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 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.
The process of determining the most suitable spot for drilling the hole should be done by a professional consultant or an experienced driller. The criteria used to determine the suitability of the quality of the groundwater for drinking are the same as the one used by local and state government. If the wells are meant to supply waters for agricultural use, sodium-adsorption rate, salinity, and boron availability must be considered.
If the water is to be used for municipal supply, checking the quality and amount of groundwater available is vital. The well must be in a position to meet municipal pumping rate requirements. In almost all situations, the pumping rate lies between 500 and 4000 gallons per minute. Individuals homes on the other hand have very low pumping rate requirements compared to municipals. Homes require between one and five gallons in every minutes as the pumping rate requirement.
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.
