infiltration galleries

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

Filtering galleries, also called underground tunnels or water collection 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 long distances. There are also other examples of simple excavations in the subalveas of ravines (groundwater that runs below the current of a river and that has undergone a natural filtration process). Those who built filtration galleries commonly used them to irrigate their agricultural fields and they are still used today.
