Xylem Uses Advanced Pump Technology to Increase Connectivity at Belgium's Lanaye Locks
Xylem, a leading global water technology company, has supplied an advanced pumping solution to the Lanaye Locks, a vital connector route between Northern and Southern Europe, located in Belgium. Flygt pumps and turbines will manage water levels in the canals while harnessing energy from excess water located in the Albert Canal. With the addition of a fourth lock, the system’s convoy capacity will quadruple.
The Lanaye Locks is located on the border between Belgium and the Netherlands and links the Albert and Juliana canals. The first three locks have been in operation since 1964, but two of them can only accommodate small convoy, turning the larger lock into a bottleneck for canal traffic, so a fourth pump is desperately needed. Xylem will provide five Flygt 500 kilowatt submersible hydroturbines which have flows of 18 cubic meters per second.
High water levels in Northern Europe require the network to direct output towards the Netherlands, where the water can be returned to the sea. The new project is striving to recover some of the lost energy that’s associated with the process. The five Flygt turbines have an output of 460 kilowatts and they allow energy to flow into the electrical network.
Patrick Delperdange, Senior Operations Manager at BESIX Civil Works, comments by saying, “The construction of the fourth Lanaye lock is one of the largest civil engineering projects of the decade in Wallonia. The works required the on-site production of over 220,000 cubic meters of concrete, mainly made of the gravel extracted from the river Meuse during the earthworks of 1,300,000 cubic meters. The concrete was reinforced with 15,000 tons of steel and required 200,000 square meters of formwork. BESIX finished this ambitious project within the agreed timeframe, while also coordinating the electromechanical works, among them the realization of the hydroelectric power and pumping plant.”
