How does a free flow well work?

A free flow well, also known as an artesian well, operates by tapping into a confined aquifer that is under pressure. When a well is drilled into this aquifer, the pressure allows water to rise naturally to the surface without the need for a pump. This occurs because the water level in the well rises above the top of the aquifer due to the pressure difference. As a result, water flows freely from the well, often creating a visible fountain effect.
