Renovation and extension of the Neuville and Fleurieu sur Saône wastewater treatment plant.

The geotechnical context is complex: the foundations of all the structures are on reinforced soils or on raw concrete shafts.

Inclusion of the Saône centennial flood in dimensioning the structures.

The present plant must remain during the works, which requires the building shell works to be divided into four phases.

The façades of the pre-treatment building and administrative building will have a sophisticated architectural appearance: forged stone style cladding.
