The Willoughby EVAC vacuum plumbing system is an engineered system using differential air pressure to transport sanitary waste water from plumbing fixtures, such as vacuum toilets, sinks and showers, through a vacuum piping network to the vacuum collection tank. The vacuum collection tank maintains operating vacuum pressure throughout the piping network and controls the collection and discharge from the system. Potential advantages include:
- Reduced construction time and cost
- Increased security and control
- Reduced maintenance cost
- Reduced water and sewage bills
