From the Blue Community / Blue City of Paris and its public water service Eau de Paris:
Drinking water: consumption follows the new lifestyles of Parisians.
The findings of the latest study by the Paris Urban Planning Workshop (Apur), in which Eau de Paris participated, are clear: for over thirty years, Parisians have been consuming less and less tap water. By 2024, consumption had reached its lowest level in decades. Behind these figures lies an evolution of the city, its uses, and, more than ever, challenges in guaranteeing everyone a quality water service.
In 2024, Parisians consumed over 150 million cubic meters of drinking water. That’s the equivalent of 60,000 Olympic-sized swimming pools. Impressive—and yet, it’s significantly less than before. Between 2017 and 2024, drinking water consumption in Paris actually decreased by nearly 11%, representing a loss of approximately 18 million cubic meters in seven years. And this trend goes back even further: since 1990, consumption has been declining by an average of 1.5% per year.
This development is truly good news. Sanitary equipment and household appliances have become much more efficient (washing machines, toilets), and behaviors are changing too: fewer baths, more short showers, and fewer taps left running. Parisians now consume 145 liters of water per day. This is the result of years of collective effort, awareness campaigns, and new practices, such as those outlined in the City of Paris’s Water Conservation Plan to save both drinking and non-potable water.
But part of the decline tells a different story.
