what water tube Wells what conditions are necessary for building tubewells
Answers
Tube well irrigation comes under lift irrigation. Tube well is a small diameter hole drilled in the subsoil formation. The cross-sectional area of this type of well is small and unless some mechanical power is used for lifting water, rate of water withdrawal will be low.
A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-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.
