ABU HAMOUR water drainage tunnel, qatar

Up to 16.5m3 of water flows through the Abu Hamour drainage tunnel every second, meaning it could drain an Olympic swimming pool in around two and a half minutes.

The project involves the design and construction of a storm water tunnel and access shafts in Doha along the route of the proposed F-Ring Road from Musaimeer Street to the New Doha International Airport.

The Abu Hamour tunnel is 9.5km-long and 3.7m-wide and the location  — a hot and humid environment with a high concentration of chlorides and sulphates in the soil and groundwater – meant an innovative design was required to achieve the specified design life of 100 years.
