Aqueducts and manmade wells built about 1,500 years ago in Peru by the Nazca people are still in use today and supplying water for daily living and irrigation to people in desert areas near the modern city of Nazca.
The Nazca people had only very narrow, rocky valleys to live and grow their crops in, so they implemented an Advanced Hydraulic Engineering system that greened their lands and helped them prosper, says an article about the aqueducts at EnPeruBlog.com.
They are known as the Aqueducts of Cantalloc or in Spanish Cantayo. The accomplishment of creating them was far greater than the Nazca lines that are so famous around the world.
About 1,500 years ago, the ancient people made between 30 and 50 underground channels to carry water from rivers upstream from the valley and from mountain springs to their crops and cities. They dug the channels and lined them with stones and wood and then reburied them. They stretch for kilometers, the En Peru website reports.
