Puquios (spring, well) are ancient underground aqueduct systems that allow water to be transported long distances in hot, dry climates without much of the water being lost to evaporation. They are known locally as socavones (shafts) and were scattered throughout the oases of the Atacama.
In the 21st century, puquios still exist in the valleys of Azapa and Sibaya, as well as in the oases of La Calera and Pica.
