Title: System and method for grease containment with water draining utility

Abstract: A drain connector may be arranged within a trough or sump of a grease containment apparatus to separate a water component from brown water, and automatically drain same when the brown water attains a predefined level, to prevent overflowing of brown water from the grease containment apparatus. A grease containment apparatus arranged to receive grease discharged by a fan-type rooftop grease exhauster may include multiple corner sections and at least one trough disposed between the sumps, and arranged on at least one (preferably all) sides of a rooftop grease exhauster. Mounting brackets with multiple bends may flexibly support a grease containment apparatus above a roof surface. Flashing is provided to direct grease into at least one trough section. A venturi cleaning attachment may be provided to promote forced suction discharge of a grease containment system motivated by ingress of pressurized fluid.
