Year : 2006-ongoing Location : Tripoli, Libya Client : Metis Ltd. (Libya Water Authority) Partnership : -

Wadi Rumman and Wadi Abu Shaybah dam is designed and constructed to protect the irrigation areas at the downstream side.  Besides the flood control, which happens periodically, Wadi Rumman and Wadi Abu Shaybah dam will provide additional water for irrigation. Another purpose of the dams is to store the water in the aquifer in case the ground condition is suitable. Some of the technical specifications of the dams are:

• Data collection and evaluation.
• Geotechnical investigations
• Detailed design of the dams and their components (such as road, derivation canal, cofferdam, spillway, bottom outlet, intake structure)
