Water Treatment and Pipeline Infrastructure

Jan De Nul Group has a unique track record of many years in the design, construction and electromechanical equipment of pipeline and sewage systems and water purification infrastructure. In Belgium, the Group has built several waste water purification plants, installations for the treatment of drinking water, sewage systems and collector networks.

Here as well, Jan De Nul stands for an integrated overall project approach. Together with its own engineering and financial department, these projects are executed by own personnel only, from design over financing and construction up to the subsequent management.

The sewage water treatment plant Brussels-North is located along the Sea Canal Brussels-Scheldt, nearby the Buda Bridge, on a former industrial area next to the river Zenne. Before the implementation of this plant, the contaminated waste water fled right into the river without being purified. This changed in 2007 . In 2000 the Ministry of Brussels decided to construct a second water purification plant ‘Brussels-North’. The EPC contract was awarded to a joint venture with Jan De Nul N.V., which constructed the water treatment plant between 2003 and 2006. This second plant, with a purifying capacity of 1.1 million inhabitants, treats the waste water of the basins North and Woluwe. Since 2007 the water quality of the Zenne improved spectacularly compared to the preceding years.
