Trevi starts Mosul Dam preparations

Mosul dam

Trevi is starting preparations for its £217M contract to repair the Mosul Dam in Iraq.

Earlier this year the US Embassy in Iraq warned that the dam faces a “serious and unprecedented risk of catastrophic failure” with little warning. The Embassy said that if the 11.1bn.m3 dam collapses some areas could be inundated by up to 21m of water within hours.

During the repairs around 450 Trevi engineers and staff members will be on site, protected by the Italian military. Tomorrow (Friday) construction for the workers’ compound will start, work on the actual dam is expected to start towards the autumn.

A statement from Trevi on the contract said said: “Specifically for this important project an intense level of drilling activities and injection of cement mixtures will take place for the consolidation of the foundations of the dam. It must be also noted that other activities such as the repair and maintenance of the bottom outlet tunnels will also take place as they are currently damaged. While initiating the first steps of mobilization, specialized courses and training for technicians and local staff for the use of Soilmec drilling rigs will also commence.”

Following the so-called Islamic State attack on the facility in August 2014, maintenance operations were disrupted.

The dam was built without the grouting work needed to control seepage through the dam foundations. Instead, the designer chose to build a grouting gallery that would allow grouting to continue after the dam began operating.
