Water well refers to a shaft, hole, or an excavation into the ground that is used to extract groundwater from the subsurface. After the excavation has been done, pumps or other means are needed to extract the groundwater in most cases. However, in other cases, the groundwater may flow out to the surface naturally without the need of a pump. When in need of Water Well Services Hill Country should be visited.
Wells which produce groundwater naturally in the absence of artificial intervention are known as flowing artesian wells. In almost all situations, wells are dug vertically into the ground, but this is not always true. At times, wells are excavated at an angle or horizontally for the water to be accessed. For use in bank filtration, wells are usually drilled horizontally.
Over the years, horizontal well drilling has been a common process used in various cases. As a matter of fact, horizontal wells are the oldest wells known to man. Qanats, as they are referred to, are located in modern-day Iran. These wells were dug in the Old Persian Empire by hand. The wells were used to supply water for agriculture, municipal and domestic use in the Empire.
Apart from being used for water supply, there are other purposes as to why wells are drilled. Extraction of oil and gas is one of the other purpose served by wells. There are wells, known as monitoring wells, which are dug for the purposes of monitoring quality and levels of groundwater. Waste disposal, investigation of subsurface conditions, artificial recharge and shallow drainage are among the other reasons wells are dug.
The process of drilling wells usually starts with the determination of the most suitable spot to locate the hole. The location of the well is in large part influenced by the purpose that the well is supposed to serve. When the well is meant to supply water for drinking and other domestic use, the two mostly considered factors are long-term groundwater supply and quality of the water.
The process of determining the most ideal spot to drill the hole has to be done by an experienced driller or a professional consultant. The criteria to be employed to assess the quality of groundwater meant for drinking are similar to the ones enforced by state and the local governments. In the case that the wells are to be used to supply water for agriculture, sodium-adsorption rate, boron availability, and salinity have to be considered.
If the hole is supposed to supply water to the entire municipal, apart from groundwater quality, the amount of water ought to be considered. The well ought to meet the municipal pumping rate requirements. Mostly, 500 and 4000 gallons per minute is the pumping rate requirement in many municipals. As for homes, the pumping rate requirement is normally low, and could be as low as 1 to 5 gallons in a minute.
To establish the quantity and quality of groundwater that will be adequate, drillers depend on prior knowledge and experience. Drillers normally look at reports done by people who have drilled wells in the same area. If wells have adequate amount of waters in a given area, it is concluded that new wells will also have adequate waters of good quality.
