The Batellerie pumping station project is part of the optimization of the Rivière Neuve / Pierrettes hydraulic system, aiming to increase the existing pumping capacity in order to better respond to intense rainfall events. Located at the interface between an industrial area and a residential urban fabric, in close proximity to the Calais canal and within a heritage-sensitive site, the project must reconcile technical performance with careful urban integration.

The intervention involves the refurbishment of the existing station and the construction of an extension to double the pumping capacity. The architectural approach is sober and coherent, working with volumes and materials to create a dialogue between the existing structure and the new building.
