How Are Borewells Drilled?
Water borewells are one of the most common sources of water. They are professionally dug wells that penetrate deep into the ground to tap water from water bearing soil and rocks.
Drilling of borewells is not an easy process. Many factors need to be considered before drilling borewells.
- Topography Of The Land
Before drilling a borewell, the topography and contour of the land needs to be considered. The topography of the land can be determined by professional hydro geologists who can also locate the position of water below the ground. Hydro geologists chalk out the eventual path for the drilling work to be carried out, making certain that the drilling process does not affect any other underground laid pipes or connections. Al Abrag Est, one of the leading drilling companies in Doha employ professional hydro geologists for all drilling works.
- Drilling The Borewell
The next step is drilling the borewell into the ground and up to the level of groundwater. The steps to drilling the borewell must follow a scientific approach to get the best results. A small error in determining the drilling of the borewell can lead to catastrophic losses.
- Water Yield
The purpose of drilling a borewell is to obtain maximum ground water from the site. Assessing the yield of water can be determined by using test pumps and certain calculations. Determining the yield of water is difficult due to the shift in variables. Proper examination of borewell sites along with the right measures can give a 90% accuracy with regard to the yield of the borehole.
- Installation
Drilling of borewells in the desired sites needs to comply with the local regulations regarding drilling of borewells. Once all the compliances are met, installing borewell pumps and pipes is the next stage. The type of pump set and size of pipes among other criteria, depends on the purpose the borewell is going to be used for.
Cost Of Drilling Borewells
The cost of drilling borewell largely depends on a number of influencing factors
Topography Of Land
The topography of land largely affects the cost of the borewell to be drilled. This is because groundwater will flow differently depending on the type of soil or rock. Having an experienced hydro geologist on the team will ensure accurate estimation of costs.
Depth Of Borehole To Be Drilled
The deeper the borewell the higher the costs of drilling. At locations where groundwater is deep, more machinery and equipment may be required to drill.
Purpose Of The Borewell
As mentioned earlier, the purpose of the borewell is an important factor that determines the type of installation and the type of pump sets and pipes used. Borewells used for domestic purposes may use lighter powered pumps when compared to pump sets and pipes used for industrial purposes.
Manpower
The cost of drilling borewells is directly proportionate to the labour, machinery and materials used in construction.
Drilling boreholes is not a simple task. It requires the expertise of professionals as well as the work of skilled and manual labour. A well experienced drilling company in Qatar like Al Abrag Est can offer professional services when it comes to the drilling of borewells.
