An artesian well is a pumpless water source that uses pipes to allow underground water that is under pressure to rise to the surface. This type of well seems to defy gravity because the pressure that builds up between layers of rock gets relieved when the water finds a path to the open air.
When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water (rechargeWater added to an aquifer. For instance, rainfall that seeps into the ground (infiltration).f a well is drilled into this pressurized aquifer, the internal pressure might (depending on the ability of the rock to transport water) be enough to push the water up the well and up to the surface without the aid of a pump, sometimes completely out of the well. This type of well is called artesian.
