No more cofferdams mean return of good weather. This seems logical since this mechanism, installed near the Notre-Dame church, at the outlet of the Houille factory canal, is there to avoid joint overflows with the Meuse into which the river flows. This is due to heavy rainfall. “ The cofferdam is an anti-flooding device made up of five pumps and six metal beams. It prevents rising water levels in the Notre Dame district of Givet », explains Alexandre Prescler, the technical services coordinator. The imposing mechanism was taken out of the water this Wednesday, May 22, 2024 at 8:30 a.m. A spectacular operation which requires the help of one or two divers, eight agents, a 25-ton crane and a truck equipped with a platform to move it.

The cofferdam installed in the Meuse was removed this Wednesday morning, May 22, 2024.

This pumping device, installed since the floods of 1995, has been somewhat modernized over the years. Equipment that must be maintained fairly regularly. “ When it is installed, it is monitored regularly, especially when the water level rises. But otherwise, the rest of the year is a lick of paint on the metal beams and maintenance of the pumps. In a few days, two pumps will be overhauled. The rest is stored in our technical premises », concludes Alexandre Prescler.
