Storm water basin Vivaqua - Ganshoren

Description 

Storm water reservoirs connected to the drainage system that can collect 10,000 m³ of water during heavy storms, relieving the pressure on sewers. Buffered water is discharged into one of the main collectors in Brussels, half using a gravitational outlet, the other half using pumps.

An automated system has been fitted whereby the mechanical elements (pumps, mixers, rinsing system, …) can function entirely automatically and can be operated from the owner’s own offices. There is also a monitoring system allowing stream levels to be surveyed constantly from a distance.

Design:

  • Length ±370m
  • Breadth 8m
  • Depth of 3.5 to 6m
  • Underground, roofing plate is 1.5m below ground level
     

Construction method:

  • Concrete: 3500 m³
  • Reinforcement: 620 tonnes
  • HDPE pipes: 1000 m - diameters 400-350
