Vacuum drainage systems can offer significant savings, using approximately 80% less water compared to traditional toilets, thereby reducing the building's total water consumption. Additionally, a vacuum drainage system can operate using rainwater or recycled grey water collected from showers, baths and washbasins, eliminating the use and cost of fresh water for toilet flushing.
Working collaboratively with a client, a vacuum drainage system has been used on a prestige office project in the heart of London's financial district.
