People tend to overthink this, and I am speaking from real experience. Just keep the requisite number of gallons of water you'd use in the timespan for which you're planning and change them every couple of years, just for the sake of doing it. They'll last for eons in reality.

In an emergency, water's great, but in a longer-term bad situation, it falls pretty far down the list. Unless you're in an unusually arid place, a means to obtain the water necessary to live (maybe not to shower, run the dishwasher or laundry though) will make itself known. And you'd never store enough to matter for *that* long, while a few gallons of cooking oil or a bag of salt would make you a local hero for a long, long time.

What people tend to really wish they'd planned for, but don't:

1) cooking oil
2) toilet paper, paper towels
3) spices, herbs, pepper and salt
4) sugar, chocolate (especially for its fat), candy, honey
5) soap, shampoo, cleaning products
6) seeds for easy-to-grow stuff
7) vitamins
8) if you can keep a couple of hens, you won't regret it.

Nothing's as tradeable (relative to effort) as eggs!

Aside from the last three, these things can be stored for a long, long time. And in reality, #6 and #7 would be good for a few years.

I am a Sarajevan who lived during the siege with no heat, electricity, water, phone (etc) for the most of a three-year period. What's on the list above is what I was almost always missing. We got "dry" food packages from various sources. These tended to be Truman eggs (good for a little protein, but thats about it), macaroni, rice, powder potatoes, Vietnam-era "biscuits" - supposedly with vitamins, but these were from the late 1960s and of dubious nutritional value.

What was missing was: fat, protein, flavor and variety. Boiling was the only way to cook things, due to lack of any cooking oils. To fry something was a rare miracle - even if you were frying reconstituted potatoes from powder. And to have a little pepper or salt was nirvana.

Authorities say complacent city dwellers need to learn from their regional cousins and have an emergency kit ready for when a natural disaster strikes, including three days' worth of water.

Renogy's rechargeable flashlight incorporates a host of useful features, including the ability to function as a backup battery for phones and other gadgets.

You probably already have most of the stuff you need.
