Borewell vs Tube well – Know Genuine Difference

Borewells and tube wells are both vertical drilled wells that are used to extract water from underground aquifers. However, there are some key differences between the two.

Casing

The main difference between borewells and tube wells is the type of casing used. The casing is a pipe that is inserted into the borehole to prevent the sides from collapsing. In borewells, the casing is only inserted up to the soil-rock boundary. This is because borewells are typically drilled in hard rock, which is less likely to collapse. In tube wells, the casing is inserted all the way to the bottom of the borehole. This is because tube wells are typically drilled in soft soil, which is more likely to collapse.

Depth

Borewells are typically drilled to a shallower depth than tube wells. This is because borewells are only needed to reach the water table in hard rock. Tube wells, on the other hand, may need to be drilled to a much deeper depth to reach the water table in soft soil.

Pumping

Borewells and tube wells can be used with a variety of pumps. However, deep tube wells typically require a submersible pump, which is a pump that is lowered into the well and submerged in the water. Borewells, on the other hand, can be used with a variety of pumps, including submersible pumps, surface pumps, and hand pumps.

Cost

Borewells are typically less expensive to drill than tube wells. This is because borewells can be drilled in shallower depths and do not require as much casing. However, the cost of pumping water from a borewell may be higher than the cost of pumping water from a tube well.

Advantages and disadvantages

The advantages of borewells include:

• They are less expensive to drill than tube wells.
• They can be drilled in shallower depths.
• They can be used with a variety of pumps.

The disadvantages of borewells include:

• They may not be able to reach the water table in soft soil.
• They may not be able to provide a large enough water supply for large households or businesses.

The advantages of tube wells include:

• They can reach the water table in soft soil.
• They can provide a large enough water supply for large households or businesses.

The disadvantages of tube wells include:

• They are more expensive to drill than borewells.
• They require more casing.
• They may require a submersible pump, which can be more expensive than other types of pumps.

Which type is right for you?

The type of well that is right for you will depend on your specific needs and circumstances. If you need a well that is relatively inexpensive to drill and can be used with a variety of pumps, then a borewell may be a good option for you and Al Abragest can help you. If you need a well that can reach the water table in soft soil and provide a large enough water supply for a large household or business, then a tube well may be a better option.

Ultimately, the best way to determine which type of well is right for you is to consult with a qualified well drilling contractor like our team at Al Abrag. We will be able to assess your needs and recommend the best type of well for your situation.

How to Drill a Borewell: Step-by-Step Guide by Al Abrag

Drilling and boring techniques have evolved today such that drilling and completing a borewell today take only 4 to 5 days. However, the planning behind these borewells takes place for a much longer period of time. In order to streamline this process for you, Al Abrag brings you the most comprehensive yet compact step-by-step guide to drilling borewells. 

1. Identifying the Borewell Point

This is the first step in drilling a borewell. Not all locations in Qatar have sufficient groundwater reservoirs. Hence, identifying the right point where a borewell shaft can penetrate an underground aquifer is a key step to drilling a fully functional borewell.  There are two types of methods that are used in doing this – the scientific method and the pseudoscientific method. 

• Scientific Methods

These scientifically proven methods are often the most accurate. However, due to several procedures being involved, they may be more time-consuming than pseudoscientific methods. Some of the scientific techniques of borewell drilling point identification include Vertical electrical sounding, Very low-frequency sounding, Ground penetrating RADAR survey, and many more.

• Pseudoscientific Methods

These methods are also used as often as scientific methods. While they may not be officially approved by science, they can sometimes be more effective. This is because these methods are less time-consuming, and hence, more efficient for contractors in Qatar. Some of these methods include the l-rod water dowsing method, Coconut dowsing method, and Pendulum water dowsing.

1. Borewell Drilling

Once the point has been identified, then comes the step of Earth boring or borewell drilling. However, this also depends on a lot of other factors like topography, depth of groundwater, and many more. Therefore, you can deploy any of the two methods of borewell drilling: Surface drilling and Well drilling. You can find several types of heavy equipment for rent from reputed suppliers in Qatar to ensure you are able to seamlessly deploy surface drilling procedures to make your borewell. Al Abrag is one such establishment that provides high-quality and reliable drilling equipment in Qatar.

1. Surface Drilling

This step involves marking the point and the commencement of drilling. A drilling rig is set up in order to begin the drilling process. However, you need to be careful of the required depth of penetration. The type of drill bit to be used usually depends on this. Some of the most efficient drilling rigs in Qatar are available at Al Abrag. 

1. Scanning and Imaging

One of the last steps in this process is scanning and imaging the borewell that has been drilled. This step ensures there are no undetected problems remaining with the borewell hole. In fact, such post-drilling scanning and imaging have helped capture up to 80% more flaws in the drilled hole that were previously undetectable. If you wish to scan your drilled borewell hole, you can depend upon some of the most advanced imaging and scanning technology available at Al Abrag in Qatar. Some of them include High-definition cameras, Waterproof cabling, Display units, Cable pulley, Cable bobbin, LED lighting, and an analogue to digital converter.

Key Takeaway

Whether you are drilling a deep or a shallow borewell, you will always need to follow these steps. With the help of this step-by-step guide, you will also be able to make a list of all the heavy equipment you are going to need. If you plan to rent this equipment in Qatar, Al Abrag Est. is the most advisable choice. Because Al Abrag brings the latest in boring tech and decades of industry expertise with it.
