A diagram explaining the function of a closed loop sanitation system connected to a small apartment building. When apartment occupants flush their toilet, waste moves to a settling tank, then it is processed by a reactor which converts the salts in urine into bleach, disinfecting the water. The treated water is pumped to a rooftop tank which can be reused for flushing.
