Did you know that underground aquifers harbor 97% of the world water? Water is the most sought after liquid and it has a wide range of uses from drinking, domestic, agricultural to drive machines in factories. To supplement water from other sources such as lakes, river and rain there is a need to drill wells. In this case there are several tools for water well drilling and I will undertake to discuss some.
Before indulging into these tools it is wise to interrogate some of the factors that should be considered when drilling a well. The cost-benefit analysis will be of utmost help in comparing drilling a well to using other water alternatives. Different town and cities have varying requirement that must be met, so it is good that one is conversant with these rules. Not all areas can produce water, hence it is good to conduct a geological survey to avoid in engaging in non feasible endeavors.
There are two types of tools and these are the cable tools and the rotary drills. In some instances, some alternatives may be used. A good example is when the surface involved is very soft and a shallow well is needed. In this case a shovel can be used to loosen the earths surface as well as to lift it outside the hole. The function of the cable tool is to fracture and loosen the earth to facilitate the lifting out of resulting soils. The cable tool consists of a heavy string with bits and they are the one that is dropped severally in the same area when drilling. This result in a loose earth that is ready for lifting out.
The bailing bucket functions by lifting out the earth from the whole. Sometimes the bucket may be as simple as the ordinary bucket or a complex one with a one-way valve on the bottom. To facilitate the lifting out of the drill cuttings resulting from the activities of the cable tool water is added to them to make the process easier.
When the surface involved is very hard and rocky percussion cables may be used instead of rotary drills. However, unlike the rotary drill, the percussion cables are very slow and very costly. They are however very effective in areas where the rotary drills would have spent lots of time drilling through the rocks.
Rotary drills are not that effective when the surface involved is very rocky and in this case percussion cables are used. Some disadvantages associated with these cables are that they are slow and costly when compared to the rotary drill. They are however less costly and faster in rocky areas where the rotary drills can spend ages and sometimes fails to accomplish the task.
After drilling is done, it is very vital to have the well sealed to prevent the entry of pathogens and other disease causing micro-organism. Caution should be exercised when constructing the casing as if poorly constructed it poses great, danger not only to human beings but also to animals. It is advised that a concrete seal be constructed as it is by far much durable.
Lastly, the value of water in our life cannot be underestimated and as they say water is life. However, in some areas the water may not come out easily and this makes it imperative to use tools such as the rotary drill that can dig up to 300 meters deep into the ground. The area where the well is to be dug should be assessed and after the well is dug it should be protected from pathogens and other dangers.
