The dam, which has a proposed capacity of 105 million litres (23 million gallons) per day, will be built across the 110-kilometre (68-mile) wide water-rich Wadi Dhayaqah, which extends from the eastern to southwest Muscat region.

The dam will supply around 10 million cubic metres (350 million cubic feet) of water to consumers in Wadi Dhayaqah, 5.7 million cubic metres to Quriyat, southwest of Muscat, and 19.3 million cubic metres to the capital itself.

Some 20 international and local firms have expressed an interest in pre-qualifying for a contract to provide consultation for constructing the dam, the largest ever such project envisaged by Oman's ministry of water resources.
