Hi,
It is good to see another Mainer on Permies :)
How deep would it need to be able to go? If you have a high water table and only need to go down 30ft or so... there are some very reasonable hand pumps.
https://www.lehmans.com/product/enclosed-top-cistern-pump/ for instance can go to 25' and is only a couple hundred. If you need to go deep, then Bison and Simple are probably the two top brands... and both can be expensive.
I'm not too worried about plastic. I'd rather not use it, and I'd rather not have food come in contact with it... but there are things I'm working on first that have greater impact.
Lastly, any chance of rainwater collection in a high place and gravity feeding it to where you want it?
