Abstract

A domestic water system comprises: units, including toilets, fed under gravity from a storage tank; a water softener (2) including a membrane (9), and first and second outlets (3, 4) for softened water and reject water, respectively and first and second storage tanks (14, 15) for softened water and reject water, respectively, the second tank (15) being in connection with the toilet (24), and the first tank (14) being in connection with other units (20). The invention makes particular use of the fact that the proportion of reject water from a membrane softener, and the proportion of domestic water usage for flushing toilets, are very similar. Water wastage is thus minimised.
