Abstract: A toilet system includes a water storage tank that stores fresh water used in the flush cycle. The water storage tank is divided into two compartments by a partition wall, and an air evacuating system is located in one of the compartments, while a flush control system and flush water are located in the other compartment. The air evacuating system includes a blower connected to an air passage way located in the toilet bowl and to the waste water disposal conduit. Air from inside the toilet bowl is moved to the waste water disposal conduit.
