Tube well irrigation has the following advantages excepta)ubewells can...
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.
Advantages of Tube well irrigation
Advantages of Tube well irrigation
- Tube well can be constructed quickly
- The quality of water is good
- Land acquisition is less as compared to canal
- Tube well can be privately owned but canal is not privately owned
- Tube well water is much costller to canal water
- Tube well require less space
- Tube well give fairly sustained yield even in dry years.
Classification of tube wells:
(a) Strainer type tube well:
The strainer type tube well is generally unsuitable for very fine sandy strata, because in that case the size of mesh opening will have to be reduced considerably which may result in choking of the strainer, and if the screen openings are kept bigger, the well will start discharging sandy water.
(b) Cavity type tube well
If a suitable strong clay stratum is not available then cavity type tube well cannot be provided because it does not have strainers and hence, it draws its supplies from the bottom and not from the sides.
(c) Slotted type tube well
In this type of tube well, the gravel and coarse sand shrouding prevents the fine particles from entering the well pipe. If sufficient depth of water bearing stratum is not available, then it is not possible to provide strainer or cavity type tube wells, hence, slotted type tube wells provided in that case.

Important Points
Although the maximum discharge of a deep tube well exceeds 200 liters/sec but can never reach 500 liters/second.
Discharge through tube well is much more than 5 liters/second and thus the most appropriate answer is 50 liters/second.
Note: The discharge of an open well is limited to 3 to 6 liters/second.

Advantages of Tube Well Irrigation
Tube well irrigation is a popular method of obtaining water for irrigation purposes. It involves the drilling of a borehole into the ground and installing a tube well to extract groundwater. This method has several advantages, which are listed below:
a) Privately Owned: One of the advantages of tube well irrigation is that tube wells can be privately owned. This means that individual farmers or landowners can install and maintain their own tube wells, giving them exclusive access to the groundwater resources on their land. This ownership provides them with control over the water supply, allowing them to manage it according to their needs.
b) Faster Construction and Lower Cost: Tube well construction is faster compared to other irrigation methods such as canal irrigation. The process involves drilling a borehole and installing the necessary equipment, which can be completed relatively quickly. Additionally, tube well construction requires fewer funds compared to large-scale canal projects, making it a more economically viable option for individual farmers or small communities.
c) Less Land Acquisition: Unlike canal irrigation, which often requires the acquisition of large tracts of land for the construction of canals and reservoirs, tube well irrigation requires less land. Only a small area is needed for the installation of the tube well itself. This reduces the need for land acquisition, making it a more feasible option in areas where land availability is limited or expensive.
d) Cheaper Water Supply: Tube well water is generally cheaper compared to canal water. This is because canal water often involves additional costs such as maintenance, operation, and distribution expenses. Tube well water, on the other hand, is directly pumped from underground sources, requiring less infrastructure and maintenance. As a result, farmers using tube well irrigation can benefit from a cost-effective water supply.
In summary, tube well irrigation offers several advantages, including private ownership, faster construction, lower cost, and reduced land acquisition. However, it does not provide the advantage of cheaper water supply, as tube well water is generally more affordable compared to canal water.
