Mosul, on May 3rd, 2017, the five waterways that control the water flow into the dam were open for the first time in the last 12 years. Since the lake is now at its highest level since 2005, the 800 m length spillway is back in action to help controlling a reservoir of more than 11 billion m3, thanks to its 13.000 m3/sec discharge capacity. After seven months of repairs, the massive Mosul Dam has been saved from impending disaster. The extensive Drilling and Grouting treatment being performed by Trevi continues at a steady pace, and in spite of the high level of water there are no significant signs of distress. Restoration of the bottom outlet and maintenance of the tunnel structures were carried out simultaneously with grouting, and now all the Dam mechanisms for water inflow control are operational.
