Diagram of a water well partially filled to level z with the top of the aquifer at z T. For a well with impermeable walls, the water in the well is resupplied from the bottom of the well. The rate at which water flows into the well will depend on the pressure difference between the ground water at the well bottom and the well water at the well ...
A tube well is a type of water well in which a long, 100–200 millimetres (3.9–7.9 in)-wide, stainless steel tube or pipe is bored underground. The lower end is fitted with a strainer, and a pump lifts water for irrigation. The required depth of the well depends on the depth of the water table.
An artesian well is a well that brings groundwater to the surface without pumping because it is under pressure within a body of rock or sediment known as an aquifer. [1] When trapped water in an aquifer is surrounded by layers of impermeable rock or clay, which apply positive pressure to the water, it is known as an artesian aquifer . [ 1 ]
Archaeologists in Germering unearthed a 3,000-year-old wooden wishing well, the Bavarian State Office for Monument Protection said in a Dec. 20 news release. Unlike today’s coin-filled fountains ...

Interior of a brick-lined well in Utrecht, Netherlands. A brick-lined well is a hand-dug water well whose walls are lined with bricks, sometimes called "Dutch bricks" if they are trapezoidal or made on site. The technique is ancient, but is still appropriate in developing countries where labor costs are low and material costs are high.
In 1954, that deteriorating structure was demolished, and the current Old Well — “a sturdier replica,” according to the university — was built in its place, using water supplied to the ...
