The Klein and Groot Broek areas will be depoldered so that the Durme will have flooding space and tidal nature can flourish here. Here, too, the work starts with the raising of a ring dyke and the necessary appurtenances. Two pumping stations will be built on the site of Groot Broek, which will make it possible to discharge surface water collected behind the new ring dykes into the Durme during a high tide. A total of 15 structures (pumping stations, drainage sluices and culverts) will be built to ensure that the upstream discharge is managed in an orderly fashion in the new layout.

Groot Broek

In respect of Groot Broek, the works will be phased as follows:

  • Phase 1: Start the implementation of the northern ring dyke
  • Phase 2: Realisation of the southern ring dyke, including all drainage structures, pumping stations and the Beerkaaihuisje defences and structure
  • Phase 3: Depoldering & fitting out of internal area
  • Durmevallei Sigmaplan Pompgebouw De Bunt
    Pumping station Groot Broek
  • Durmevallei Sigmaplan Pompgebouw De Bunt
    Pumping station Groot Broek

Klein Broek

For Klein Broek, the phasing is divided up in the same way:

  • Phase 1: Implementation of the ring dyke
  • Phase 2: Depoldering & fitting out of internal area

Responsibilities SBE

  • The geophysical study and soil mechanical calculations of the body of the dyke, including the embankment protections
  • The design of two pumping stations with screw pumps
  • The design of various drainage structures and culverts
  • Preparation of the complete tender dossier
  • Architectural supervision of the execution of the works for the architectural pumping building of Groot Broek

Masterplan

  • Durmevallei Sigmaplan Ontpoldering Groot Broek

    Conversion Durme valley, part of the Sigma plan

    With the SIGMA Plan, the Flemish government is protecting the Zeeschelde basin in Flanders against storm influences from the North Sea and restoring rare river nature.

    Controlled flood area De Bunt

    The De Bunt project area in Hamme will be transformed into a controlled flood area with reduced tides (CFA-RTA). The controlled flood area (CFA) means that with a storm surge in the Scheldt, the area can be flooded using the new overflow dykes. The excess water from the Scheldt is buffered in the area and slowly drained back into the Scheldt after the storm.
