Very cool stuff Orin! Less than 2 weeks now till I'm up there and can start looking for a spot to put my deep roots stake in, current plan is to retire in March next year, sell the house, pack up what remains and drive over to start building. I pieced together a 24v system here with used batteries to cut my teeth on, so if I made a mistake it wasn't ruining expensive batteries. I'd definitely suggest a page of instructions for using the cistern, similar to what is in the willow feeders if that's an option.
Do you know if any work was done yet on the well house for the new deep well, or if a well pump was ordered for that? Do you have any plans for winter use of your tank, or will it be emptied to winterize it? I had thought about integrating a cistern into my earth berm, with the water inlet/outlet accessible from within the structure. If it's just a foot or two above the sink faucet and you use a 1" line with no restrictions, you get a decent flow especially when full.
I'm not quite a lumberjack, but that's OK, I sleep all night and I dream all day; I'll coppice trees, I'll grow my food, and compost poo and pee! With a well and off-grid solar, it's a permies life for me! https://www.youtube.com/watch?v=FshU58nI0Ts
