Gutter liquid separator

A gutter liquid separator is shown for separating liquid from non-liquid debris and for removing debris from a rain water gutter system secured to a roof of a structure. In a particular embodiment, the gutter liquid separator includes two main components; a debris discharge outlet and a liquid separator. The debris discharge outlet includes a flow surface, an inner and an outer wall extending up from the flow surface so that upstream edges of the flow surface, inner and outer walls are secured to a U-shaped gutter of the system. The debris discharge outlet also includes a debris drop-off edge that defines a drop-off plane passing through downstream edges of the flow surface, inner and outer walls. The liquid separator is secured to the debris discharge outlet and includes a liquid collection box secured to a bottom surface of the flow surface under the debris discharge outlet, and a liquid directing surface secured between the debris drop-off edge adjacent the downstream edge of the flow surface and a liquid inlet of the liquid collection box that directs liquid from the flow surface to the liquid collection box. The liquid collection box defines a liquid discharge outlet dimensioned to receive a downspout of the rain water gutter system. Liquid adheres to the liquid directing surface and flows into the liquid collection box, while debris flowing with the liquid drops off the debris drop-off edge out of the system.
