• 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.
• Built under a future road.
• Design:
o   Length ±370m
o   Breadth 8m
o   Depth of 3.5 to 6m
o   Underground, roofing plate is 1.5m below ground level
• Construction method:
o   Basin structure made of more than 1700 secant piles
o   Concrete: 3500 m³
o   Reinforcement: 620 tonnes
o   HDPE pipes: 1000 m - diameters 400-350
o   2 pumps 35
