  • Publication number: 20060237373
    Abstract: A vacuum transport system suited to moving FOG-laden water. The system includes a first reservoir and at least one vacuum pump in fluid communication with the first reservoir and operable to produce a vacuum within the first reservoir. A first accumulator is positioned to collect FOG-laden water from a first FOG-laden water source. A first valve is operable to selectively provide fluid communication between the first accumulator and the first reservoir. FOG-laden water can be drained from the first reservoir into a grease interceptor disposed in the building exterior.
