A well is a structure in the ground that is made by digging, drilling, boring or driving to reach underground waters. The waters in the well is then drawn out using a pump or containers like buckets which can be raised using machines or using hand. Excavation of wells goes way back and the types of wells constructed come in different structures. Some include qanats, shadoofs, sakiehs, and placement of linings in well shafts to enhance stability. However, water well drilling Alpine has really grown too to benefit the people in that region.

The most common type of wells though traditional are the hand dug types; especially in the rural areas. This is due to the fact that they are not expensive and do not require complex technology. In fact, they may easily be constructed using easily available materials like stones and bricks for the lining.

However, in the recent excavation procedures, concrete well rings are lowered into the hole by use of machines; a method known as caissoning. This method is most efficient for deeper wells that require complex boring methods. Drilled wells differ from dug wells in that they reach deeper.

Usually, there are different types of wells that include the hand dug wells with features such as large diameter and usually dug with shovels until the water-table is accessed. Avoid accidents, they are dug horizontally. They are usually not expensive and only need manual labor and a simple technology.

Their disadvantages is that they may be hard to build in regions where there are hard rocks, easily malfunctioning due to sewage penetration. Driven wells are very simple to excavate. They are usually constructed on unconsolidated material imitating the structure of wells and consist of perforated pipes and hard drive points.

There are certain things to consider before drilling a well in Alpine. For instance, crucial details on the geology, seasonal changes, and depth of the table need to be considered. A hydro-geologist who is the individual in charge of surveying groundwater gather these information by use of electro-seismic surveying.

Certain factors are taken into account before a well is drilled in Alpine TX. These include gathering information on the geology, water-table depth and seasonal changes of the chosen area. The person in-charge of doing this research is a hydro-geologist. This is a person who surveys groundwater. They apply a number of tools. For example electro-seismic surveying.

Wells, however, come with a number of risks despite advantages like sufficient water supply at low costs. These risks include being contaminated by impurities from the surface. These leads to the rise in cases of waterborne diseases. These arise from chemicals and impurities like minerals and pesticides. These may be prevented by sealing the hole using a lid, clearing the stagnant water and cleaning the region around the hole.
