Been there done that. At the beginning of July our town was shutdown by a storm for almost a week.
No electricity, Water was unusable (the Water Works couldn't run properly due to the power outage.)No gas stations worked. Stores were closed. We managed fine with our stores of food and water and used my "water still" to get us drinkable water and we had enough stored water to wash with. We didn't activate our rain storage system but we were getting close.
What state are you in?
I tried going without electricity and it sucks. The AC doesn’t work. Satellite TV? fuhgettaboutit. However,like you, I have my back-up “water still” and can make creek water into potable water if needed. It makes the hobby more palatable to the missus.
