Water Borehole Drilling involves drilling and casing a hole to access groundwater. There are two broad classes of water borehole drilling. The first is shallow or unconfined wells completed within the uppermost saturated aquifer at that location. The second is deep or confined wells, sunk through an impermeable stratum into an aquifer beneath.
Water Borehole drilling is often used in mine application to provide water feed for a processing plant (mill) i.e. water bore field. Water Borehole drilling can also be used in the application of construction dewatering.
On a construction or mine site, this dewatering may be implemented before subsurface excavation for foundations or mining to lower the water table. This frequently involves the use of a submersible “dewatering” pump.
