A well that uses pressure to force water to flow upwards?

Question

A.T..I.N

Answer 1

it is call artesian well.

An artesian aquifer is a confined aquifer containing groundwater that will flow upwards out of a well without the need for pumping. An aquifer provides the water for a artesian well. An aquifer is a layer of soft rock, like limestone or sandstone, that absorbs water from an inlet path. Porous stone is crushed between impermeable rocks or clay. This keeps the pressure high, so when the water finds a hole, it defies gravity and goes up instead of down.

Answer 2

artesian

although strictly it doesnt use pressure, the water pressure exists to force water up the well to the surface and beyond once the well is constructed

Answer 3

'Artesian'.
