Many of major city in Iran that located in warm and dry climate, used Qanats for providing their required water from many centuries ago. Life of the city is very independent to water, but now we faced with lack of water and Qanat as our heritage had been forgotten. This Qanat went dry and changed to a dirty place for trashes! Because of wrong management the level of underground water went down and many of river and Qanat went dry. In this case also many activity around the Qanat disappeared. And that active and spirited atmosphere changed to dirty and passive condition.
