The point is that people don’t want to constantly be collecting and storing water for a power outage. They want to be able to take regular showers. And really, in CT, as significant as the question of water is the question of heat.
I can only look at it from the viewpoint of a country-raised Texan in a rural area-but if you want total convenience all the time, you buy a generator, as some of the posters suggested, or live in a city or town of good size. CT just doesn’t sound like the kind of “rural living” I’m used to. It sounds more like a city person’s idea of “roughing it”.
I didn’t see heat mentioned, but in an area of snowy winters, that is a real concern. Winter is mild here compared to CT, but everyone I know has at least one woodstove or fireplace, and buys a cord of firewood each Fall or gets permission to cut storm downed-or-dead trees on someone’s ranch.
There was no furnace in our ranch house, but there were a couple of fireplaces and a woodstove, and a space heater in the bathroom.
I’ll be building my next home to be off-grid-with solar power, and all of that stuff-not something I imagine would go over well in CT.
