en.Wedoany.com Reported - Belgian marine engineering group Jan De Nul Group, on behalf of Flemish water company De Watergroep, is collaborating with Aertssen Group, DEME Group, and Boskalis to renovate a 6.4 billion-liter drinking water reservoir near Ghent, Belgium. The reservoir has been in operation for 50 years, with renovation expected to be completed by the end of 2026, and the reservoir is planned to resume operations in mid-2027.
Jan De Nul Group, headquartered in Capellen, Luxembourg, is an international marine engineering contractor founded in 1938, with operations spanning dredging, land reclamation, marine engineering, and environmental engineering. De Watergroep is the largest drinking water supplier in the Flemish region, serving over 3 million people across 177 municipalities in Flanders, Belgium. Boskalis, headquartered in Papendrecht, the Netherlands, has over 115 years of experience in dredging and marine engineering and is one of the world's leading dredging and marine engineering contractors. DEME Group, headquartered in Belgium, is a leading global contractor in dredging, offshore energy, and marine infrastructure engineering, with over 145 years of experience. Aertssen Group, headquartered in Stabroek, Belgium, is a multidisciplinary engineering contractor with over 60 years of history, specializing in complex civil engineering, heavy lifting, and transport logistics.
According to Jan De Nul, the renovation will replace the reservoir's bottom liner to restore 100% watertightness and remove phosphate-rich sludge. To enhance leak detection capabilities, 60 kilometers of cables have been laid beneath the liner. Materials are reused as much as possible during construction to reduce the environmental impact of transportation. The joint renovation of the Ghent reservoir by these four leading international dredging and engineering companies demonstrates the collaborative capabilities of Belgian and Dutch enterprises in large-scale water infrastructure restoration, providing a practical reference for the sustainable renewal of European drinking water infrastructure.
