Avant-Senne basin: study of the potential disconnecting of the rainwater

Discover the detailed study as well as the action plan on the potential disconnecting of the rainwater in the Avant-Senne basin, the result of an exciting collaboration between the municipalities of Saint-Gilles and Forest, Urban, Brussels Environment and the consulting office Elleny/Infra Services.

This study aims to identify the possibilities for integrated rainwater management (see definition in Urban's Public Spaces Manual), so as to avoid overloading sewers and risks of flooding. 

Brussels Environment therefore called on the consulting office Elleny/Infra Services to carry out an in-depth study in two flood-prone areas:

  • the Molenbeek basin (Brussels City and Jette)
  • the Avant-Senne basin (Saint-Gilles and Forest)

The study of this last area, the Avant-Senne basin, was funded by three urban renewal programmes, coordinated by Urban’s teams:
