California Drinking Water System Area Boundaries (SABL)

In order to provide an accurate data set of service area boundaries for California drinking water systems, the Division of Drinking Water of the California Water Resources Control Board (SWRCB DDW) has undertaken a project to vet and verify the data collected by the Tracking California's Water Boundary Tool (WBT). SWRCB DDW downloaded a copy of the current water system service areas loaded in the WBT as of June 27, 2019. Additional attribute fields indicating verification status, verification staff and system type were appended to the data set. SWRCB DDW staff are reviewing and validating the displayed boundaries of each service area as well as contacting the service providers regarding necessary corrections. The verification status of any particular service area may be found in the Verification Status field. For any questions regarding this dataset, please contact the Data Support Unit at [e-mail].为向加利福尼亚州饮用水系统提供精准的服务区边界数据集，加利福尼亚州水资源控制委员会饮用水分部（Division of Drinking Water of the California Water Resources Control Board，SWRCB DDW）启动了一项专项项目，对加州水边界追踪工具（Tracking California's Water Boundary Tool，WBT）所采集的数据开展审核与验证工作。该分部于2019年6月27日下载了截至当日加载于WBT中的最新饮用水系统服务区边界数据。随后，项目组为该数据集追加了三类附加属性字段，分别用于标识审核状态、审核人员及系统类型。目前，SWRCB DDW工作人员正对各服务区的展示边界进行审查与核验，并就必要的修正事宜联络相关服务供应商。用户可通过「审核状态（Verification Status）」字段查询任意指定服务区的审核状态。若对本数据集存有任何疑问，请发送邮件至[e-mail]联系数据支持部门。
