Common Misconception....

Theoritically the "Yield" of an well is entirely dependent on the underlaying soil properties. Historically dug wells were being used by small communities with relatively small water demands and usually use to tap in the higher aquifers.

Whereas with the advent of technology boring (using mechanical means) have rapidly became cheaper and affordable allowing users (local bodies/governments/ communities) to dig deeper into the earth and thus tap deeper and more than one aquifers. Tube wells are generally used to tap underground water to cater for higher water demand. Thus there is a common understanding that TWs yield more than the dug wells.

It is the water demand that dictates the use of technology.
