You don't need 2k calories a day in an emergency.

You can survive on 1200-1500 calories a day.

I still don't advise going in 100% on rice as beri-beri is an issue (or heavy metal issues if you go all brown rice).

A good mix of canned goods, dried goods and reliable water will help. Even in a shortage you will probably have some access, but limited access.

I strongly advise against bottled water for emergencies. It is the worst possible solution for cost/size/availability. You can buy 6 gallon aquatainers and fill them with tap water for an easy (and useful for camping) solution. Rotate every six months and you don't need secondary treatment.

Otherwise a food grade 55 gallon drum is $100 and you can fill it from your tap. You will want secondary treatment options if you plan to rotate just every 2 years, and you still need a smaller intermediary vessel.



Speak for yourself! I’m biking distance from a lake, so I’m going to focus on having enough bleach around. Bottled water is great… for bottles to do solar disinfection with. Though I guess I should really be worried about an algal bloom… ugh.

220gal IBCs should be $100 too, but maybe they’re more now.


you can buy handheld, portable, battery-powered, solar-recharging devices that electrolytically produce bleach from salt and water


Bleach degrades fast though. Look into pool shock and know how to make bleach from it.
