US Potable Water Reuse System Costs

This submission contains a set of U.S.-specific potable reuse capital and operations and maintenance (O&M) cost data ($2020) found in published presentations and reports from engineering consulting firms, utility and water agency press releases or websites, and literature. For any unbuilt facilities, the reported costs found in technical documents are mostly engineer estimates and may be subject to change as construction proceeds. This data set contains a mix of both facility specific and total capital costs, which include conveyance infrastructure. Note that this dataset does not include detailed cost breakdowns for each of the facilities. This submission also contains the sources used to build this dataset in pdf format.

本数据集收录了一批针对美国地区的饮用水回用项目建设及运营与维护（Operations and Maintenance，O&M）成本数据（计价基准为2020年美元），相关数据来源于工程咨询公司公开发布的演示文稿与报告、水务公用事业机构及供水机构的新闻稿或官方网站，以及各类公开文献。对于尚未开工建设的设施，技术文档中记录的成本大多为工程师估算值，后续可能随施工推进发生调整。本数据集同时包含单设施专属建设成本与涵盖输送基础设施在内的总建设成本。需注意，本数据集未提供各设施的详细成本分项信息。本提交包还附带了本数据集所用数据源的PDF格式文件。
