Tube well
A tube well is a type of water well in which a long 100–200 millimetres (3.9–7.9in) wide stainless steel tube or pipe is bored into an underground aquifer. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.
