• 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.
