Not off grid but we don't have running water. We bring bottles and blue jugs from home and I am lucky that there is 3 small lakes within walking distance to get water for showers and what not, we just reuse old water jugs from the grocery. I also had a "water wagon" built with a 50l sprayer type barrel and a diaphragm pump that I was going to use to fill up at the lake and bring it back to fill one of those 1000l water containers but we don't use enough water to need it. I'm lucky enough in my area that I can have bulk water delivered, so that is an option for filling the 1000l each spring if I ever need to. My neighbor had a sandpoint put in maybe 10 years ago, said it cost him 6k, he seems to be happy with it.
