I have some 5 gallon plastic military water cans. I want to use them to store water for the SHTF day. How long can water be stored??

If you add bleach to the water, it should be good up to two years.


Once you properly clean containers, fill them with potable, or safe, drinking water. All public water supplies are already treated and should be free of harmful bacteria. However, as an additional precaution, it is recommended that you add 5-7 drops, about 1/8 teaspoon, of chlorine bleach per gallon of water stored. This precaution protects you against any lingering organisms in storage containers that may have been inadvertently missed during the cleaning process.

Depends on the kind of container and what you do to treat the water.
We've got (2) 55 gallon food grade water barrels (blue kind) and I treat the water w/ Purogen about ever 6 months and about once a year dump the water and fill with new just for good measure. This is part of our proverbial "defication hitting the bladed oscillating machine" supply. Bleach will also work but tastes like ass. There are several other options.

If you put too much bleach in the water, it will taste like, well, bleach. If you use the proper amount of bleach, you won't taste the bleach. I have used the bleach method for a LONG time.

You can also use food grade hydrogen peroxide, it is excellent for treating water. Use four drops of hydrogen peroxide to a quart of clean water. Water treated with hydrogen peroxide will last several years longer than any other treatment method.

Water will last indefinatly, stored properly with bleach. But why not just replace it once a year? Thats exactly what I do.

Isn't bleach bad for you.. Granted we're not talking about hitting the bottle itself, but still.

Bleach will off gas rapidly. If you have too much bleach all you have to do is let it set and the taste will go away.

If you're wanting very long term storage with minimal caretaking, I can sell you some dehydrated water. It's extremely concentrated and has an indefinite shelf life.
