Puquios are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in
The Cantalloc puquios near Nazca, Peru. The cork-screwing funnels are for access to the underground aqueduct.
An aqueduct emerges from an underground or gallery puquios into a trench which supplies water for irrigation and domestic uses.
Except for river valleys where irrigation is possible, the desert of the Nazca Region is barren. The Pan American Highway is in the distance.
