Question

Which of the following is used maximum for lifting water from wells?
A. Persian wheel ( Rahat )
B. Swing basket ( Bedi )
C. Dhikuli
D. Doon

Answer 1

Hint: Well is a structure created in the ground by digging, drilling, or driving to access groundwater in underground aquifers, or a pocket of water trapped between layers of permeable rock. For thousands of years, societies all over the world have found different ways to access water.

Complete Answer:
Let us analyse the options for finding the correct answer.
Option A : Persian Wheel ( Rahat )
The Rahat system of irrigation is a way to get water from a well in which large wheels are used. It is tied to oxen and is turned by them to get water out of the wells.
As many wheels are used in this system so it can lift up much water into the field. (Correct answer)

Option B: Swing basket also known as dekli or bedi is a manual method by which water is taken from the well directly using a pulley. The farmers use a basket from the well and pour it into the pipes which leads into the fields. Therefore, this is the incorrect answer.

Option C : Dhikuli
In this device a vertical pole is employed for balancing the bucket and the equivalent load fixed on either ends. (Incorrect answer)

Option D: Doon
Similar to the swing basket method, even the doon method is meant for lifting small water for a small height. It is basically a wooden channel which is closed at one end and open at the other. Only a small amount of water can be lifted using this method. Therefore, this is the incorrect option.

Thus, the correct option is A) Persian wheel (Rahat).

Note: Wells have traditionally been sunk by hand digging, as is the case in rural areas of the developing world. These wells are inexpensive and low-tech as they use mostly manual labour, and the structure can be lined with brick or stone as the excavation proceeds. A more modern method called caissoning uses precast reinforced concrete well rings that are lowered into the hole.
