What Is Borehole Drilling?
Borehole drilling is the process of drilling deep underground to access groundwater stored in aquifers.
A borehole uses drilling rigs to penetrate soil and rock layers until water-bearing zones are reached. Pipes called casings are then installed to protect the borehole from collapsing.
After drilling, pumps are installed to bring water to the surface.
