Answer:
People do not need a pump to push the water to the surface from confined aquifers.
Explanation:
A confined aquifer occurs when groundwater is confined under a higher pressure than atmospheric pressure, due to the existence of an impermeable enclosing layer above the aquifer. Because water is at a higher pressure than atmospheric pressure when drilling a hole, water rises to the piezometric surface without the need for a pump, giving rise to an artesian hole. Thus water reaches the surface in the form of a draw, and the artesian hole is called a repellent hole.
