Your Choice for Expert Test Drilling at Angamaly, Ernakulam - A2Z Borewells & Electricals

We understand how difficult it can be for communities to access safe drinking water. That’s why many people turn to borewells as a solution. These wells are dug deep into the ground to extract water from aquifers, which are layers of soil or rock that hold water. Typically, the water is drawn from confined, deep aquifers located underground. The pressure between the cracks in these layers traps the water. Borewells are highly recommended because they can provide a reliable source of safe drinking water for those in need.

Conducting the Site Survey

The first step we initiate to do for very one of our projects is the site visit.  Before drilling a borewell, it is essential to conduct a thorough site survey to understand various details to make the project a success. This involves taking into account factors like the geological composition of the area, groundwater availability, other environmental factors, accessibility of machinery to the spot, dimensions of borewell – 5 inches (Normal domestic use), 6 inches (High domestic use) or 7 inches (Commercial, Industrial and Agriculture purpose) etc.

Mark the Spot

Once the site survey is complete, it is time to mark the spot where the borewell is to be drilled. Our expert professional surveyor does this with the help of the latest technology as well as the traditional method.  

Dig the Hole

The next step is to dig the hole for the borewell in the selected spot. This step is done using the most modern technology available, which forces into the earth’s surface with the power produced from the high-pressure compressor to blast the hole from the surface of the earth until the hard rock formation is hit.

Install the Casing

The casing is the lining of the borewell. It is important to ensure the casing is installed properly so the borewell can function properly. The casing pipes made of MS iron or PVC of the required grade and thickness diameter have been installed into the borehole, which works as a wall for the borehole, preventing the soil from falling into the well, and the drilling process continues till the water channels are found. We use the best products available in the market for the project as we are highly cautious of the quality of the products and services we offer.

Installation of the Pump

After the casing has been installed, the next step is to install the pump. This is done by attaching the pump to the casing and connecting it to the power source. We supply the best motor brands available in the market along with the other related electrical products you need.

Test the Borewell

Once the pump has been installed, it is time to test the borewell. This involves running the pump to ensure that it works properly and the water flows properly.

Monitoring Water Levels

Once the borewell is operational, it is important to monitor the water levels. This can be done using a water level meter. It is important to ensure that the water levels remain consistent.

Cleaning the Borewell

Keeping the borewell clean is important to prevent contamination. We complete this process using the high-tech machines available to us.

Disinfection of the Borewell

In order to prevent any bacteria or other contaminants from entering the borewell, it is important to disinfect it. This is done using chemicals or other disinfecting agents available widely.

Monitoring the Borewell

After the borewell is installed and is operational, it is important to monitor it regularly. This can be done by checking the water levels, ensuring the pump is working properly, and inspecting the borewell for any signs of damage.

Even though we are an acting borewell contractor, we do offer all custom services related to borewells like maintenance, well drilling, re boring etc.

The major factors to keep in mind when thinking of drilling a borewell

  1. The borewell should be cleaned at least once every two years to avoid blockage of sources.
  2. The depth of the borewell completely depends on the depth where adequate water channels are found, and even though the possibility of finding water is higher, sometimes the water may not be available or edible depending on the geographic structure of the land.
  3. The borewell water is recommended to use after filtration for the best of its form.
  4. The borewell can be bored down even after finding the water channel if it is found insufficient for the use, but cannot be bored down if the water channel is powerful enough.
  5. The minimum depth recommended for the borewell is 100 Feet.

7 Significant borewell drilling methods in Ernakulam

There are several significant borewell drilling methods used in various scenarios:
1. Cable Tool Drilling: This method involves raising and dropping a heavy chisel bit attached to a cable to break the rock, soil, or strata. It is a slow and labour-intensive drilling technique primarily used for shallow wells.
2. Percussion Drilling: The drill bit is attached to a drill string, which is repeatedly raised and dropped to create a hole. The impact of the bit breaks the rock or soil, and the loose material is cleared using water or air. It is commonly used for deeper wells.
3. Rotary Drilling: This drilling technique involves a rotating drill bit attached to the end of a drill string. The drill bit grinds away the rock or soil, and the drilling fluid (usually a mixture of water and drilling mud) helps remove the debris and cool the bit. Rotary drilling is commonly used for both shallow and deep wells.
4. DTH (Down-the-Hole) Drilling: This method involves a pneumatic or hydraulic hammer attached to the end of the drill string. The hammer rapidly strikes the drill bit, creating fractures in the rock or soil, and the debris is flushed out by high-pressure air or water. DTH drilling is commonly used for deep borewells in hard rock formations.
5. Auger Drilling: Auger drilling utilizes a rotating helical screw blade, known as an auger, to excavate the material. The cuttings are carried to the surface by the auger, and this method is typically used for drilling in softer soils or clayey formations.
6. Jetting Drilling: This technique involves the use of high-pressure water or air jets to erode and remove the soil or rock particles. It is particularly useful in drilling through loose or unconsolidated formations.
7. Sonic Drilling: Sonic drilling uses high-frequency vibrations generated by a resonant drill head to create a hole. The vibrations liquefy the soil or fracture the rock, allowing for easier removal. This method is commonly used for various geological applications like environmental drilling and mineral exploration.
It’s important to note that the suitability of each drilling method depends on the specific site conditions, rock formations, depth requirements, and various other factors. 

The cost of a borewell is calculated based on various factors, including the following:
1. Depth: The total depth required for the borewell is a primary factor in determining the cost. Deeper borewells involve more drilling and excavation, leading to increased costs.
2. Diameter: The diameter of the borewell also affects the cost. Larger diameter borewells require more materials and time for drilling, making them more expensive.
3. Geographical location: The location of the borewell plays a role in the cost calculation. Access to the site, soil conditions, and water availability affect the drilling process and overall cost.
4. Type of equipment: The type of drilling equipment used impacts the cost. Different equipment has varying capabilities, efficiency, and cost factors associated with them.
5. Additional services: Additional services such as casing, installation of a pump, testing, or water treatment may be required, adding to the overall cost.
6. Labor and transportation: The cost of labour and transportation of materials and equipment to the site are also considered in the total cost.
It is essential to consult with drilling contractors or professionals who specialize in borewell installation services to get an accurate cost estimate based on these factors.

1 inch of water in a Borewell can be calculated by converting the unit of measurement. 
1 inch = 0.0254 meters
To find the volume of water in a Borewell, the formula V = πr²h is used, where V is the volume, π is the mathematical constant pi, r is the radius, and h is the height of the water.
Assuming the Borewell has a radius of 0.5 meters (to show an example), the calculation would be:
V = π(0.5)²(0.0254)
V = 0.003927 m³
Therefore, 1 inch of water in a Borewell would be approximately 0.003927 cubic meters.
