“ Together with our partners, we replace the foil at the bottom of the reservoir to make it 100% watertight again and remove phosphate-rich sludge. We also install 60 kilometers of cables under the foil to quickly detect potential leaks. During the works, we reuse as many materials as possible to limit the impact of transport on the environment ,” Jan De Nul said.

The works are expected to be finalized by the end of this year. The reservoir is planned to be back in operation by mid-2027.
