Water has never been so lacking in our country as in this summer of 2022. And ironically, the hotter it is, the more vital it becomes.There is therefore no question of depriving yourself of drinking it to stay hydrated, especially during repeated heat waves.Anyway, drinkable water represents only a tiny part (1%) of the 148 liters consumed on average daily by each French person.But for everything else, there are many ways to reduce the bill without necessarily losing comfort.Quite the contrary.Washing, cooking, rinsing, watering, heating… Whatever use you make of it, there is always a way to reduce the flow.Of course, some small common-sense gestures will go a long way, but it is possible to go further by equipping yourself permanently with devices specially designed to save water.From one end of the house to the other, here's how to do it so you don't have to worry about dry spells.Apart from the water we drink, approximately 16% of our consumption comes from cooking.Whether we wash the dishes, the food or our hands, this still represents around thirty liters per person per day.In the foreground, dishwashing and the eternal question that accompanies it: by hand or by machine?While most dishwashers have an average consumption of 12 liters per cycle, some models manage to drastically reduce this volume thanks to short programs.Smeg's STL323DAHL, for example, offers the WaterSave function which limits the amount of water at full load to 7 L.Photo: Smart Control mixer, GroheBut the amplitude is even more glaring if we compare with the forty liters necessary to clean the same number of plates by hand.Yet here again, appropriate technology can make significant savings.First, by directly reducing the average flow (12 litres/minute on average) by approximately 40%, thanks to a foamer installed in the spout of the sink tap.Another option?Installing a mixer with two opening positions would reduce average consumption by half.Finally, a trigger (by foot pedal or infrared sensor) allows the water to be cut off as soon as it is no longer used and to limit waste as much as possible.Any last advice?Equipping pans with suitable lids limits the amount of water needed to boil food.If there is a room in the house where the margin of savings is great, it is the bathroom.Between the 12% given to laundry and the 39% used to wash ourselves, this part of the house totals more than half of our average water needs.Here again, a central question arises: choosing between the shower and the bath.If it is obvious that a shower (40 liters on average) will always consume less water than a bath (70 liters), it is however necessary to relativize this truth.First, because there are ergonomically sized bathtubs capable of limiting the volume of water to less than 50 liters per bath, such as the Varia model from Aquarine (with a capacity of 70 liters from which the volume of the submerged body).Then because it will often be more economical to half fill a bathtub to wash several children in it than to shower them one by one.Photo: Varia corner bath, 510 euros, AquarineNevertheless, the shower remains the most competitive solution, especially if it is enhanced with a few technical solutions such as Grohe's EcoJoy™ aerator which reduces the flow rate by 50% without you even noticing it.Or like a thermostatic mixer that delivers water at temperature in a fraction of a second, avoiding letting it run unnecessarily.With such precautions, it is then possible to shower pleasantly using only about fifteen liters.But there are still washbasins where a complete arsenal can reduce expenses by up to 70%: aerator, flow limiter, integrated thermostat and an infrared sensor that will prevent lazy people from wasting water when brushing their teeth.Finally, for laundry, technological progress has made it possible to halve or even triple the quantities of water needed for each cycle with appliances such as the new Bespoke model from Samsung, capable of washing at 15°C with the same efficiency as at 40.We don't think much about it, but toilets still represent around 20% of our daily water consumption.We must first distinguish the standard models with a capacity of 9 liters from those with dual controls which only use 3 or 6 liters at the most.And it's far from being a detail, especially in large families where the reliquary can be pulled dozens of times a day.At Grohe, the Triple Vortex flushing system, for example, causes a powerful but silent whirlpool of water that cleans all of the ceramic using only 5 liters in normal mode and 3 in eco mode.Photo: Sensia Arena shower toilets, GroheAnother option is their Sensia Arena shower toilets, which also save water in another way, on a planetary scale.Indeed, they avoid buying toilet paper, the production of which is particularly water-intensive.One more proof that comfort and ecology are not incompatible.Nothing is sadder than a scorching lawn or withering plants.The first to be affected by water restrictions, our gardens nevertheless represent an exceptional opportunity to significantly reduce water consumption, throughout the house.Above all, it is a question of limiting the own watering needs of this outdoor space with plants adapted to each region, protected by effective mulching that will retain humidity.And during periods of heat, we favor drip irrigation (which avoids losses by evaporation) and we turn to ecological solutions such as ollas, buried earthen pots which regulate the water supply in the ground.Photo: Garantia collector, 39.90 euros at Leroy MerlinBut on a much larger scale, we can above all install a rainwater harvester which makes it possible to collect water that literally fell from the sky during wet periods and to use it during dry periods.If the simplest option of an above-ground model (installed directly in the gutter downspout) can only store a few tens of liters to fill your watering can, buried tanks can store several thousand liters.And the rain harvested can not only be used to water the garden or wash your car, but also to supply toilet flushes or even a washing machine, as long as it is first filtered and then distributed inside via an autonomous network, strictly different from that of drinking water.All Marie Claire news, directly in your mailboxI buy by number
