You know I created this sub forum many years ago, thinking it was a great place to discuss hypothetical situations such as an entire capital city having no drinking water. Of course back then the whole thing was hypothetical, I didn’t think realistically that it could happen outside of a local scale.
I would say that this ranks higher than even a wide scale power black out in terms of SHTF levels of bad.
It’s really hard to overstate how much you need water for just routine living. We’ve always maintained a supply of drinking water and utility water, sufficient for about three days, longer if we use only “outdoor plumbing” so to speak.
I’m not really sure how I would maintain a reasonable supply of water if I didn’t have the benefit of storage space. I guess the message here is no matter where you live try to maintain a good source of your own water to drink.
