Toilet water supply system
TLDR
In this paper, a filtration unit is used to remove large particles for the waste water and the filtered water passes into a storage tank which holds the water until needed, and then the water is drawn by a pump and delivered to a device which will scent and colour the water prior to entry into a conventional toilet cistern.Abstract:
A toilet water supply system which replaces the existing mains water supply to the toilet cistern with domestic recoverable waste water resulting in overall reduction of domestic consumption and more efficient use of pure water. This is achieved by collecting waste water from recoverable sources through pipework (1) to a filtration unit (2), which removes large particles for the waste water. A facility is provided with the filtration unit (2) to enable the filter to be cleaned. The filtered water passes into a storage tank (3) which holds the water until needed. From the tank (2) the water is drawn by a pump (5) controlled by pressure switch (6) assisted by an accumulator (7) and delivered to a device (8) which will scent and colour the water prior to entry into a conventional toilet cistern.read more
