Unique aqueducts enabling people to survive in desert conditions can be seen close to Nazca, the Cantalloc aqueducts being the best preserved examples of an ingenuous irrigation system.
In order to survive the arid desert climate of Nazca, people have had to find a way to have access to water. In the 3rd to 6th century CE, aqueducts were built to provide for year-round access to water essential for permanent inhabitation and irrigation of the area. Water running in aquifers was channelled to where it was needed using man-made underground channels. Concentrical paths leading down to these underground channels provided for direct access to the water and the underground channel for maintenance - it is claimed that the shape was based on shells.
