A system is disclosed wherein white waters, i.e., those soapy waters coming from washing stands, showers, wash basins and the like, are carried, through receiving and filtering devices, down to the tank or container of a toilet either at the same level of the building or down to a lower level. By means of the devices employed in this invention cesspools are dispensed within sanitary devices from which white water is obtained, and also water entrance valves and floaters in toilet tanks are dispensed with. A novel flushing valve is provided in the system, whereby leaks of water from the tank into the draining system, through the overflow duct in said tank is prevented; there being provided a special overflow tube through which the water in excess from a level in a building can be used in another lower level and so down to a cistern or the like wherein the excess water of the system is stored and from which said water is pumped up to a deposit or the like, from which said water is recirculated through every level of said building passing through every tank of said toilets.
