Giant landfill a stone's throw from the Yvelines Olympic site: Valérie Pécresse undertakes to clean up. Waste clearance and sorting operations should begin on April 2.

In July, the site will host cycling events, a fan zone... and thousands of spectators. A few dozen meters away, the old campsite of “Parc de l'étang”, no man's land for around fifteen years, has been transformed over time into an open-air landfill.
