How to Store Water for Emergencies: The Complete Guide
The Most Critical Supply You’re Probably Neglecting
Most preppers spend hours researching guns and gear but give almost no thought to water storage. That’s a fatal mistake. You can survive weeks without food. You have 72 hours without water before things get critical.
Municipal water supplies are vulnerable — contamination events, infrastructure failure, power outages that knock out pumping stations. Every American household should have a water storage plan. Here’s how to build one.
How Much Water Do You Need?
FEMA recommends one gallon per person per day. That’s a bare minimum for drinking and basic hygiene. Real-world recommendation for preppers:
- Drinking: 1 gallon/person/day
- Cooking + hygiene: 1-2 additional gallons/person/day
- Pets: 1 quart per small dog, 1 gallon per large dog per day
For a family of four, plan on 8-12 gallons per day and build toward a 30-day supply minimum.
Water Storage Containers
WaterBOB Bathtub Bladder
One of the smartest tools available. When a disaster is imminent, fill this bladder in your bathtub and store up to 100 gallons of clean tap water. Costs under $30 and stores flat when not in use. Every household should own one.
7-Gallon Aqua-Tainer Jugs
Reliance Products makes the most popular portable water containers in the preparedness community. Stackable, BPA-free, with a built-in spigot. Buy several and rotate your supply every 6-12 months.
55-Gallon Barrels
For serious long-term storage. A single 55-gallon barrel with a hand pump and bung wrench gives you nearly a week of supply for a family of four. Store in a cool, dark location.
500+ Gallon Tanks
The next level. IBC totes (275-330 gallons) are available used from food distributors. Ideal for homesteads with space to store them.
Water Purification Methods
Stored water is a start. But you also need the ability to purify water from any source.
- Sawyer Squeeze Filter — Filters to 0.1 micron, removes bacteria and protozoa. 100,000 gallon rated life.
- Berkey Water Filter — The gold standard for home base filtration. Removes virtually everything including heavy metals and pharmaceuticals.
- Bleach — Regular unscented household bleach (6-8.25% sodium hypochlorite). 8 drops per gallon, wait 30 minutes.
- Water purification tablets — Aquatabs or Potable Aqua for portable use.
- Boiling — A rolling boil for 1 minute kills all pathogens. Simple and effective.
Common Water Storage Mistakes
- Using milk jugs (they degrade and leak within months)
- Storing near gasoline or chemicals (plastic is permeable to vapors)
- Not rotating your supply
- Forgetting to store a purification backup
- Ignoring your hot water heater (it holds 40-80 gallons of potable water in an emergency)
