Air lift pumps are definitely a neat idea for filling tanks or aerating ponds. For a wind setup, besides the air pump you will need a compressor, set of blades and a tower. I think most agricultural setups are nearing $2,000 all in. It might not work in the woods or at least you would need a really tall tower to get above the trees. Of course, if you have a wind turbine or solar electric system already, you could always use a DC powered electric compressor and skip the wind tower all together, but then, there are plenty of inexpensive submersible DC well pumps too. If your wells aren’t too deep, a direct solar pump (DC pump and small PV array) is often used for filling stock tanks, where there is no electricity, while the sun is shining.
