ABSTRACT:
The system consists of a buffer reservoir, which is filled by gravity through a recuperation line which connects domestic appliances producing grey water, like the bathtub, the shower, the washing machine, etc. A multiple concentric elements is integrated in the reservoir and a pump draws the water from the center element of the filter for forwarding to a toilet reservoir, when the latter needs to be filled. The water filter allows the successive retention of finer and finer particles, throws them through a porous top of the filter by using the hydraulic pressure inside the filter to decompose and recirculate debris in and out of the filter while reducing at the same time the accumulation of waste in the reservoir and the frequency of cleanings. The reservoir is also equipped with a line that replenishes fresh water when the amount of grey water in the reservoir is insufficient after filling the toilet reservoir at the time of sollicitation and an overflow line to evacuate the water surplus of the reservoir toward a sewer.
