Fonts de Altea la Vella

Historic spring of Altea la Vella, located at the foot of the Bèrnia mountain range and a few meters from Altea la Vella, We walk passed it going down hill to get coffee and croissants
Most of the time there is no water coming from the opening ( middle photo) but there must be some taps between te spring and the small canals going to the orange trees.
Sometimes there is water going down usually in the morning and a hour later. Nothing
I am trying to get organized as well. New cabinet, shelfs Hopefully my system works as good as this irrigation system
