The Bassin des Chasses pumping station project is part of the optimization of the Rivière Neuve / Pierrettes hydraulic system, aiming to improve stormwater management and reduce flood risks. Located within a natural area and in the protected setting of a historic monument (Fort Risban), the project addresses strong landscape and heritage preservation challenges, while ensuring efficient discharge of water towards the maritime environment during intense rainfall events.

The project proposes a setback from the riverbank in order to preserve landscape continuities. The architecture is sober and contemporary, using durable materials in response to the heritage context, with particular attention given to the integration of technical equipment and the ecological and landscape treatment of the surroundings.
