The diameter of the borewell ranges from 4.5 to 6 inches. Individual houses prefer 4.5 inches, while 6-inch borewell yields higher to cater the requirements of the large apartment buildings or agricultural purposes.

How does borewell work?
Borewells are primarily vertically drilled wells which are bored into the aquifer in the earth surface to extract water. The casing pipe is the support to the external surface of the borehole. This casing helps to avoid the damages that may occur at specific depths. Continued by this, electrical pumps are used to pump out the borewell water from the borehole.
The PVC made casing pipes are the best borewell pipes which more predominant in the market than the other types. Earlier, GI/Mild steel casing pipes were in use and corrosion made it unsuitable for this purpose. Use the standard unplasticized PVC pipe that abides with the BIS specification IS 12818: 1992. Slotted PVC casing pipes are in use when dealing with the sandy or boulder surfaces and also to prevent the entry of sands along with the borewell water flow.
How to choose the right pump for your borewell?
We can categorize pumps into two categories depending on the purpose of the usage. One is for domestic use while the other is for agricultural purposes. Here is a list of both category pumps with their characteristics.
Jet pumps: These pumps are suitable for pumping out clear water free from abrasive and chemically aggressive substances. It fits perfectly for borewell depths up to 150 feet.
Compressor pumps: Preferred for low yielding borewells. It is easy to install and maintain. The problem is that these pumps are noisy and needs regular repairs.
Submersible pumps: This efficient pump holds a sealed motor entirely submerged into the bore wells. They provide higher discharge as well as higher performance. These pumps are prone to repairs when the borewell consists of heavy slit particles.
It is essential to consider the depth at which the pump is to be installed and the expected discharge while deciding on the capacity of the pump. The depth at which the pump can be installed is decided by the depth of the entire borewell. The pump depth is mostly maintained 10-25 feet above the total depth of pumps.
