Water is the second most important necessity of life after oxygen. The human body can survive without oxygen for a matter of minutes only before dying. On the other hand, one can go for about a week only without water before they die. The body can go without food for up to a month of more depending on several factors. When in need of Water well drilling Fort Davis Texas should be visited.

In order to access this important life necessity, people have been using a wide range of ways. One this ways is through making water wells. Water well drilling is an activity that has been ongoing for over ten thousand years now. However, until about 100 years ago, well making was ineffective since it was done by hands. People could use their hands and simple tools to dig holes in the ground to access groundwater.

In some communities, it was a culture for all individuals to participate in the well digging activity. Every person was allocated space and time to do the digging. These wells have some limitations although they are dug by hands in order to supply people with groundwater. One limitation is that they are so shallow. They extend a few feet only into the ground.

These wells were also largely risky owing to the fact that they were many feet wide. With time, there was the invention of percussion technique. The Chinese were the earliest individuals to utilize the method. An estimation is made that the Chinese were employing the method over 4000 years ago. In addition, they were able to sink wells to a depth of a few thousand feet.

Percussion driven wells started to be made in the US only in the early 1800s. This method was done using manpower, but later horses started to be used. In the mid-1800s, steam power was adopted in drilling. The coming of Industrial revolution took drilling to another level through the introduction of internal combustion engine power. Today, many companies use rotary drill bits in place of percussion drilling.

For accomplishing this task, rotary drilling is much more efficient and quieter. Contaminants can easily get into the wells and pollute the water once the well has been drilled. In order to do away with or minimize the possibility of contaminants, casings or liners are normally installed on the walls. The liners installed also play the role of preventing the walls from falling off.

The use of manual methods to draw groundwater from wells has also been stopped with the invention of water pumps. These pumps are usually capable of pumping groundwater several hundreds of feet from where they are located. However, the distance from the pump to the groundwater source has to be short since pumps cannot draw groundwater from very far sources.

It is this limitation that makes surface pumps only efficient for use on shallow wells. Otherwise, if the well is very deep, the pump has to be lowered into the well so that it is closer to the water. This way, the set up works fine and can supply enough water for residential, agricultural, and even municipal consumption.
