Nazca Aqueduct (Puquios System)
The Nazca aqueducts, part of the ancient Puquios system in Nazca, Peru, are pre-Incan engineering marvels. Built between 100 BC and 800 AD, they feature spiral stone walls that access underground water, regulate pressure, and allow canal maintenance. These structures demonstrate the Nazca civilization’s expertise in hydrology and sustainable water management. Many remain functional, supporting local agriculture in the arid desert.
