Refresh the city

The fight against global warming is one of the major challenges for the City of Paris. To cope with the increasingly high and frequent temperature peaks in the capital, Eau de Paris imagines and implements concrete solutions that protect the health and improve the comfort of Parisians.

Innovative fountains to cool the city

Cooling the city during heat peaks is a major challenge for the City of Paris. To meet this challenge, Eau de Paris has imagined and designed, with the help of its service providers, “2 in 1” fountains: fun devices that combine water distribution for drinking and misting.

These innovations embody Eau de Paris' commitment to finding new uses to make Paris a more resilient and sustainable city.

5 Wallace fountains were equipped in 2021 with an invisible misting system, designed by the Eau de Paris teams. In case of high heat, misting is triggered automatically every 4 minutes. By 2026, around fifty Wallace fountains should be equipped with this system.

These fountains are integrated into the network of 1200 Parisian public fountains supplied and maintained by Eau de Paris.

Non-potable water, an asset for a greener and cooler city

If it cannot be consumed, undrinkable water is an asset for making Paris a cooler city, capable of adapting to the effects of climate change.

Non-drinking water emits 7 to 8 times less CO2 equivalents per m3 distributed than drinking water.

Untreated, non-potable water in Paris is used for various urban uses, such as watering the capital's many green spaces. It thus plays a central role in the refreshing and resilience of the city.
