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.
Historic evidence indicates that wells were first constructed more than 8 thousand years ago. How sophisticated the excavations were varied from place to place. In some places, they were mere scoops made in dry watercourses, while in others they were really sophisticated in design and size. The Persian ganats and the Indian sakiehs, shadoofs, and Stepwells are examples of sophisticated designs.
Today, the types of wells in existence are very many. Common examples include driven, drilled, and dug wells. Ancient life and civilizations were dominated by dug wells. They supplied potable water but they had no pumps. These types of wells are still in use, particularly in rural regions.
Driven wells are constructed using a well hole structure. The structure is comprised of a screen and a hardened drive point. A tripod and a driver are used to hammer the drive point into the ground. Pipe sections are added to the system as necessary. Upon encountering the groundwater, all sediment created is washed from the well before a pump gets installed.
Construction of drilled wells is done using various means. Commonly employed means are table rotary, cable tool drilling equipment, and top-head rotary. Cutting action in these means rely on turning a drilling stem. Excavation may be done using hands or by machines. When hands are used, common drilling techniques employed include hand percussion, jetting, driving, augering, and sludging. Conversely, common machine drilling techniques in use include hammering, rotary, and percussion.
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.
Various pieces of information about the area must be determined before excavation of any well begins. Some of the factors that must be determined include water table depth, rate, recharge area, seasonal fluctuation, and geology. Determination of these factors is the work of either hydrogeologists or groundwater surveyors. Some of the tools and methods used to find this information include geophysical imaging, geologic maps, and electro-seismic surveying.
Affordable potable groundwater is often supplied by shallow wells in many places. However, they also pose health risks because of contamination. There are many waterborne diseases that can be spread through contaminated wells. For that reason, in the United States, driven and dug wells have bee marked unreliable.
