On the Wadden Sea side, the causeway will be raised and reinforced with new facing. For this work, the consortium will use ‘Levvel blocks’, innovative concrete elements that have been developed specially for the Afsluitdijk. Natural discharge if possible, pumping if necessary. An opening for a fish migration river. These are just a few of the innovations for the Afsluitdijk in the next few years. Together with Levvel – a consortium comprising Van Oord, BAM, and Rebel – Rijkswaterstaat (part of the Dutch Ministry of Infrastructure and the Environment and responsible for the design, construction, management and maintenance of the main infrastructure facilities in the Netherlands) will launch the project at the end of 2018. On Monday 23 April 2018, the Rijkswaterstaat and Levvel presented the designs to the media and to a large group of stakeholders who have been closely involved in planning in the past few years.

Goals

The drainage locks at Den Oever will be expanded with new locks in between the island sections. This will allow more of the water that enters the IJsselmeer from the River IJssel to be discharged into the Wadden Sea. If the water level in the Wadden Sea is high, then natural drainage is no longer possible. Levvel is therefore building two large pumping stations in Den Oever. The pumps will operate with very low energy consumption and are fish-friendly. They will be powered sustainably by 2.7 hectares of solar panels near Den Oever.

Deliverables

With these measures, Rijkswaterstaat and Levvel will ensure that the Afsluitdijk can again withstand the force of the water until at least 2050.
