How do springs originate at the top of the hills and how do they acquire such volume of water?

One explanation that I found was rainfall but it is not apparent that rainfall could contribute to such volume of water.

Answer 1

Springs generally don’t originate at the top of hills. It’s not impossible, but, it’s not the most common place. Usually, if a spring is on the top of a hill, there are higher hills around it.

Water, even subterranean water, runs downhill. A spring is formed when more water collects in one place than can be percolated away through the underlying geology.
