  • Yes it works in rocky soil, the best thing is to ask around and look for existing wells.

  • A clay that seals leaky soil, it was not necessary in this instance.

  • Terry Waller, of San Angelo TX, developed the drilling technique over the last 20 plus years and it has been copied by many groups and individuals around the world. you can see the wiki page on Baptist well drilling.

  • It's nice that there are Gringos who can come up with cool ideas like this.

  • Speaking as an engineer, this is some of the most sensible, practical and, in purely engineering design terms, some of the highest quality and most efficient engineering I have ever seen. Congratulations.

  • yes bentonite is sometime used to help seal loose soils. Bentonite is a comercial drilling clay.

  • Nice technique. How can I learn more details so I can teach this in Cambodia?
