The 101-metre-high dam has been designed for flood control and the supply of water to downstream farmlands for irrigation. It will have a crest length of 580 metres, a drainage area of 2,762 square kilometres and a reservoir volume of 183.6 million cubic metres. The maximum discharge rate will be 4,448 cubic metres a second via a 160-metre-long spillway. Construction is expected to take about five years.

The Murwani project is the second dam contract Yuskel has won in the kingdom. The Ankara-based firm was awarded in April last year the SR 198 million ($50.4 million) design and build contract for a flood control dam on Wadi Baysh, near Jizan. The Baysh concrete gravity dam will have a height of 106 metres, with a crest length of 340 metres and total reservoir capacity of 192 million cubic metres.
