What is the water consumption of French households in 2020?

Consommation d'eau en france

Since the end of the 18th century, the consumption of water has been steadily increasing.

Nowadays, all you have to do is turn on the tap to enjoy drinking water. This water is no longer only used for drinking: washing up, showering, toilets, swimming pool, watering the garden...

It has many uses, but it is still a rare resource that must be preserved. How much drinking water did French households consume in 2020? What consumes the most water? Here are all the answers to your questions.

Average water consumption for a French household: the figures to remember

In 1975, French people consumed 106 litres of water per day. Today, it is approximately 150 litres per person per day. These figures depend of course on several criteria:

  • An adult uses more water than a child who only needs 69 litres;
  • A high standard of living leads to a higher water consumption than a modest household that uses an average of 90 litres per day;
  • An athletic person will have a higher consumption (about 240 litres of water per day) due to an increased need for hydration and repeated daily showers;
  • Climatic conditions and tourist activity influence water needs and average household consumption. For example, people in Nord-Pas-de-Calais consume an average of 109 litres per day, compared to 228 litres per day in Provence-Alpes-Côte-d'Azur;
  • Holiday periods increase our average water consumption.

Revaluing tap water with LaVie

Les purificateurs d'eau LaVie

LaVie UV-A water purifiers® operate without filters or maintenance and allow you to purify your tap water in 15 minutes.

They use an innovative, patented technology exclusive to LaVie®: the photolysis of chlorine by UV-A radiation.

This treatment allows the removal of chlorine and its derivatives, chemical compounds such as certain pesticides or traces of medication, and tastes and odours that can be found in tap water.

The result, which is very qualitative, makes it possible to draw a definitive line on the consumption of water in plastic bottles.

The carbon footprint linked to the manufacture of the aluminium tube of the UV water purifier is neutralised in a few days of use compared to the equivalent consumption of water in plastic bottles.

The different water points in a household

The main sources of water consumption are showering and cleaning: they both account for 93% of our average consumption. For the rest, it is quite difficult to quantify precisely each point of consumption, since it depends mainly on the appliances used and the habits of each person. For example, the volume of water consumed during a shower varies according to the duration, the mixer tap used or the flow rate. Some washing machines and dishwashers are also more water-efficient thanks to the "eco" programme. On average, here are all the water consumption items in a home:

  • 7% for food and drink
  • 10% for washing dishes
  • 12% for washing clothes
  • 40% for hygiene (baths and showers)
  • 20 % for sanitary facilities (count about 6 litres of water for each flush)
  • 6% for watering the garden and cleaning the outside
  • 5% for cleaning the house

Note, however, that this amount of water can increase considerably with possible leaks. A dripping faucet uses 4 litres per hour, or 35,000 litres of water per year.

For example, the volume of water consumed during a shower varies according to the duration, the mixer tap used or the flow rate.

Has water consumption decreased during containment?

The year 2020 was marked by the Coronavirus and an international containment. In France, some regions saw a 15% drop in drinking water consumption, due in part to a drop in tourist activity and closures of schools, swimming pools and businesses. Other regions, such as Île-de-France, did not experience a significant drop. This water consumption has not really varied on a national scale, except for a 5% decrease at the national level.
Furthermore, the authorities remind us that tap water can be consumed in complete safety. Indeed, there is no risk of contamination by Covid-19 since the virus and bacteria are not resistant to chlorine and various treatments. It is therefore quite normal to smell a slight chlorine taste in the water. If this bothers you, don't hesitate to use our water purifiers, the only ones that are 100% eco-responsible: no plastic waste, very low carbon cost during manufacturing, preservation of all trace elements, purified water... It is an excellent alternative to plastic bottles or filtering carafes.

How to reduce water consumption?

Thanks to a change in behaviour and new eco-citizen reflexes, drinking water consumption has been falling for several years. We must therefore continue to act on a daily basis to preserve this precious resource. To do this, a few easy steps can be taken:

  • Repair water leaks, knowing that a flush leak wastes 220,000 litres of water per year;
  • Take quick showers rather than baths to save 130 litres per shower;
  • Water your garden in the morning or evening, when temperatures are not yet too high;
  • Use a regulator on taps and a dual control toilet;
  • Renovate to replace an outdated water heater;
  • Install a rainwater harvesting system for watering the garden or cleaning the car;
  • Opting for "eco" programs for household appliances.

Finally, we must not forget electricity consumption, which is also one of the main items of expenditure for French households. If it is essential to preserve the longevity of water, it is also important to encourage the development of renewable energy. What can you do? By choosing a green energy supplier!
