There has a been a general idea surrounding the puquios that they were used for water collection purposes, but no one has proven this fact until this team of researchers found evidence of ancient canals and pumping systems along the pathways of holes, according to Phys.org.
Part of what makes this discovery so fascinating is how vastly this hydraulic system expands throughout the region. Not only this, but researchers believe the spiral designs would have drawn air into the canals using the wind to help push the water through the system at higher speeds. This design could possibly be evidence of the world’s first hydraulic pumps. A system this complex and expansive makes you wonder what other technologies these civilizations had access to in their time. The puquios network would have required constant maintenance and communication throughout the different groupings of Nasca people.

All of this engineering would have allowed the wells and hydraulic system to be in use all year long, supplying water to the Nasca people whenever needed. It goes without saying, but the complexity of the system and the need for extensive maintenance goes to show how technologically advanced these people were. The original construction of these wells was also so sturdy that some of them are still in use today in the surrounding region.
