A
water well refers to an excavation that is made into the ground for the
purpose of accessing groundwater contained in underground aquifers. The
excavation or structure is constructed through boring, digging,
drilling, or driving using mechanical or manual means. The water
contained in wells may be pumped out using machines or may be drawn
using buckets and other forms of containers by hand. When in need of the
best water well services TX is the right state to visit.
According to historic evidence, the first well was constructed over eight thousand years ago. The structures varied widely in sophistication with some comprising of simple scoops constructed on dry watercourses. Conversely, others incorporated a high level of sophistication and size that they powered civilizations and livelihood in various ancient cities. Some major examples of sophisticated wells include the ganats of Persia and the shadoofs, sakiehs, and Stepwells of India.
Many and diverse kinds of wells exist today. Drilled, drilled, and dug wells are some of the most common examples. In ancient times, the most common type was the dug well. These structures were a source of livelihood to many people and they powered civilizations. They supplied potable groundwater but lacked pumps. In most rural areas, dug wells are still very common.
Constructing driven wells uses well hole structures. The main components of the structure are screens and drive points. Driving of the drive point into the ground is done using tripods or drivers. As the driving process continues, sections of pipes are added as it is needed. Before a pump gets installed after reaching groundwater, sediment generated during the process has to be washed away first.
Drilled wells are constructed through various means. Some of the most commonly used means are use of cable tool drilling machine, table rotary, or top-head rotary. All the three means employ a drilling stem which is turned to form a cutting action in the formation. Excavation may be done by hand or machine. Hand drilling methods include jetting, driving, augering, sludging, and hand percussion. On the other hand, machine drilling methods include percussion, rotary, and hammering.
There are two broad classifications of drilled wells, that is, confined or deep wells and shallow/unconfined wells. As suggested in the named, shallow wells are completed within the upper-most saturated aquifer. On the contrary, unconfined wells extend into aquifers between two impermeable strata through impermeable stratum. Wells can also be classified into two groups based on use. These two groups are production/pumping and monitoring wells.
Determination of certain factors must be done before the excavation process is started. Some of these important factors include water table depth, seasonal fluctuation, rate, recharge area, and the geology. Groundwater surveyors and hydrogeologists are the professionals whose work is to determine these factors. Some of the tools and techniques they use in their work include electro-seismic surveying, geologic maps, and geophysical imaging.
Shallow sources can supply potable groundwater at an affordable cost. However, contamination from different sources remains a major problem, which poses a health risk to people. Contaminated wells can spread a lot of waterborne diseases. In the US, driven and dug wells are considered unreliable water sources.
