Water requirements...for the long term

Did you ever stop to think about how much water we actually use?
I just finished canning peaches, and thinking that in a SHTF situation, where water may be at a premium, canning takes way too much water to make it a viable way to store food. During the growing months, we may have all we can do to get enough water for growing food (and for our own drinking, cooking, sanitation). Perhaps a solar dehydrator would be a better alternative for food storage.
Do you think canning is a good choice?
I guess it would depend a lot on the water supply and how hard it would be to get it and/or make it potable. If we have a shallow well and a hand pump, it might not be too much of a factor, except for getting it from the well to the cooking area. But almost any other source of water would need to be filtered/sterilized before it could/should be used for canning.

I am assuming that electricity would be out also, so that a deep well pump would only work as long as there was enough fuel for a generator.
Rain water can be used for non consumption purposes, but still the amount needed would probably exceed water storage containers, especially if we had a dry summer.

It has been said that each person needs a gallon a day for drinking, and another gallon or two for hygiene. But I think I must have used at least 20 gallons not counting washing of the jars and then the pots afterward...all for 14 pints of peaches. If I were canning every day for a month or so, it would get old real fast, IF I could get that much water in a potable state consistently.

Probably we have all thought about the day to day water needs in a SHTF, but what about the amount needed for food production, food preservation, washing dishes and pots and pans (can't use paper plates forever) or for laundry. A child in diapers would need a lot of water just to keep the kid clean, and then to wash the diapers.
What about when someone is sick, and/or incontinent. Just trying to keep clean linens so they are comfortable and sanitary would be overwhelming...it's overwheling enough when we just turn on the spigot.

Yikes, I think I need to re-think my water situation.
Has anyone in this group looked into some way to pump from a deep well without electricity?
Other than mutant zombies (think bang-bang) water seems to be the biggest challenge.
