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.
Assuming you have sunny days could you leave the (river? rain?) water all day in clear containers for the UV? You might need to do a lot at once to save for non sunny days.
Assuming no industrial pollution.
Probably want some resorts before
this last resort though.
