Clean drinking water: conserving and recuperating it


EauPotable BainDoucheThe shower uses 17% of all water in the home. Fortunately, there are a wide range of possibilities to reduce our consumption. A flow switch stops the flow of water during a shower, but this is only available on some very specific showerhead models. As for thermostatic mixer taps, they avoid water wastage during a shower, but their cost is high.

For a more reasonable price, a low-cost showerhead of a maximum of 6.6 LPM is available in any hardware store: you will not notice any difference in pressure.

Look for the WaterSense certification for all your plumbing fixtures. This certifies the quality and performance of appliances and fixtures that have a reduced water consumption.


And let’s not forget the tub. While taking a bath is certainly appealing to some, you should choose, more often than not, a shower. Using the same quantity of water consumption as that of a tub full of water (on average 150 liters, 40 gallons) is equal to more than 22 minutes in the shower.

Thanks to energy-efficient appliances, the ERE 132 allows for a reduction, in one bathroom alone, of about 200 liters (53 gallons) of water per day. That’s 15,330 liters (4,050 gallons) per year!
