ABSTRACT:
An apparatus for cleansing gray water from showers and the like and reclaiming the cleansed water for reuse comprises a receptacle and a conduit for delivering gray water to the receptacle. A sensor detects flow of gray water into the receptacle and injects cleansing agents into the flow in response to such detection. A drain conduit communicates with the upper portion of the receptacle for extracting floating contaminants from the surface of gray water therein and a valved conduit communicates with the bottom of the receptacle for selectively extracting sinking contaminates thereform. A pump is adapted to draw the resulting cleansed gray water from the receptacle and deliver it to a remote location for reuse as, for example, in flushing toilets.
