Thinking of doing the same here. Glazed tile liner about 24" around, water at 14' down. Needs shocked, tested and a little block building over it. I wanna put a manual pump in/on it for emergency use. I have a few old belt drive pump units from the 1940's around, I might try to "rig" one of these to a bicycle to use to pump. There was a slaughterhouse on our property back in the early teens. This cistern/well supplied the slaughthouse via gravity and lead pipe (all gone now) but the cistern remains.
