Abstract
Abstract A vacuum-type water removal system for buildings, factories, ships and the like is provided wherein waste water collection devices, such as sanitary facilities (e.g., toilets) and other waste producing/or collecting devices, are connected through a cut-off valve to a vacuum conduit for removal of the waste water. The invention concerns the provision of a supplemental arrangement including an overflow opening for the collection devices which is connected to a gravity feed line that feeds a collection chamber connected through a check valve to the vacuum line.
