The Paris Regional Division (SADE Services agency) is building an original test installation on La Défense plaza for Veolia.

A refreshing dais

It centres on a 196 m² (14 x 14 m) dais installed at the foot of the Great Arch of La Défense, which, in summer, will refresh passers-by via a water evaporation system. Seureca and Veolia Research & Innovation (VERI) came up with the concept.

An original structure

The structure will be temporary, for the summer only, and will take the SADE Services agency team two weeks to build, including constructing a wooden surround, installing a small-diameter pipe system on a bed of sand, laying two-tone water-retentive paving stones and, finally, installing street furniture (benches, planters and bins).

SADE synergy

The waterproof HDPE tarp was laid by teams from the Centre East Regional Division, which has several years of experience in this area. Synergy just how we like it!

Trials underway

The plaza at La Défense is the third site to feature such an installation, after Bordeaux and Nice. Currently temporary, these structures could become permanent, particularly if the heatwaves we’ve been having continue to occur. It’s a market worth developing in this context – specifically in Paris, with the 2024 Olympics coming up!
