Design Specifications

The SHIPO drill is based on the Baptist Drilling method developed by Terry Waller of Water for All in Bolivia in 1993. The drilling process is continuous and the drill bit is normally not removed from the borehole until it is finished. Any broken material is pumped to the surface in the drilling liquid (mud). The borehole diameter is kept as small as possible in order to remove a minimum of material. Percussion action is performed by lifting the drill stem with a rope over a pulley, attached to a simple derrick, made with whatever available that is usually either wood or bamboo poles. The main drill tool consists of a length of metal pipe with an open drill bit combined with sludging. Extensions are standard PVC potable water pipes. No temporary casing is used. Drilling speed is variable with different soil conditions and crews, but over 15 m per day have been obtained in favorable conditions. Specifications: Casing diameter range is 2 to 6 inches Equipment length: 3 m Estimated weight of Rota sludge: < 200 kg SHIPO method (Baptist drill) is estimated to have max weight: 100 kg
