Ww Vacuum Breather Pipe (OpenData)

WwVacuumBreatherPipe represents a conduit that carries air from a Vacuum Breather to a Vacuum Chamber, to maintain the correct air-to-liquid ratio within the vacuum pipes of the Wastewater network. The Wastewater network conveys sewage from properties to treatment plants for treatment and disposal. It is spatially abstracted to a line, and is an edge on the Wastewater network. IDS-compliant WwVacuumBreatherPipe data will be inserted via the WwVacuumBreatherPipeStage table. When deleted or edited, the record is Archived. A snapshot of the feature record, before it is edited, will be sent to the archive table immediately prior to the first edit of the day for that record. WwVacuumBreatherPipe assets are represented in SAP as equipment objects, located under a functional location derived from its corresponding WwVacuumSite. Entity type: Thing.
