After using a "Hydra-Drill" to bore down to 75', I got the bits stuck and then retrieved after collapses "even with bentonite". I was able to sink 3" PVC casing down to the 60' level with the last 10' being slotted PVC as a screen. Now I need a pump. The casing I.D. is 3" and I suspect the pump will need to lift at most 60' and product 5 or less GPM. I'm only going to run the water into a nearby shallow pond so was looking at a solar system. Has anyone got any suggestions? I really like the simplicity of the Aermoter "check-valve" type windmill pumps but figure I have more sun than wind. Does anyone make a linear-acting electric pump or are they all rotary/centrifugal devices? Fred in Michigan.
