In the 5th century the aqueducts were built to provide for years round access to water essential for permanent inhabitation and irrigation of the area. Water running in aquifers was channeled 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.
In the Aqueducts of Cantayo where is open air has an S-shaped to slow down the water flow and prevent from running too fast in times of flooding. The Nazca people also constructed access points, which still now give direct access to clean and also oxygenates the water which is surprisingly fresh.
