Reducing CO2 emissions by 95% during the Lauwersmeer-Vierhuizergat dyke reinforcement
The Noorderzijlvest Water Authority will start work on reinforcing the Lauwersmeer-Vierhuizergat dike in 2023. By using electric machines, 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 machines with lower emissions. This is an important incentive for making equipment in the civil engineering sector more sustainable.
Electric and hydrogen-powered trucks, cranes, trailers, and generators
This involves the use of a hydrogen truck, various larger and smaller cranes, tipper trucks, tractors with trailers, and generators. This electric equipment saves around 600,000 liters of diesel. That is a reduction of 22% on 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 compared to the use of regular equipment to dyke the dyke .
Reuse of raw materials and greater biodiversity
In addition to limiting emissions, we are strengthening the dyke reusing raw materials and contributing to biodiversity. Various nature measures have been included in the project to promote biodiversity, such as fish migration and a freshwater-saltwater transition zone. But also artificial reefs for the dyke the natural transition) and the development of a natural salt marsh. We are sowing part of dyke with flower- and herb-rich grass. Furthermore, the dyke has been designed dyke . This means that almost 100% of the asphalt, clay, and copper slag blocks from the existing dyke will be dyke in the new dyke. As a result, far fewer new raw materials will need to be supplied.
Dyke reinforcement Lauwersmeer dyke-Vierhuizergat
Starting in 2023, the water authority its partners will reinforce the Lauwersmeer dike in Groningen. This involves 9 kilometers of sea dyke between Lauwersoog and the Westpolder. While reinforcing the dyke, we will also be working on extras for nature, recreation, and traffic. This will ensure that we are well protected against flooding in the future. At the same time, we will enhance nature, recreation, and accessibility in the area. Read more at lauwersmeerdijk.noorderzijlvest.nl.
Flood protection program
This dike reinforcement is part of the Flood Protection Program. In the HWBP, the 21 water boards and Rijkswaterstaat are working together on the largest dike reinforcement operation ever since the Delta Works. At least 1,500 kilometers 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 recreate safely.
