A portable toilet system is provided having an enclosed housing and including a tank upon which a toilet seat and bowl is positioned. The tank has two sections divided by a wall. Waste drops into the first section where it is accumulated for collection. The dividing wall does not extend to the top of the tank. The second section is initially filled with fresh water. A pump draws water through a hose or pipe submersed in the second section. That water is flushed into the toilet bowl to rinse waste into the first section. As the water in the second section is depleted, the liquid waste deposited in the first section overflows the dividing wall into the second section of the tank to recycle the liquid waste and extend the period before servicing of the system is necessary.
