How much water do household appliances consume?
[Article updated August 5 at 13:30 with comments from France’s ecological transition minister.]
France is currently facing a drought crisis, with nearly every department introducing some sort of water restriction rules.
The Minister for Ecological Transition, Christophe Béchu, said today that more than 100 municipalities are now without drinking water and must depend on deliveries by truck.
“We have a certain number of municipalities where we have concerns in terms of drinking water. We are already at more than a hundred municipalities in France which today no longer have drinking water and to ask there are supplies by truck”, announces the Minister pic.twitter.com/31L5iNRITm

He added: “We’re going to have to get used to episodes like this. Adapting is not an option, it’s an obligation, there’s no doubt about that.”
In the Var, in the south of France, the authorities of nine municipalities have gone further by introducing a daily limit on water consumption of between 150 and 200 liters per person.
The decision was taken last week by the town halls of all the municipalities called the Pays de Fayence, made up of the municipalities:

The average person in France uses around 149 liters of fresh water per day, according to a 2020 study by the Observatory of Public Water Services.
But the town hall in Fayence, one of the towns where a limit is in place, admitted to being inundated with calls from residents asking what exactly 200 liters of water use looks like.
Mayor Bernard Henry posted a statement on Facebook on July 27 saying the commune would crack down on people exceeding the 200-litre limit.
Those who break the rules risk a fine of €1,500, which can reach €3,000 in the event of a repeat offence.
“We are going to intensify the checks [people’s] daily or weekly [water] consumption by targeted or random meter readings and we will enforce the law and fine it to its fullest extent,” he wrote.
He said people caught breaking the limit might have a ‘tablet‘ installed in their homes, which is a type of filter that can reduce the flow of water.
The town hall of Bagnols-en-Forêt has instead turned to Facebook to try to give people an idea of the water consumption of each household appliance.
They’ve also added a link to an online tool that allows you to approximate your annual water consumption, which you can see here.
