DEME has won a contract1 to implement WFD (Water Framework Directive) measures in Central Netherlands. WFD measures are projects aimed at improving water quality in the Netherlands, which are carried out by Rijkswaterstaat. In collaboration with its partner Beens Dredging B.V. (part of Beens Groep B.V.), DEME will execute Lot D at the locations Eemmeer, Ketelmeer, and Zwarte Meer. These works will start in April 2026 and are expected to be completed by December 2027.
The measures contribute to the objectives of the European WFD, which seeks to improve ecological water quality. Within Lot D, DEME, together with its partner Beens Dredging B.V., will construct ridges, brushwood dams, and sheltered zones in order to strengthen habitats, stimulate biodiversity, and improve water quality in line with the WFD objectives.
Jaap van der Weele, General Manager DEME Environmental Netherlands: “Our expertise and craftsmanship align perfectly with the specific requirements of this project. DEME has established a strong position in the Netherlands, where we have been contributing to sustainable hydraulic engineering and ecological projects for several decades. Together with our partner, we will be deploying our knowledge and innovative solutions to implement the WFD measures and permanently improve water quality in Central Netherlands. This project represents an excellent opportunity for DEME to make an impact in line with our mission of creating a more livable world and a sustainable future by delivering value for our stakeholders.”
Earlier this autumn, DEME Environmental also signed a contract to help strengthen the Lekdijk in the Netherlands. For this project, DEME is working with Heijmans and GMB within the Lekensemble consortium to reinforce the dike situated between Wijk bij Duurstede and Amerongen (WAM). Commissioned by the Hoogheemraadschap De Stichtse Rijnlanden, this essential project is part of the High Water Protection Program, which aims to protect hundreds of thousands of residents against the possibility of flooding.
