What is a borehole?
A borehole is a constructed hole in the ground from which groundwater can be abstracted. The hole is drilled by a drilling rig. The construction of the borehole is finished by installing a casing preventing collapse.
What is groundwater?
It is the water found in the subsurface in the saturated zone below the water table.
How do I find water?
There are various methods to determine the best possible drilling location, but the most often used are:
Scientific methods:
Geophysics (Magnetometer, Resistivity Meter, Aerial Photography)
Non-scientific methods:
(Water "dowsing" L-Rods, Y-Rods etc.)
