Avenue Saint-Exupéry in Thionville, between the Charles-Brenus stadium and the Jean-Pierre-Adams gymnasium is a rainwater retention basin. A large hole lined with black nylon fed by a nozzle discharging the overflow in the event of a stormy episode.
This open-air infrastructure was built by the Portes de France-Thionville conurbation (CAPFT) in 2019, in consultation with local residents whose cellars and garages were then regularly flooded. “Each time it rained, we were not at all serene. We were constantly scrutinizing the water level, ”says a resident of rue des Vergers, a perpendicular to avenue Saint-Exupéry.

The smells come from the mowing of the grass on the sports grounds which ferments but in no case from the water in the pool”. “The most shocking thing is the visual aspect”, insists a neighbor who speaks of “wart”.
If a petition has been considered for a time, the residents would prefer to find an arrangement with the Agglo. The solution of a shrubby hedge was mentioned, which would make it possible to screen without incurring excessive expenses. “The initial goal was functionality, responds in turn Brigitte Schneider, member of the community council and deputy mayor of Thionville.
