Restore the structural quality and fish migration in the Dyle river and Zuun creek.

In the Zuunbeek in Sint-Pieters-Leeuw and in the Dyle river in Leuven, we are working on restoring the structural quality, solving the fish migration bottlenecks and increasing the natural water catchment capacity.

1. Restoring the structural quality of the Zuunbeek in the centre of Sint-Pieters-Leeuw

The downstream section of the Zuunbeek runs through a densely populated area (a suburb of Brussels) with a lot of homes and large shopping centres. In this shopping district, a major part of the waterway has disappeared under the ground. At the moment, there is a lot of redevelopment taking place in this area: redevelopment of the N6 roadway, new commercial facilities, etc. This creates opportunities to reopen the waterway and improve structural quality. As a part of this project, an intensive consultation process kicked off. It will lead to a design for:

  • a new, open Zuun creek that courses through the commercial district;
  • a solution to the fish migration bottleneck.

In 2017, there was a great deal of consultation with the partners in the area (community, AWV, W&Z, company leaders, etc.). Based on the outcomes of this discussion, a number of first provisions have already been met to make a re-opening of the Zuun creek in this area a possibility in the future.

A large cased-piping tunnel has been built on the grounds of the shopping centre so that the Zuunbeek will can be turned again into an open waterway in the future. Furthermore, in the framework of the reconstruction of the Bergensesteenweg, experts have been looking into the possibility to build a large cased-piping tunnel under the road, allowing the possibility of relocating the waterway in the future. In addition, an initial design sketch has been made to visualise the impact of an open waterway in the area, and to facilitate further exchange with all stakeholders.

2. Restoration of the quality structure of the Dyle in the centre of Leuven

The Dyle runs through the city of Leuven, where it splits into five different branches. Two of these were reopened on the former Artois brewery site between the Mechelsestraat and the Vaartstraat, creating opportunities for nature to flourish and for the river to be restored.

A new park has been created with green river banks. On the edge of this part, the weir on the fourth arm of the Dyle has become a problem for fish migration. A fish ladder has been set up with educational information to create a better understanding of the situation.
