For example, water supply systems with water treatment of gray water or waste water were designed, which reuse the treated water used for the toilet systems. The consumption values of the toilet system and hand wash water become the result It is clear that 2/3 of the water used is used in the toilet system. However, the water quality requirements for the toilet system are not as high as for the hand wash water. If water is saved, the water tanks can be made smaller as less fresh water is used. If the water tanks are too large, there are problems with the water hygiene, since the water in the water tanks becomes contaminated after a few days.
