Ray is speaking of a device called a well point. These have hardened tips and a screen on the lowest section. These are commercially available. I have never installed a well point as they are illegal here and because we have too much pee gravel here in the mountains. Unlike other pee gravel elsewhere, our pee gravel is so large you can stand behind it and pee, and your neighbors cant see you. These should work good in areas with no rocks and shallow water.
