Claim:
A dual toilet tank system, comprising: a tank including a tank body, the tank body having at least opposing front and back walls and a bottom for holding a volume of fluid; a refilling assembly operably connected to the tank; a divider insertably mounted in the tank in between and touching the opposing front and back walls and the bottom, separating the tank into first and second compartments and providing fluid communication therebetween, a volume of the first compartment being substantially smaller than a volume of the second compartment; wherein the divider has an open slot disposed therethrough at the bottom of the divider so that the divider may be inserted between the first and second flapper valves and permit said fluid communication between the first and second compartments via the open slot when it is mounted in the tank; a flushing valve assembly having an inlet end and an outlet end and first and second flapper valves, the first flapper valve being disposed vertically higher than the second flapper valve with respect to the bottom of the tank; a first actuator for selectively flushing fluid in the first compartment; and a second actuator for selectively flushing fluid in the second compartment, wherein the first and second actuators are independently actuated to drain fluid from each of the compartments or the tank.
