2.2 Deep-Well Boring Since the Mid-Twentieth Century
The number of deep wells has increased drastically since the mid-twentieth century.
Introduction of the deep-depth drilling machine enabled the drilling of wells up to
one thousand metres, and the development of a groundwater probe made it easier to
search for groundwater. Moreover, the power pumps diffused the water supply more
than the method of drawing water using the animal power of camels and cows.
Thus, the development of technology after the mid-twentieth century enabled the
discharging of a large amount of water that could not have been imagined previously. However, the development of well-drilling technology has transitioned the
well-drilling actors from the local communities and farmers to the state and large
