Why? Well drilling is hardly high-tech: it's well over 100 years old. You should be able to pick up an old cable-drilling rig in Texas for scrap price. For that matter, you could drive a well to 12 meters. There also some interesting "low tech" approaches. Google "drilled well" OR "tubewell". -- John Hasler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
