Can't speak for anyone else, but here in Phoenix, if the municipal water stops pumping for whatever reason, options are very scarce, and hope you have a good multi-stage filter + UV setup with at least an OK source of water. You should generally have 15 gallons of clean drinking water per person on hand, which should last a couple weeks. In addition to a larger supply of water for washing/flushing. TBH, I don't have this much, have about 15 gallons of fresh drinking water for 2 people, and a pool in the back with enough chemicals to keep it treated for a few months (flushing/cleaning use)... I could probably rig something with my RO and a UV light with a tank pump and a few other bits if it really came down to it though. Have thought it might be cool to build a trailer with a generator, portable filtration system and water tank... The reality is, if things went bad, generally would only be for a couple weeks where I am, or would be bad enough that migration to another area would be necessary and at that point, who knows.
