Edited the post for clarification. It's $5K+ for the well, then the operating costs on top of that. I haven't figured out the plumbing that would be needed for it either. It has to be freeze proof if it turns off in the winter for any length of time.
JKB, you'd better get crackin' on that running 3 phase on single phase stuff for your property. I'll need that info this yaer!
