The invention relates to a plant for the partial recycling of waste domestic water resulting after the use of water in household activities within multistorey buildings, depending on the building configuration and the existing installations. According to the invention, the plant comprises a storage and pumping system (1, 2, 3, 4, R, RD, 5, 6, 7, 8, 9), while preserving the original components of an initial installation (10', 11', 12', 13') and a parallel recycling and storage system based on the gravitation principle of free circulation of water taken from the kitchens sewage column (CB) upstream the blinds (BP) corresponding to the ground floor and upper floor branches, which, after passing the valves that offer the possibility to isolate the recycling circuits corresponding to the ground floor (RRP) and upper floor (RR1), is passed through the filters (FP and F1) positioned before the storage for the ground floor and upper floor, respectively, which are capable to retain the impurities and to stop the development of bacterial colony forming units during the rest periods of the installations through which the water reaches, as a consequence of the level difference, the recycling tanks (VRP and VR1) at the ground floor and upper floor, respectively, in which water is accumulated at a level higher than the toilet flushing tanks (RT), to finally reach the components of the parallel system (16, 16', 17, 17', RT, VT) and, after being reused, reaches the toilet sewage (CT). |
