Innovative products | W+W All water entering the basin of the W+W passes through an exclusive drainage system. Due to the special filtration system, particle debris is separated out from the waste water, allowing only the liquid to pass directly into a small treatment tank where it is purified. Each flush is made directly from this tank, which is connected to the WC cistern. In this way, the water supplied is clean and hygienic. Thanks to Roca’s revolutionary ‘water reuse technology’ every last drop of this discarded water can now be saved and used again.
