Ww Pipe Type (OpenData)

WwPipe represents a conduit that performs the primary function of the Wastewater network. 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. WwPipe also represents supplementary pipework such as vents or overflows that may not necessarily carry wastewater, but are otherwise connected and part of the network. Wastewater pipes generally service more than one property (e.g. a whole street), in contrast to wastewater laterals which generally only service one property. It is spatially abstracted to a line, and is an edge on the Wastewater network. IDS-compliant WwPipe data will be inserted via the WwPipeStage 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. WwPipe assets are represented in SAP as equipment objects. Entity type: Thing.WwPipe是承担污水管网（Wastewater network）核心功能的管道载体。污水管网的作用是将各类建筑产生的污水输送至污水处理厂进行处理与最终处置。污水在管网中的输送方式主要包括重力自流、泵压提升以及真空抽吸三种。WwPipe同时涵盖诸如通风管、溢流管这类辅助管道系统——此类管道虽未必直接输送污水，但均属于管网的组成部分且与管网相连。与仅服务单处建筑的污水支管（wastewater laterals）不同，WwPipe通常服务于多栋建筑（例如整条街道）。该类要素在空间上被抽象为线状几何，作为污水管网中的边（edge）存在。符合IDS标准的WwPipe数据将通过WwPipeStage表进行录入。当数据记录被删除或编辑时，对应条目将被归档；在该记录当日首次编辑前，其编辑前的要素快照将被即刻写入归档表。WwPipe资产在SAP系统中以设备对象的形式进行表征，其实体类型为Thing。
