Study at the basin scale 1
A 0.5
test-basin, called Loup, has been selected in a highly populated and urbanized city (Villepinte, France) located in the Seine-Saint-Denis county, close to Paris. Most of the basin is occupied by buildings dedicated to industrial activities.
The corresponding industrial building roof area represents more than 20% of the basin area (62 ha). The remaining surface is essentially covered by roads and parkings, making the basin highly impervious (close to 90%). For the rest of the study, it has been assumed that green roof can be implemented on these roofs –which are all flat.
The outlet of the basin is drained into a storage basin which water level is measured.
During a rainfall event, the storage basin outlet is closed to avoided stormwater in the sewage network.
