Just a thought, since we've discussed dehydrated vs canned foods/MREs in this thread:



We have old infrastructure in my neighbourhood, and our water main gets shut off at least twice a year for repairs. We haven't lost water yet due to an emergency, but it is something that we prepare for at our house. If we lived in an earthquake zone, I imagine that it would be a higher priority for us.

We store water at home, and at the moment our pantry consists mostly of canned goods, rather than dehydrated. I am very aware of this when I'm backpacking, but I have to keep water consumption in mind as we do more dehydrating for home, and also consider it when rationing our home stores in a possible emergency.
