Vacuum sanitation technology offers two major advantages: Firstly installations produce large savings in water use technology and secondly, thanks to the flexibility of the pipe layout, they provide architects and builders greater freedom in the planning of buildings.

Saving Water
RoeVac^® vacuum toilets require only one litre of water per flush compared with conventional toilets that use between 6 and 10 litres per flush, saving significant quantities of water.

The volume of water required for urinals can also be reduced considerably and wash hand-basins can be fitted with tap aerators. Vacuum sanitation technology is therefore used in buildings and at locations where large savings in water use are either required or can be generated.

Ideal developments for vacuum installations are where there is a high density of sanitary fittings required with the potential for large savings in water use.

Flexible Construction
Internal vacuum sanitation systems offer great flexibility during both planning and installation. Main lines may be installed between suspended floors and ceilings giving the possibility of connecting sanitary fittings from above and from lower levels. Pipelines do not need to be laid to a slope and are independent of natural falls.

In addition to new buildings, ideal applications for vacuum technology are where the sanitation systems of old buildings are to be renewed.
