Reducing CO2 emissions by 95% during the Lauwersmeer-Vierhuizergat dyke reinforcement
Noorderzijlvest Water Authority implementing the Lauwersmeerdijk-Vierhuizergat dike reinforcement project in 2023. By using electric machinery, the water authority aims to reduceCO2 emissions by 95%. The water authority plans to invest water authority .2 million in the project. Together with GMB and Heijmans as the Waddenkwartier contractor consortium, regional companies have been asked to also invest in cleaner machinery with lower emissions. This represents a significant incentive for making equipment in the civil engineering sector more sustainable.
Trucks, cranes, trailers, and generators powered by electricity and hydrogen
This involves the use of a hydrogen-powered truck, various large and small cranes, dump trucks, tractor-trailers, and generators. This electric equipment saves approximately 600,000 litre . That represents a 22% reduction in total diesel consumption. The diesel we use is fossil-free and renewable, known as Hydrotreated Vegetable Oil (HVO100) diesel. The use of electric equipment and HVO100 diesel together results in a 95% reduction inCO2 emissions compared to using conventional equipment to dyke the dyke .
Reuse of raw materials and greater biodiversity
In addition to reducing emissions, we are reinforcing the dyke reusing raw materials and contributing to biodiversity. To promote biodiversity, the project includes various nature conservation measures, such as fish migration routes and a freshwater-saltwater transition zone. It also features artificial reefs in front of the dyke the natural transition zone) and the development of a natural salt marsh. We are partially seeding dyke with flower- and herb-rich grass. Furthermore dyke the dyke has a dyke design. This means that nearly 100% of the asphalt, clay, and copper slag blocks from the existing dyke are being dyke in the new dyke. As a result, far fewer new raw materials need to be brought in.
Dyke reinforcement Lauwersmeer dyke-Vierhuizergat
Starting in 2023, the water authority its partners will begin reinforcing the Lauwersmeer Dike in Groningen. This involves a kilometre sea dyke between Lauwersoog and the Westpolder. As part of the dyke reinforcement project, we will also implement additional measures to enhance nature, recreation, and traffic. In this way, we will ensure that we remain well-protected against flooding in the future. At the same time, we will enhance nature, recreation, and accessibility in the area.

Flood Protection Programma
This dike reinforcement is part of the Flood Protection Programme. In the HWBP, the 21 water boards and Rijkswaterstaat are collaborating on the largest dike reinforcement operation ever undertaken since the Delta Works. At least 1,500 kilometre dykes 500 locks and pumping stations reinforced over the next thirty years. In this way, we are working to create a country where you can live, work, and enjoy leisure activities safely. Read more at www.hwbp.nl.
