Surface and subterranean water - Eau visible invisible

Meetings in the Petite Agora of Grand Paris Metropolis

Invited by Grand Paris Metropolis, in the context of the third Ile-de-France Architecture and Landscape Biennial, "The Living City -  La Ville Vivante", Apur explored the challenges of surface and subterranean water at five round tables that brought together partners involved in issues concerning water: government departments, the Prefecture of the Region and Grand Paris Metropolis, local authorities, sanitation syndicates, the public water distribution corporation and managers of ports, canals and navigable waterways.
This note summarises the various presentations and exchanges with the audience. It also announced that the agency's work addressing water issues would be continued through 2026 with two professional meetings: the first to closely examine three issues linked to "water frugality, the use and sharing of water resources" and the second focusing on "Urban porosity".
