Hire top borewell contractors with best price in Margao
Borewell contractors are the ones who help you in all the aspects related to borewells like identifying the drill point, borewell drilling, or in choosing the right method. Borewell contractors in Margao are growing fast to provide the best services for its customers.
What are the phases of borewell installation process?
Phase 1: Identification of the drill point
It is the primary step that is taken to identify the right place where the possibility of getting water is high. Vertical electrical sounding is one of the standard methods practiced for finding the drill point that is suitable for domestic purposes. It requires a wide open area to conduct the survey and cost about Rs.1500-5000. Some other methods like geophysical surveys, diviner wooden sticks or magnetic blocks also help in finding the spot. It is necessary to spot the right place to drill, which when failed results in loss of money.
Phase 2: Selection of borewell sites and drilling season
In summer, identifying the drill point or borewell drilling the borewell may end up in bad results in areas of Margao. However, it entirely depends on the groundwater potential of that particular site.
Some experts consider summer as a good season for bore well, and agricultural lands get access to drilling rigs only in summers. It is better to discuss with the local borewell contractor who holds knowledge about the local area.
Phase 3: Adoption of the suitable borewell drilling method
You need to consider the geological formation under the land which may be alluvial, boulder or hard rock. Other factors like expense, diameter, depth and the purpose of the borewell play a significant role in the selection of the borewell drilling method. Some of the effective drilling methods popular in Margao are listed below.
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.
Market rates of borewell implementation in Margao
The calculation of the drilling charges can be of many types depending on the method and purpose of the drilling. Here is the breakdown of the charges that a borewell contractor may charge you.
- Borewell drilling cost per feet
- Casing pipe cost per feet
- Drilling cost + charge for installation of the casing pipe per feet
- Flushing charges per hour. (After drilling)
- Transportation charges
The approximate borewell drilling cost estimate would be around 1-1.5 lakhs. It would borewell cost per feet about Rs. 300-500 depending on the diameter of the pipe.
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.
