South West Water appointed water supply boundary

This dataset outlines the geographical boundaries within which South West Water provides clean water supply services. This shapefile is intended solely for geospatial analysis. The authoritative legal delineation of areas is maintained in the maps and additional details specified in the official appointments of companies as water and/or sewerage undertakers, along with any alterations to their areas. The shapefile does not encompass data on any structures or properties that, despite being outside the designated boundary, are included in the area, or those within the boundary yet excluded from the area. In terms of geospatial analysis and visual representation, the Mean High-Water Line has been utilized to define any boundary extending into the sea, though it's more probable that the actual boundary aligns with the low water mark. Furthermore, islands that are incorporated into the area might not be included in this representation.本数据集划定了西南水务（South West Water）提供洁净供水服务的地理边界。本形状文件（shapefile）仅可用于地理空间分析（geospatial analysis）。区域的法定权威界线以各供水/排污特许经营企业的正式委任文件、配套地图及附加细则为依据，其服务范围的任何变更亦需同步更新该界线。本形状文件未涵盖两类数据：一是虽处于划定边界之外，但实际被纳入服务区域的建（构）筑物或物业；二是虽处于划定边界之内，但未被纳入服务区域的建（构）筑物或物业。在地理空间分析与可视化呈现场景中，本数据集采用平均高潮线（Mean High-Water Line）作为临海边界的界定标准，但实际服务边界大概率与低潮线相符。此外，纳入服务范围的岛屿可能未在本数据集中得到体现。
