If I HAVE to go backwards, I still want running water in the house.
A flush toilet is optional. Ever hear of Humanure? It’s all the rage these days.
UGH!
Unless you have an Artesian Well, my aunt in Mississippi had one, running water in the house without electricity is kinda difficult.
Of course you could build a cistern on stilts and collect rainwater, to get the differential flow, but in winter it would be frozen solid..............
