Lock and weir in Harelbeke, Belgium
The largest part of this project consisted of building the new lock and constructing a double weir. The old lock was replaced by a new, larger one of 230 metres long, 12.5 metres wide and 4.7 metres deep. In order to guarantee passage for shipping during the works, a temporary lock was first built next to the old lock. The old lock could then be demolished to build the new lock.
Next to the lock, a double weir with turbines was built. These turbines now provide the necessary electricity to operate the lock in an energy-efficient manner.
This lock is part of the larger Seine-Scheldt project, an inland navigation project of the Flemish Waterway Authority, supported by the European Union. With this project, Flanders wants to offer a fully-fledged alternative to land-based goods transport. An improved inland navigation with the goal of less traffic congestion, more safety and a cleaner environment.
