Water Use Reality Check

I've read we can go weeks without food but not very many days without water. With that being said, water should be the number one priority for preparedness and survival during hard economic times. Adequate preparedness requires studying what is available in YOUR immediate area. If what YOU need isn't available within a reasonable distance, you might want to consider moving. This is something I am currently pondering given that I live in the desert and our water supply can be very limited in the event of a disaster.
A recent news story revealed that a local city wastewater treatment employee, angered that he didn't get a raise among other issues, was attempting to blow up a quarter city block along with the water treatment plant. The explosion wouldn't have reached my neighborhood but it would have surely affected our water supply.
