The rainwater of some 500 hectare paved surfaces that needs to be drained off, the mains water that is used by an average 50,000 passengers a day and the large amounts of wastewater are just a few examples.
The bulk of the wastewater ends up in our own wastewater treatment plant. What is left is treated at public plants.
Wherever possible Brussels Airport makes sure mains water is replaced by rainwater. On average, we collect some 5 Olympic swimming pools of rainwater every day.
Did you know that part of this rainwater is used to sprinkle the nearby Brabantse Golf Course?
