Rain creates artesian aquifers in the same way that rivers carve canyons. Take ourGroundwater true/false quiz, When pressures in groundwater aquifers are high, old lost wells may begin flowing freely at the land surface. Water builds up in this area between impermeable rocks, like clay which causes pressure to build. When an artesian well is drilled, water will force its way through to the surface once the aquifer is punctured resulting in an upward flow of water. Are They The Same As Natural Springs? Natural springs are similar to Artesian wells. Or to pressurize a closed casing until it reaches the actual delivery pressure of the surrounding aquifer.

Speaking with more precision, an artesian well is one in which water rises in the well casing high enough to deliver water to a building, and higher than the local groundwater table, due to water pressure within the drinking water aquifer, but stopping below the top of the well casing itself. They differ in the following parameters: A sand well is not drilled so deeply and can reach water-saturated sands after only 15 m. A fully equipped well is much cheaper than an artesian well, and this attracts many segments of the population. For more information, read ourprivacy policy.
