I had thought about a system

I had thought about a system such as yours. It seemed good. My only problem with it is how long will it take to find out if the local water supply has been "compromised". There have been several plots uncovered, that used bio, chem, and nuke to attack the supply to several major metropolitan areas. I'll stick with the barrels. They can be kept for 5 years. I just rotate them. I got tired of labeling, storing and rotating plastic jugs.
