pre-Hispanic dams
They consist of dams made of stone and clay, which were built by the ancient Peruvians (pre-Incas) with the purpose of storing water to regulate the streams and, at the same time, allowing infiltration to recharge the aquifers and thus have water in the springs and wetlands.
They consist of dams made of stone and clay, which were built by the ancient Peruvians (pre-Incas) with the purpose of storing water to regulate the streams and, at the same time, allowing infiltration to recharge the aquifers and thus have water in the springs and wetlands. Currently some of them have received maintenance thanks to the support of some cooperation projects. In general, the dams were built in a basin or collecting basin, with a natural hollow and outlet or throat dammed with stones, clay and mud, to create artificial lagoons. Likewise, some older dams were upgraded with settlers or grit traps, regulated outlet valves, and blowdowns. In other cases, the dikes were rebuilt with reinforced or cyclopean concrete. The surprising thing about this technology, in addition to the management of the territory in terms of collection and storage, is the durability that the dams and dams have had.
