Connection of the Outfall Sewer from MontpellierConnection of the Outfall Sewer from Montpellier

This small but highly-technical operation was intended to connect the outfall sewer from Montpellier (11 km in diameter 1600 mm) to the land pipe, on behalf of SOGEA.

In order to do so, a sheet-pile cofferdam had to be put in place and the waters dredged to free the pipe without damaging it and a concrete invert built underwater, and dry all of it.
