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 from which groundwater flows naturally without any artificial intervention are referred to as flowing artesian wells. In most cases, wells are drilled vertically into the ground, but that is not true in all cases. There are cases where wells are drilled horizontally or at an angle in order to access groundwater. Horizontal wells are commonly drilled for use in bank filtration.
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.
Besides being used to supply water, wells are also drilled to serve other purposes. One of these purposes is the extraction of gas and oil. Other wells, referred to as monitoring wells are drug for the purposes of monitoring the levels and quality of groundwater. Other purposes of wells include artificial recharge, waste disposal, shallow drainage, and investigation of subsurface conditions.
The procedure of drilling wells normally begins with locating the most ideal place to locate the hole. The location is greatly influenced by the reason for which the hole is dug. If the well is dug to provide groundwater for domestic and drinking purposes, the two factors that are mostly considered are the quality of the water and the long-term groundwater supply.
An experienced driller or professional should be hired for determining the best spot for drilling the hole. There are criteria which are used in determining the quality and suitability of groundwater meant for drinking. These criteria are same as the ones employed by state and local authorities. In case the structure is supposed to supply water for agricultural use, boron availability, salinity and sodium-adsorption rate are the factors to consider.
In case the hole is meant to supply waters to the municipal, besides checking the quality, the amount of water available is also important. The well must be able to meet the pumping rate requirements of the municipal. In most cases, pumping rate requirements usually range between 500 and 4000 gallons per minute. Individual homes usually have very small requirements, which can be satisfied by pumping rate requirements as low as 1 to 5 gallons per minute.
Experience and prior knowledge are important factors drillers rely on to determine if the quality and amount of water in a given well will be enough. Drillers usually study reports provided by drillers who have drilled wells in the same area. If all wells around have good quality of water in sufficient amounts, then it can be concluded that future wells will good too.
