Ww Pipe (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.

污水管道（WwPipe）是承载污水管网核心功能的输送载体。污水管网的核心职能是将各类场所产生的污水输送至污水处理厂进行处理与处置。污水在管网内的输送可通过重力自流、泵压推送或真空抽吸三种方式实现。污水管道（WwPipe）同时涵盖通气管、溢流管等辅助管道设施——此类设施虽未必用于输送污水，但属于管网的连接组成部分。与仅服务单个场所的污水支管不同，污水管道通常服务多个场所（例如整条街道）。其在空间上被抽象为线状要素，是污水管网的边元素。符合IDS标准的WwPipe数据将通过WwPipeStage表进行录入。当记录被删除或编辑时，系统将执行归档操作：针对单条记录，在当日首次对其进行编辑前，该记录的编辑前快照将立即被推送至归档表。WwPipe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
