Paris-Charles-De-Gaulle Airport - Stormwater segregation (France)
Stormwater segregation structure at Paris-Charles-De-Gaulle airport
Client: Eiffage - Aéroports de Paris - Scale: 1:10.33
Eiffage was appointed by ADP to build a stormwater management system covering the entire Paris-Charles de Gaulle airport. Prior to commencing the works, Eiffage commissioned Artelia to validate the design of the system’s central structure, whose aim is to segregate clean stormwater runoff and pollutants. For this purpose, Artelia suggested developing a hybrid numerical and physical scale model.
Numerical and physical scale model
- A physical scale model is used to study the entire approach zone and the intake zone. Its objective is to assess and, if necessary, correct the flows approaching the pumps in order to make sure they operate properly (avoid rotations and vortices).
- A 3D numerical model is used to study the discharge zone.
- A 1D numerical model is used to study the system as a whole.
Description of the physical scale model
The model represents:
- The upstream tank, which is connected to the supply outlet of the new segregation structure.
- The connecting outlet,
- The new structure consisting of a gravity flow channel for clean stormwater and a duct towards the pumping tank for the polluted water.
The model is designed to be modular and modifiable, should design modifications be deemed necessary.
