Upgrading the Afsluitdijk

26 June 2018 00:00

Although the XblocPlus is called the Levvel bloc on this project, it is still a BAM Infra innovation. Some 75,000 innovative concrete blocks are going to offer protection on the Wadden Sea side. These blocks weigh some 6,500 kg each, are very strong, weaken waves, and are easy to install. And they also attract sea life.

Draining water when it is possible, pumping when required.
There will be new drainage sluices in the intermediate islands of the dyke to drain water towards the Wadden Sea. Since draining will not be possible when the water level in the Wadden Sea is high, two large pumping stations will be installed at Den Oever. They have low energy consumption and are fish friendly. And to compensate for the energy consumption, a 2.7-hectare solar panel park will be installed at Den Oever.

Fish migration
In order to restore the connection between the Wadden Sea and the IJsselmeer lake for migrating fish, De Nieuwe Afsluitdijk (a partnership between the provinces of Fryslân and Noord-Holland and the municipalities of Súdwest-Fryslân, Hollands Kroon and Harlingen) is going to install a fish migration river surrounded by an ecological area. Levvel will construct the opening in the Afsluitdijk for this fish migration river.
