Trevi is continuing its work to repair the Mosul Dam, despite an intense operation to retake the city of Mosul from so-called Islamic State militants.
The dam, located about 50km outside Mosul, is within Iraqi controlled territory.
Trevi has a £217M contract to carry out urgent repairs after a warning earlier this year from the US Embassy in Iraq that the dam was at risk of “catastrophic failure”. The embassy said that if the 11.1bn.m3 dam collapses, some areas could be inundated by up to 21m of water within hours.
Around 450 Trevi engineers and staff members are on site, protected by the Italian military. A spokesman for Trevi confirmed the work is continuing as planned.
The structure 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. Following the so-called Islamic State attack on the facility in August 2014, maintenance operations were disrupted.
Trevi is using cement grout injections as part of the consolidation of the foundations of the dam.
