Helpful Information Providing Details and Information on Water Storage


Ever wondered to yourself why water storage is such a big deal? What’s so important about having a water filter on hand?

Read over the information below to get a helpful overview of water storage and purification, including essential gear you’ll need to prepare your own supply of water in case of an emergency.

  • When it comes to basic survival, water will keep you alive longer than food will.
  • You can survive without food for 14+ days, but only about 3 days without water.
  • An active adult needs a minimum of one gallon of drinking water per day.
  • You need a way to store enough clean water for you and your family long-term.
  • You should have 2+ methods to purify and/or filter water in case your supply becomes contaminated.
  • You need water you can carry with you, should you need to evacuate.

Take a look at the list below. You can see how water storage quickly becomes about more than just clean drinking water! Prepare a good supply in advance to meet your most essential needs in a disaster. In order of importance, you’ll need water to:

  1. 1. Drink
  2. 2. Prepare meals
  3. 3. Clean hands and cookware
  4. 4. Flush the toilet(s)
  5. 5. Bathe
  6. 6. Wash clothes

FEMA and The Red Cross recommend that you store a minimum of one gallon of water per person per day, which will only cover your most basic needs: drinking, some cooking, and minimal hygiene (think sponge bath). For anything beyond that, you’ll need to store additional water. And don’t forget water for your pets!

Store as much water as possible; aim for two weeks of stored water. Start small-enough for just one day-then build up to three days, one week, etc.

Good water storage options include food-grade emergency water barrels (or other containers like water tanks or jugs), boxed water kits you fill yourself, and pre-packaged water like emergency drinking water pouches or small, pre-filled water boxes. If you are an urban prepper or live in a hurricane-prone area, consider a temporary bathtub water storage system like the AquaPod.


Invest in a couple of different methods to purify and filter water, especially if you can’t have permanent water storage because of limited space.

  • water filter: microfilters are the best for removing as many microorganisms as possible from the water (a Katadyn water filter, like the Katadyn Pocket or Vario, is a great investment for your preparedness gear).
  • Chemical water purification/treatment options like the Aquamira Chlorine Dioxide treatment (for killing microorganisms that are too small for microfilters to catch).
  • A way to boil water (an alternative to chemical treatment)- a portable stove is a great option for this.
  • UV light treatment (disrupts the DNA of microorganisms, making it impossible for them to multiply in your digestive system).
