Abstract

A collection apparatus for the collection and disposal of effluent from multiple sinks is provided that effectively maintains air gap and sanitation requirements within a minimal vertical distance. The preferred embodiment of present invention has multiple sinks with downwardly disposed drains and a trough mounted to collect the effluent flow from the drains. The trough has a discharge end, an overflow end, and a generally rounded bottom extending beneath the sinks and upwardly open to effluent discharging from the drains. The trough is mounted to induce effluent flow to the discharge end of the trough. The effluent flows from the sink drain through flow diverters located on the drains toward the discharge end of the trough through an air gap and into the trough. The air gap is provided between the lower end of the flow diverter and the bottom of the trough. The effluent is discharged from the trough through the discharge end into a grease separator. If the effluent flow path becomes obstructed, the effluent is discharged through the overflow end of the trough and is not able to backflow into the sink.
