Development of the "Carré de la Réunion" wastewater treatment plant (France)
3D hydraulic characterization of the structure operation
Client: SMAROV - Model scale: 1:15
Context
SMAROV, the Versailles west regional development agency, has launched an ambitious programme to upgrade the "Carré de Réunion" wastewater treatment plant; numerous hydraulic structures are to be built to improve the flood protection and reduce the environmental pollution during heavy rainfalls.
In the frame of the complete design and construction supervision assignment awarded to Artelia (previously Sogreah), the use of a scale model was proposed to study the operation of the decontamination tank.
Description of the physical scale model
The model built for this study was quite long (>25m), made of plywood with some specific parts made of transparent Plexiglas.
Aims of the physical scale model
- Check the distribution of flows between the various channels
- Optimize the design of the overspilling weirs
- Study the operation of vertical shafts
- Measure the velocity pattern
- Optimize the crest level of the sidewalls
