Vacuum drainage system for toilet

摘要

Identical or closely similar types of effluent from different entry points are conveyed at equal times and at effluent consistency-dependent intervals over a single shared network of offtake lines. The system outputs vary by as many grades of effluent at these same intervals. Effluents concerned are respectively toilet soil water or domestic waste water or trade effluent or their combinations. The vacuum in the drainage network laid underfloor outside the building is also used to convey water inside the building, preferably to drain vacuum toilets. Separate entries to the drainage system ensure all toilets in any one building are drained by a shared vacuum layout. Thus a single underfloor system such as a public mains also takes the toilet effluent from private buildings.
