Strengthening dyke between Gorinchem and Waardenburg

Graaf Reinaldalliantie has received EUR 350 million to implement the strengthening of the dyke between Gorinchem and Waardenburg in the Netherlands over the next 5 years.

Water Board Rivierenland, the client and partner in this alliance, received funding for this through the Flood Protection Programme.

Graaf Reinaldalliantie is a partnership of Water Board Rivierenland with the contractors Heijmans, GMB and de Vries & van de Wiel and with Royal HaskoningDHV as an advisory party.

Since the new safety standard was set, the dyke reinforcement between Gorinchem and Waardenburg is the first major project on the north side of the River Waal to be implemented.

It involves 23 kilometres of dyke, from the Dalemsewal in Gorinchem (province of South Holland) to the crossing with the A2 near Waardenburg (province of Gelderland).

The project is one of the top 10 most urgent projects in the Flood Protection Programme.

In June of this year, the actual groundwork will begin.

The work will be carried out in parts. This means that the entire process will not take place at the same time, but the work will be done per dyke section or cluster of dyke sections.

During the implementation, the environmental managers will continue to closely involve the immediate environment in the work.

In 2026, the dyke must once again be flood-proof.
