The road, a grey two-way street with no cycling infrastructure, suffered from regular waterlogging in the densely built-up area. A coalition comprising the Antea Group, Aquafin, De Lijn, the Roads and Traffic Agency (AWV) and the utility companies designed and realised a 'rainwater axis', which discharges the rainwater in a controlled and gradual manner into the Edegem brook.
The water is infiltrated as much as possible into various wadis, infiltration basins and a large new playground in the park, with the famous 'soup bowl' forming a landmark in the area.
A buffer basin was installed below the soup bowl in order to slow down the flow of water from the streets higher up. Further down the road, a channel was created to drain the surrounding built-up area and that of the technical institute. The combination of interventions represents a major step forward and sets a new precedent for Flanders.
Bringing the water above ground was not without its challenges; the team had to work hard to allay local residents’ concerns about odour nuisance, litter and vermin. This was easier when the benefits of the redevelopment became visible: a higher quality living environment that provides space for residents to meet up and relax.

Conference 11 May 'Resilient Spaces': Edegemsesteenweg rainwater axis
The infiltration of rainwater in the public domain is possible, as shown by the Rainwater axis in Edegemsesteenweg. Various interventions not only ensure water infiltration and buffering, but also the anchoring of rainwater in the public space.
