Iran faces major challenges in securing water and food for its growing population. These challenges result from both the country’s semi-arid climate and declining precipitation over the past decade.

The total long-term annual renewable water resources are estimated at 120BCM, of which about 78BCM go to surface run-off, and groundwater recharge is estimated at about 42BCM per annum, 11BCM by qanats (underground water supply systems) and springs, plus 31BCM by wells.

Dams have always played an important role in harnessing precious Iranian water reserves, and the long-term objective of Iran’s water resources development plan is based on the control and regulation of water through dams. In 2015, a total of 647 dams were in operation, of which 352 are considered significant reservoirs, with a total capacity of 48.39BCM.
