Waterwell drilling is essentially drilling for underground water for agricultural and residential water needs. A perfect waterwell drilling setup would include: - A drill rig system which includes DTH hammer, DTH bit and drill tubes - Reliable skid mounted diesel air compressor. When drilling a water well through the hard rock, no drilling method is as efficient as a DTH Hammer energized by the right air compressor providing high enough pressure. Softer grounds may also be drilled by air flushed rotary drilling, demanding a lower pressure air.. Air pressure requirement: The air compressor must provide sufficient air pressure to overcome the formation resistance encountered by the drill bit and maintain the drilling force. Typical air compressor pressures range from 7-30 bar (100-450 psi). [pdf]
