But he gave no details about how such a vast operation would be conducted.
Tehran nestles on the southern slopes of the Alborz mountains and has hot, dry summers, usually relieved by autumn rains and winter snowfall.
Reservoirs run dry
Tehran is by far the country’s biggest city and its inhabitants use three million cubic metres of water per day, according to local media.
The main Amir Kabir dam on the Karaj River, one of five reservoirs serving the capital, is running dry and holds only 14 million cubic litres, according to Behzad Parsa, director general of the Tehran water company, cited by the official news agency IRNA.
During the same period last year, the reservoir held 86 million cubic metres, he added, but now it only has enough to maintain supplies to the Tehran region for less than two weeks.
On Saturday (local time), state television broadcast images of several dams, serving the central city of Isfahan and Tabriz in the northwest, showing significantly lower water levels compared to previous years.
Hassan Hosseini, the deputy Iran’s second-largest city Mashhad, told the IRNA agency on Thursday (local time) that night-time water cuts were being considered to address the water shortage.
And over the summer in July and August, two public holidays were declared in Tehran to save water and energy, at a time when power outages were almost daily during the intense heatwave.
