The dual toilet tank system is toilet flushing system that efficiently uses the water in the tank depending on the waste being flushed. The tank body has a divider separating the tank into two compartments, one compartment has a smaller volume than the other; a flushing valve assembly with two flapper valves, one flapper valve disposed vertically higher than the other with each disposed in respective compartments; and independently operated actuators that flush the water in respective compartments or all of the tank. The smaller volume compartment is mostly used for liquid wastes while the larger volume compartment is used for solid wastes. For larger loads, both compartments are utilized.

I claim: 1. 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. 2. The dual toilet tank system according to claim 1, wherein the refilling assembly comprises: an inflow tube having one end connected to a fluid source; a fluid flow control assembly disposed on the other end of the inflow tube; and a refill tube extending from said fluid flow control assembly. 3. The dual toilet tank system according to claim 2, wherein the fluid flow control assembly comprises: an inflow valve; an elongated float arm pivotably connected to the inflow valve; and a float disposed on the float arm, wherein draining and refilling fluid in the tank lowers and raises the float to thereby respectively open and close the inflow valve. 4. The dual toilet tank system according to claim 3, further comprising a filter tube adjacent said inflow tube. 5. The dual toilet tank system according to claim 2, further comprising a filter tube adjacent said inflow tube. 6. The dual toilet tank system according to claim 1, wherein the divider further has at least one hole formed therethrough, the at least one hole being disposed above said open slot. 7. The dual toilet tank system according to claim 1, wherein the divider has at least one opening formed therethrough. 8. The dual toilet tank system according to claim 7, wherein the at least one opening includes a slot for placement of the divider between the first and second flapper valves. 9. The dual toilet tank system according to claim 7, wherein the at least one opening includes a hole for providing fluid flow and communication between the first and second compartments. 10. The dual toilet tank system according to claim 1 wherein the first flapper valve is disposed in the first compartment and the second flapper valve is disposed in the second compartment. 11. The dual toilet tank system according to claim 10, wherein the flushing valve assembly further comprises: an elongated overflow tube containing the inlet end of said flushing valve, the inlet end being operably connected to the refilling assembly, said first flapper valve extending laterally and perpendicularly from a longitudinal axis of the overflow tube at one side thereof, said second flapper valve extending laterally, opposite from said first flapper valve, and perpendicularly from the longitudinal axis of the overflow tube at the other side of the overflow tube; and a connector disposed between the first flapper valve and the overflow tube. 12. The dual toilet tank system according to claim 11, wherein said overflow tube has a connecting bore formed therethrough adjacent the bottom of the overflow tube and above the extension of the second flapper valve, said first flapper valve having a connecting bore formed therethrough, said connector fastening the overflow tube to the first flapper valve. 13. The dual toilet tank system according to claim 12 wherein the first flapper valve further comprises: a first flapper valve housing having an open end and a closed end; a cap defining the closed end of the first flapper housing; a substantially L-shaped tube extending from said first flapper valve housing, said connecting bore for the first flapper valve being disposed at the juncture of the L-shape of the L-shaped tube; and a pivotable first flapper disposed on the open end of the first valve housing to selectively open and close the first flapper valve to thereby allow draining and filling of said first compartment. 14. The dual toilet tank system according to claim 13, wherein the second flapper valve further comprises: a second flapper valve housing having an open end and an outlet shaft, said outlet shaft defining the outlet end of the flushing valve assembly; and a pivotable second flapper disposed on the open end of the second valve housing to selectively open and close the second flapper valve to thereby allow draining and filling of said second compartment, said outlet shaft being configured for mounting to a discharge passage of a toilet bowl, whereby fluid drained from either compartments flows out said outlet shaft. 15. The dual toilet tank system according to claim 1, wherein said first actuator further comprises: a first handle adjacent the first compartment; an elongated first lever arm extending from said first handle; and an adjustable chain with one end connected to a distal end of said first lever arm and the other end connected to the first flapper valve; said second actuator further comprising: a second handle adjacent the second compartment; an elongated second lever arm extending from said second handle; and an adjustable chain with one end connected to a distal end of said second lever arm and the other end connected to the second flapper valve.
