Sustainable life in a country which is mostly covered by arid and semi-arid areas has been one of the primary goals of Iranians. One of the genius water supplying systems developed by Iranians is the Qanat, an underground system which, powered by the gravity, takes the water on a journey of kilometers to settlements in arid or semi-arid regions. The construction and maintenance of qanats have been possible through social collaboration and communal management throughout millennia. Moreover, architecturally speaking, qanats have also played a great role in the construction of related structures such as dams. The Qanat was inscribed as a UNESCO World Heritage Site in 2016.
