Coastal maintenance at Castricum aan Zee and Heemskerk has started

Rijkswaterstaat has started coastal maintenance at Castricum aan Zee and Heemskerk. On the seabed off the coast 3 million cubic meters of sand applied. Contractor Van der Lee will carry out the work from June 2022 until June 2023. By adding extra sand, we keep the coastline in place and Noord-Holland remains protected from the sea.

The sand is transported with a special dredger, a trailing suction hopper dredger, applied on the shallow foreshore, between beach pole 43 in 52. Most sand will be deposited through the hatches under water, but the last part is sprayed over the water ('rainbow'). The sand is deposited on the seabed a few hundred meters from the beach. There is no hindrance for visitors to the beach. Boaters must keep a safe distance from the ship, at least 50 to 100 meter.

Need for coastal maintenance

We maintain the Dutch coast together with the water boards. we do not, then we will lose part of our land to the sea. The beach and the dunes are our main protection against the sea. By regularly applying new sand on and just off the coast, we keep the coastline in place here. We also ensure that the coast can grow with the rise in sea level. That's how the Netherlands stays well protected from the sea. To maintain the coast, Rijkswaterstaat uses annually on average 12 million m3 sand from the seabed at about 10 km from the coast.

Water. Because. To work. Rijkswaterstaat.
