Confronted with summer season restrictions after winter drought, that is how France makes use of water
France skilled a historic drought in the summertime of 2022, adopted by an equally dry winter. Alarm bells are nonetheless ringing this 12 months because the nation braces itself for one more arid summer season. On Wednesday March 1, 2023, 4 French departments had been already topic to restrictions: Ain, Isère, Bouches-du-Rhône and the Pyrénées-Orientales. Inhabitants of those areas are forbidden to water their lawns, fill their swimming swimming pools, and farmers are prohibited from irrigating their crops.
“And the quantity [of departments facing restrictions] will inevitably develop,” warned Ecological Transition Minister Christophe Béchu on Monday night, as he referred to as on authorities of France’s seven main river basins to situation restriction orders “as of now” to anticipate a summer season drought.
Whether or not in agriculture, business or home use, “sobriety” and “saving water” are the present watchwords being utilized by the French authorities. FRANCE 24 determined to take inventory of how water is used and consumed throughout the nation.

Round 31 billion cubic metres of recent water extracted yearly
Yearly, France extracts round 31 billion cubic metres of recent water from its rivers and groundwater sources, in line with the Ministry of Ecological Transition. Subsequent to the 208 billion cubic metres of water accessible on common, this will likely not seem to be a lot. However with a purpose to preserve a balanced ecosystem, it’s important for many water to remain in nature.
Add to this the truth that the renewal of water provides can differ vastly from one 12 months to the following, relying on the quantity of rainfall. In 2019 for instance, it was estimated that solely 142 billion m3 of water had been accessible, removed from the typical 208 billion. And that’s precisely what’s worrying scientists and meteorologists for the summer season of 2023. In response to French nationwide meteorological service Météo-France, 15 of the previous 18 months have seen rainfall deficits.
One other situation is that almost all water extraction takes place in the summertime, when groundwater and river ranges are already at their lowest. The French Ministry of Ecology estimates that 60% of all water consumption takes place between June and August.
So the place does all this recent water go? Whereas a few of it’s used domestically, flowing by way of our faucets and showerheads, the remaining is used for financial functions, primarily to chill (largely nuclear) energy crops.
It’s necessary to notice that water used to chill energy crops and provide water wheels comes from floor water like rivers or reservoirs, whereas water used for ingesting, agriculture or business comes from each floor water and groundwater.
Agriculture, important shopper of water
It is also necessary to contemplate that water extracted for consumption is water that won’t be returned to its pure supply after getting used. Water despatched to nuclear energy crops, nevertheless, is utilized in an open circuit and due to this fact returned to nature after it’s used. As for agriculture, water used for livestock isn’t despatched again.
Between 2008 and 2019, the typical quantity of water extracted for consumption reached 5.3 billion cubic metres per 12 months in France. And this time, agriculture took the lead as the primary shopper of water, far forward of energy plant cooling, business and ingesting water.
“In agriculture, water is usually used to irrigate crops,” explains Sami Bouarfa, a researcher on the French Nationwide Analysis Institute for Agriculture, Meals and the Surroundings (INRAE) and deputy director of the AQUA division. “Even when the share of crops that want irrigation characterize solely 6% of all cultivated land.”

And the kind of water use varies vastly from division to division. In response to the 2021 environmental report by the Ministry of Ecology, the Adour-Garonne basin in southwest France is the place most extractions for agriculture happen. The Rhône-Méditerranée basin, alternatively, makes use of water in energy crops and is essentially the most water-hungry space. As for the Seine-Normandy and Picardy basins, water extracted is especially used to supply ingesting water.
A French particular person consumes 149 litres of ingesting water day by day
In 2020, 5.5 billion cubic metres of water had been pumped from pure sources and remodeled into ingesting water. However by the top of the 12 months, solely 3.7 billion had been consumed, in line with the newest report from France’s Observatory of Public Water and Sanitation Companies (SISPEA). The discrepancy is solely attributable to leakages that happen within the pipes carrying our ingesting water from supply to faucet. SISPEA estimates that 20% of all ingesting water in France, or one in each 5 litres, is misplaced to leakages.
Asides what’s wasted, a French particular person will eat 149 litres of ingesting water per day on common, near the European common of 200 litres, however far behind the day by day consumption of an individual from the US, who consumes 600 litres on common. In international locations with inadequate water sources, day by day consumption can drop to lower than 20 litres per particular person.
In response to the Water Data Centre, round 93% of water utilized in French households is devoted to hygiene – showering, flushing the bathroom or utilizing the washer. The remaining 7% goes on meals. Automobile washing makes use of a median of 200 litres of water, showering about 50 litres and washing garments round 60 litres.
Along with home use, there may be additionally the collective use of ingesting water in faculties and hospitals.
