Boreholes are resistant to many forms of natural and man made disasters. Although the components above ground may be damaged, the narrow opening at the top of the borehole often prevents contamination of the water supply or damage to the pump components below ground. The main exception to this is damage caused by earthquakes, which can be greater below ground than the damage seen on the surface.
