Ancient Nasca aqueducts still deliver water today
In Peru's arid Nasca desert, ancient aqueducts ingeniously tap underground aquifers to deliver life-sustaining water through hidden tunnels still used today.
The ancient Nasca civilization, thriving in Peru's desert from 200 BCE to 600 CE, engineered ingenious underground aqueducts called puquios. These spiral tunnels tap groundwater from aquifers, channeling it through natural filters before it emerges into open canals for irrigation. This gravity-fed system sustained agriculture in a region receiving less than 5 millimeters of rain annually, supporting tens of thousands of people. Over 30 puquios have been identified, showcasing the Nasca's advanced understanding of hydrology. Remarkably, several puquios remain functional today, a testament to their sustainable design and enduring legacy.
