Because the level (height) of water contained in a constrained the aquifer is higher than the point at which that aquifer is tapped. The head of pressure therefore causes the water to rise up and come out of the ground at the point of tap (the well).

Naturally flowing water wells are called "Artesian" wells.An artesian well
Because of freely moving of electrons in the material
Electrons flow around the nucleus
Gas particles flow freely but are still attracted to each other. This is because the particles are very far apart.
Put in a well head with a tap. Or make the well head very tall so that it is higher then the artesian pressure.
An Artesian well, or commonly a spring, will flow of their own accord.
An Artesian Spring
An artesian bore is a borehole drilled in an artesian basin to produce an artificial artesian well.

what is an artesian well
An artesian well is formed when it is located in center and surrounded by hills . The table of underground water tries to come out of the well due to the opening in the center with pressure. This type of well is called as artesian well.

An artesian aquifer is a confined aquifer containing groundwater under positive pressure. This causes the water level in a well to rise to a point where hydrostatic equilibrium has been reached. A well drilled into such an aquifer is called an artesian well.
