where it falls short: check the size and current price on the listing before buying.

How much water should you store?

• At least one gallon per person per day, for drinking and basic sanitation.
• Store a minimum of three days; two weeks is better for home preparedness.
• Add more for pets, hot climates, nursing mothers and sick people.
• A family of four needs at least 12 gallons for three days, or 56 gallons for two weeks.

How to store water safely

• Use food-grade containers designed for water.
• Clean and sanitize containers before filling.
• Fill from a safe tap; treated city water stores well.
• Store in a cool, dark place, off concrete floors and away from chemicals.
• Label with the date and replace every six to twelve months, or use a water preserver.

Have a way to treat more water

Stored water runs out. A water filter or purification method lets you turn other water sources into safe drinking water. See our guide to the best survival water filters.

Make a simple family emergency plan

• Agree on a meeting place near home and one outside your neighborhood.
• Choose an out-of-area contact everyone can check in with.
• Store at least three days of water and food per person, plus pet supplies.
• Keep copies of important documents and some cash in your kit.
• Review your plan and rotate supplies every six months.

Water storage for apartments

• Use stackable jugs that fit in closets and under beds.
• Store cases of bottled water and rotate them into daily use.
• Keep a bathtub bladder for storms.
• Add a gravity filter for treating more water.

Build a 72-hour home kit

• Water: a gallon per person per day, plus a filter.
• Food: three days of no-cook or easy-cook food.
• Light and power: flashlights, a headlamp, batteries and a power bank or power station.
• Communication: an emergency radio and a written contact list.
• First aid and medications: including a week of prescriptions if possible.
• Sanitation: trash bags, wipes, toilet paper and a bucket.
• Documents and cash: in a waterproof bag.

Practice before you need it

Gear only helps if you know how to use it under stress. Test your equipment at home and on camping trips: run your power station through a night, start a fire with your ferro rod, use your radios on a hike, and pack and carry your go-bag around the block. Practice turns gear into real preparedness.

Water storage FAQ

How long can you store water?

Commercially bottled water often lasts years. For water you store yourself, the common guidance is to replace it every six months to a year, or use a water preserver.

Can I store water in milk jugs?

It’s not recommended; they degrade and are hard to clean. Use food-grade containers.

Should I store water on concrete?

Many people raise barrels on wood or a pallet to avoid heat and temperature swings.

How do I get water out of a 55-gallon barrel?

Use a siphon or barrel pump.

Can I drink water from a water heater in an emergency?

A water heater holds a lot of water and can be a backup source. Turn off the power or gas first and let it cool.

Do I need to add bleach to stored water?

Treated city tap water stores well without additives. Some people add a water preserver or a small amount of unscented bleach per official guidelines for long-term storage.

Which water storage containers should you buy?

Scepter military-style cans are the best water storage containers for most people because they’re tough and portable. Add an Augason Farms 55-gallon barrel for long-term home storage, and keep a bathtub bladder for storms.
