A personal water conservation system includes gray water discharge lines, a main sewage line, an impurity measuring unit, a buffer tank, a directional control valve, a water treatment unit, a treated water tank, an automatic shutoff valve, and at least one toilet flush tank. The buffer tank and the water treatment unit purify the gray water in two different stages. The purified gray water is then stored in the treated water tank. If the gray water can't be purified within the personal water conservation system, the impurity measuring unit and the directional control valve redirect the gray water into the main sewage line. The purified water from the treated water tank can be used with the at least one toilet flush tank in order to conserve fresh water.
