A water well is an excellent source of water in your home. When planning to drill your well, you will want to consider things such as the competence and reliability of the drilling company, the cost of drilling the well, and the amount of space required. Another important thing to consider before your well is drilled is the drilling method to use. There are various water well drilling methods, each with its own merits and demerits. Here are some drilling methods you may want to consider for your well.
Rotary Drilling With Flush
With this type of drilling, a drill bit is rotated through a drill pipe to cut through the rock. Drilling mud is then pumped down the pipe to flush out dust, cuttings, and any other debris. Rotary drilling can drill through a wide range of rock formations, making it a more versatile option. In addition, it uses drilling mud (to flush out the dust and other debris), which can support unstable rock or soil formations. Rotary drilling with flush can also operate both below and above the water table and can drill deeper depths, which prevents contamination since shallow wells are more likely to be susceptible to contamination. The drawback of this drilling method is that you will need a good amount of water since it’s used for pumping.
This method uses pneumatic hammers to pulverise hard rocks. The hammer is driven by compressed air, which flushes out materials from the borehole as the hammer drills through. The first advantage of this drilling method is that it is ideal for drilling hard rocks such as granite. Therefore, if your ground has been found to contain granite, you may want to go for this option. It can also penetrate gravel, and it’s a fast method that will work well both below and above the water table. However, you will need an air compressor, which can increase your drilling costs. Besides, this method may cost you much more compared to other methods.
This form of drilling uses water as the main component for washing, aiding cutting, and flushing out the debris. The debris then emerges as a jet. Internal combustible pumps can also be used to facilitate the washing and cutting. Jetting is relatively inexpensive compared to the other two methods and can work well below and above the water table. However, further drilling can be hindered by boulders. In addition, it’s only ideal for unconsolidated rock formations, such as silt, clay, and sand.
