Revolutionary Guards builds the largest water tunnel in the Middle East

Iran says its engineers have completed a water tunnel in its central Qom province that is believed to be biggest in the Middle East.

Experts from Iran's Islamic Revolution Guards Corps (IRGC) carried out the construction of the 43.7-kilometer-long tunnel (27.3 miles) to transfer water from the Dez River to Qomrud River.

IRGC commander Major General Mohammad Ali Ja'fari and Iran's Energy Minister Parviz Fattah inaugurated the project on Thursday.

The tunnel aims to transfer 120 million cubic meters (4.2 billion cubic feet) of water from the Dez River to the central Iranian desert per year.

The project has taken five years to complete.

Desert provinces in central Iran have faced a shortage of water over the past year due to below-average rainfalls, although recent heavy rains have averted a second year of drought.
