Water supply tunnel between the east and west of La Réunion island

The work site is part of a larger project that involves using 30km of tunnels to transfer the water collected to the east, in the Salazie cirque, to the west coast to provide irrigation. This is the context in which our project is to build a tunnel 18 km long and 3.6 m in diameter.
