Hope you have a good amount of water stashed somewhere. We can do ok without electricity here, but water doesn’t get out of the well without the pump, so we keep a stash.
One of the first things I do is to drain the pipes into containers for water to drink before someone forgets and flushes the toilet.
We do have a stash, too, potable, grey, and distilled.
Also, I can directly tap the cistern tanks, if need be.
