What is borewell and its types? – A borewell is a type of well that is drilled into the ground to access groundwater for various purposes such as drinking, irrigation, and industrial use. Borewells are typically constructed by drilling a narrow hole into the ground using a drilling rig or equipment.

Types of Borewell

There are different types of borewells based on their construction and the type of soil or rock they penetrate. Here are some common types of borewells:

Dug well or open well borewell:

A dug well or open well borewell is a type of borewell that is constructed by excavating a hole in the ground until the water table is reached. This type of borewell is commonly found in rural areas and is lined with brick, stone, or concrete rings to prevent collapse and contamination.

Dug well borewells are suitable for areas with shallow water tables and are commonly used for domestic purposes such as drinking, cooking, and bathing. However, they are prone to contamination from surface runoff and sewage, and regular maintenance is required to ensure the safety of the water.

Driven borewell

A driven borewell is a type of borewell that is constructed by driving a casing pipe into the ground using a heavy hammer or a pile driver. This type of borewell is commonly used in areas where the soil is soft and the water table is shallow.

Driven borewells are suitable for areas with soft soil and shallow water tables. They are relatively easy to construct and are less expensive than other types of borewells. However, they are prone to collapse and are not suitable for areas with hard soil or rock formations. Regular maintenance is required to prevent contamination and ensure the safety of the water.

Tube well borewell

A tube well borewell is a type of borewell that is constructed by driving a series of PVC or steel pipes into the ground until they reach the water table. This type of borewell is commonly used in areas with hard soil or rock formations and where the water table is deep.

Tube well borewells are suitable for areas with hard soil or rock formations and where the water table is deep. They are less prone to collapse and are more durable than other types of borewells. However, they are more expensive to construct and require specialized equipment and expertise. Regular maintenance is required to prevent contamination and ensure the safety of the water.

Auger borewell

An auger borewell is a type of borewell that is constructed using a drilling rig equipped with an auger bit. The auger bit is a large helical drill that is used to bore through the soil and rock to reach the water table. This type of borewell is commonly used in areas with soft soil and where the water table is relatively shallow.

Auger borewells are suitable for areas with soft soil and where the water table is relatively shallow. They are less expensive than other types of borewells and require less specialized equipment and expertise. However, they are prone to collapse and are not suitable for areas with hard soil or rock formations. Regular maintenance is required to prevent contamination and ensure the safety of the water.

Rotary borewell

A rotary borewell is a type of borewell that is constructed using a drilling rig equipped with a rotary bit. The rotary bit is a cutting tool that is attached to the end of a drill stem and is used to bore through the soil and rock to reach the water table. This type of borewell is commonly used in areas with hard soil or rock formations and where the water table is deep.

Rotary borewells are suitable for areas with hard soil or rock formations and where the water table is deep. They are more expensive than other types of borewells and require specialized equipment and expertise. However, they are more durable and less prone to collapse than other types of borewells. Regular maintenance is required to prevent contamination and ensure the safety of the water.

Conclusion –

The type of borewell that is best suited for a particular location depends on various factors such as soil type, water table depth, and the intended use of the borewell. It is important to consult with a qualified professional before constructing a borewell to ensure that it is safe and reliable.
