If there is a pond nearby, you can use the water from it with a small pump and generator, which is what I did on my land. But why do you need a well if you have a pond, you ask? The pond was built by a nincompoop and it leaks so I was trying to keep the catfish in it from dying. It is a losing battle when it is over 100 degrees everyday.
I do have a stream on my land. It’s fairly close to the source, but it also runs through 3 farms and a dozen smaller properties. In a crunch it could be purified enough for drinking using one of those “drink your own ditchwater” filter/purifiers, but I’m not so sure about pumping it into what would become my new well. I need to do more research on that.
On the other hand, it would be a great stream for hydropower!
