Ws Valve (OpenData)

WsValve represents a device to control the flow of fluid in the WaterSupply network. The Water Supply network is a pressurised system that distributes potable or non-potable water to properties for the purposes of consumption, irrigation and firefighting. It is spatially abstracted to a point, and is a node on the WaterSupply network. IDS-compliant WsValve data will be inserted via the WsValveStage 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. WsValve assets are represented in SAP as equipment objects. Entity type: Thing.
