On 06.02.2017 the Turkish group Makyol completed the excavation of a 5.2km sewer tunnel. The tunnel was driven by a TBM EPB (diameter 6.5 m, lenght 87 m) and is part of the Super West Collector (SWC) project which aims to provide the city of Casablanca with an underwater structure to channel floodwater from Oued Bouskoura and to then discharge it directly into the ocean.
