The Molenbeek is a tributary of the River Zenne. The Molenbeek valley and its tributaries, the Zevenborrebeek and the Kwadebeek, form a valley system that extends over a distance of around 13 kilometres between Beersel and Sint-Genesius-Rode.  The land development project is a wide-ranging one that includes a large number of measures to improve the Molenbeek valley with regard to the landscape, recreation, ecology, etc. As part of the Belini project, we are putting together a number of measures to improve the water system.

In the past, this area frequently had to contend with a number of major problems in terms of water management:

• The watercourses lacked natural character, which had a negative impact in terms of wetland biodiversity.
• The area’s main bodies of water flowed underground through artificial pipework infrastructure.
• Barriers impeded the migration of fish (which had a negative impact on biodiversity).
• Flooding problems due to lack of natural water retention areas.
