Infiltration galleries

Filter galleries, also called underground tunnels, are ancient techniques for harnessing groundwater in regions with scarce surface sources. These structures transport water over distances and have been used for agricultural irrigation over time.

Filter galleries, also known as underground tunnels or water catchment mines, represent an ancient method of using groundwater, especially in regions where surface sources have been scarce. This type of artificial works can transport water over great distances. There are also other examples of simple excavations in the sub-beds of ravines (groundwater that runs beneath the current of a river and has undergone a natural filtration process). Those who built filter galleries commonly used them to irrigate their agricultural fields and they are still used today.
