Borewells are vertically drilled wells to extract water from underground aquifers. The borewell pipes that are inserted to draw water out are known as column pipes. These column pipes play a major role in the functioning and life of the borewell.

Borewells can be categorized on various parameters. Two Major parameters are: method Used for borewell and Type of Borewell Pipe used. Method and Machinery Used can vary depending on geological factors and the purpose of borewell.

The types of Borewell are:

• Hard Borewell
• Slow Rig and Rotary Rig
• Power Rig

There are various drilling methods too like Water Jetting, Augur Drilling, Calyx Drilling, Percussion Drilling, Rotary Drilling, Down the Hole Hammering (DTH) Drilling, etc.
