The ‘Well Machine’
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.
All the water wells that JEN is presently digging in Southern Sudan are 80m to 100m deep. 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.
However, at this stage, the water is undrinkable. The machine must continue to crush further through layers of rock and clay until it reaches depths of more than 100m underground and finally arrives at water that is clean enough for use.
