The ‘Well Machine’

20071106_sudan_jpf_lainya_borehole_ Hello everyone!

JEN has been digging water wells throughout our project sites around the world, but one aspect of this that has not received widespread attention is the ‘well machine’ that installs these wells. I would like to take this opportunity to explain how this machine works.

In order to dig to such depths, the machine often comes across extremely dense layers of rocks and clay. The machine crushes through the layers of rock and clay, and like a rocket taking off, lifts massive amounts of sand up into the air. Water then floods into the dried layers of clay.
