Ancient Nazca Aqueduct System

This Nazca aqueduct, part of the Puquios system in Nazca, Peru, exemplifies pre-Incan engineering (100 BC–800 AD). Featuring spiral stone walls leading to a central water channel, it demonstrates the Nazca civilization’s hydrological expertise. Designed for water access, canal maintenance, and pressure regulation, these structures tapped underground aquifers, sustaining agriculture in the arid desert.
