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.
Horizontal well drilling is quite common and has been exercised over the years. As a matter of fact, the most ancient wells are horizontal in nature. These wells are called Qanats and are situated in what is modern-day Iran. They were dug by human hands in the ancient Empire of Persia. The wells provided water that was used for municipal, agricultural, and domestic use in the empire.
Apart from being used as a supply for water, wells are also drilled for other reasons. One of them is extraction of oil and gas. Other wells, known as monitoring wells, are drilled in order to monitor the quality and quantity of groundwater. Other reasons for drilling wells include investigation of subsurface conditions, shallow drainage, water disposal, and artificial recharge.
Determining the correct location for the hole is the first activity in the entire process of drilling the well. The purpose the well is meant to serve is a major determinant of where the well will be located. In case the well is supposed to provide groundwater for domestic use and drinking, then the quality of water and long-term availability are the two most considered factors.
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.
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.
