PNCC Sewer Catchment

This polygon layer defines the geographic boundaries of sewer catchments within the city. Each polygon represents an area where wastewater is collected from residential, commercial, and industrial properties and directed into the wastewater network for treatment. These catchments help the Council manage the capacity, flow direction, and infrastructure planning of the wastewater system. They are also used for maintenance scheduling, system modelling, and long-term infrastructure development. Notes: The "Updated" date you see on this item indicates when the metadata was last revised. It doesn’t necessarily reflect when the data inside the feature layer was last refreshed. The data available for download on Palmy GeoHUB is updated daily, this results in a difference between what’s currently visible online and PNCC’s databases.

本多边形图层划定了城市内污水汇水区（sewer catchments）的地理边界。每个多边形对应一个汇水区域，该区域内住宅、商业及工业场所产生的污水将被收集，并接入污水管网进行集中处理。此类汇水区可协助市政委员会开展污水系统的容量管控、流向管理及基础设施规划工作，同时也可用于维护排期制定、系统建模与长期基础设施建设规划。备注：本数据项中显示的“更新日期”仅代表元数据（metadata）的最后修订时间，并非要素图层（feature layer）内数据的最后刷新时间。Palmy GeoHUB平台上可供下载的数据每日更新，这会导致当前在线展示的数据与PNCC数据库中的数据存在差异。
