Ww Flush Tank (OpenData)

WwFlushTank represents a chamber used to hold water, that is periodically filled and released to flush portions of the Wastewater network (eg Flush Tank, Flushing Syphon Chamber). The Wastewater network conveys sewage from properties to treatment plants for treatment and disposal. It is spatially abstracted to an area and is a child on the Wastewater network. IDS-compliant WwFlushTank data will be inserted via the WwFlushTankStage 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. WwFlushTank assets are represented in SAP as equipment objects. Entity type: Thing.
