Which country has the maximum number of tube-wells in the world? Correct Answer India

A tube well consists of a wrought iron pipe armed which has a sharp point and a series of perforations at the lower end. It is responsible for bringing groundwater upwards. In UP, the first tube-well of India was dug in 1930. India holds the record of the maximum number of tube-wells (about 50 lac at present).

  • The rank of states is as follows: UP, Rajasthan, MP, Punjab, Gujarat, Maharastra and Bihar.
  • The three types of Tube wells working in India: Cavity Type, Strainer Type, Slotted Type.

 

Type of Pipe

Function

Cavity Type

A solid cavity is formed in which water is taken out from bottom rather than sides

Strainer Type

In this, the wire net is accommodated in the cavity to prevent soil particles.

Slotted Type

Unlike strainer, this tube well prevents soil particles with the mixture of gravel & coarse sand

 

Hence, we conclude from the above that India has the highest number of tube-wells.
