Heathrow Airport
During the building of the new terminal at Heathrow, British Airways decided to create 100 private bathrooms for its business and first-class customers. However, conservation issues were central to the planning on this project.
The Evac vacuum toilet with its 1.2 litre flush was the obvious choice for water conservation. In addition to this, the constraints of the building meant that no drainage pipes were able to enter the floors below. The answer was a vacuum drainage system which allowed maximum flexibility of layout but contained all of the pipework within the BA domain and had no floor penetration.
The complete system consists of over 200 Evac vacuum toilets and interface units.
