The Mehr News Agency reports that the “unprecedented” heat has caused a significant fall in water sources for Tehran, and residents will have to face periodic water cut-offs on a daily basis.

City officials have announced that with a five- to 10-percent decrease in water usage and temperatures not rising beyond 40 degrees Celsius, the water shortage problems will be resolved.

However, water usage has reportedly hit a “historic record” in Tehran, while the temperature in the capital has risen as high as 42 C in recent days.

The lack of precipitation has caused similar problems for the city of Yazd.

Experts claim Iran will face a general 10-percent decline in precipitation in the next 90 years, causing most of its underground water to dry up.
