After passing 10.189 m under waters of the Persian Gulf the TBM has reached its final location.  

The Musaimeer Pumping Station and Outfall tunnel starts from a 40-m deep shaft on the shore and follows 10 km alignment under the water. It will drain stormwaters from the Southern part of Doha into the sea. The MPSO tunnel is reported to be the 7th longest underwater tunnel in the World. And the longest outfall tunnel in the Middle East.
