The WC’ represents our biggest consumption of drinking water (1/3 of our total consumption). In average, only one flush uses 9 Lt. of water (sometimes it uses until 18 Lt. for the old systems!). Knowing that, in average one person goes 4 times to the toilet per day, this represents 36 Lt./day/person!
In France, a total of 100 milliards of liters of drinking water are used in the toilets.
To reduce this waste, many solutions are possible: to re-using rain water in the toilets, the sinks placed over the flush control, composting toilets, following its water consumption for supervising the leaks, anda…
It’s agile to adapt the water flow to the needed function. Also, the little bottom just uses 3 Lt. and the big one uses the maximum of 6.
This allows to reduce at least the half of the water waste, and so do the bill!
There’s no need to change the toilet tank, it’s enough with changing the mechanism (caution: nevertheless all the mechanisms don’t adapt themselves to all the toilet tanks).
