Toulouse airport bets on depollution
Toulouse-Francazal airport will sustainably manage its rainwater thanks to Tencate Aquavia’s depolluting aquatextile.
TenCate AquaVia, a French eco-business, offers a aquatextile to clean up rainwater during infiltration. The extension of the North area of Toulouse-Francazal airport, which is scheduled to come into service soon, will benefit from this technology.

Based in Cugnaux (31), Toulouse-Francazal airport has chosen to manage its rainwater sustainably. A significant development that leads to storing and then infiltrating stream water by rehabilitating and revegetating an open-air basin nearby. The latter will be used to collect all the runoff water from the watershed’s traffic routes, including roads and an aircraft parking area, on a waterproofed surface of more than 90,000 m².
Infiltration at the source of rainwater is indeed a solution increasingly used by territories.

This policy, which allows the evacuation networks to no longer be clogged and the water to return to its natural cycle, must nevertheless be accompanied by a depollution stage to eliminate rainwater from the hydrocarbons evacuated during runoff. ” Infiltrating is a good thing, infiltrating clean water is essential insists the president of TenCate AquaVia, Jean-Pascal Mermet.
Sustainable stormwater management requires a uniform approach: depollution during infiltration. This is the whole point of the aquatextile designed by the company.
On the airport site, the volumes of rainwater that will run off on the catchment area will pass through the infiltration basin from which they will be depolluted by the GeoClean aquatextile. The latter was applied to the bottom and slopes of the basin, then covered with a layer of topsoil. Deployed over more than 5,400 m², the GeoClean aquatextile will treat hydrocarbon pollution and allow the infiltration of clean water to preserve soil biodiversity. ” We created GeoClean to greatly reduce the environmental impact linked to human activities and restore the ecological state of infiltrating waters “says the leader of the company.
