Ww Pump (OpenData)

WwPump represents a point in the Wastewater network where a mechanical device creates pressure to direct fluid along a pipe. The Wastewater network conveys sewage from properties to treatment plants for treatment and disposal. Wastewater is transported through the network either by gravity, by pressure from a pump, or by a vacuum. It is spatially abstracted to a point, and is a node on the Wastewater network. IDS-compliant WwPump data will be inserted via the WwPump Stage 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. WwPump assets are represented in SAP as equipment objects. Entity type: Thing.

WwPump为污水管网中的一类点位，指由机械设备产生压力以驱动流体沿管道输送的位置。污水管网负责将各类产污场所产生的污水输送至污水处理厂，以进行后续处理与最终处置。污水在管网内的输送方式可分为三类：重力自流、泵站加压以及真空抽吸。该类设施在空间维度上被抽象为一个点位，作为污水管网的节点。符合IDS规范的WwPump数据将通过WwPump Stage表进行录入。当该记录被删除或修改时，将被归档；针对该记录的当日首次编辑操作前，其要素记录的快照将被提前推送至归档表。WwPump资产在SAP系统中以设备对象的形式进行表征。实体类型：Thing。投影坐标系：新西兰横墨卡托投影（NZTM）——EPSG代码2193。垂直基准面：2016年新西兰垂直基准面（NZVD2016）——EPSG代码7839
