本文讨论了圣地亚哥县水务局目前正在编制的区域水设施总体规划（Plan），该规划将制定设施选项和建议，以满足圣地亚哥地区到2030年的预计用水需求。该计划的一个要素是分析在该县最大限度地利用回收水的潜力。对该县当前和拟议的水资源回收计划的审查表明，再生水资源和市场的地理位置不平衡。此外，从正在进行的水设施总体规划工作来看，随着新设施投入使用，管理局进口的输水系统的某些部分可能会用于其他用途（即循环水输送）。管理局开展了一项研究，确定了循环水系统的替代方案或策略，这些替代方案或策略可能会利用管理局和/或当地机构的设施，在圣地亚哥县的循环水供应和需求之间提供平衡。 研究中制定的备选方案被视为战略，并被描述为“项目构建块”，将用于形成并建立符合项目目标的区域体系。聘请了一组顾问，协助管理局工作人员制定、分析和评估这些战略。这项研究利用了美国填海局南加州综合水回收和再利用研究（SCCWRRS）收集的数据。此外，还成立了由当地机构代表组成的咨询委员会，为研究小组制定和审查系统战略提供指导和支持。该研究确定了区域体系的优点，并建议对区域体系进行进一步详细分析。该研究确定了全县范围内的区域性改善措施，可使再生水的利用率提高4.9万英亩以上- 每年1英尺。包括桌子。

This paper discusses a Regional Water Facilities Master Plan (Plan) currently being prepared by the San Diego County Water Authority that will develop facility options and recommendations to meet the San Diego region's projected water demands through 2030. One of the elements of the Plan is an analysis of the potential to maximize beneficial reuse of recycled water in the County. A review of the current and proposed water reclamation programs in the County indicates that there is an imbalance in the geographic location of recycled water sources and markets. In addition, it is becoming apparent from the on-going water facilities master planning effort that some portions of the Authority's imported water conveyance system may become available for other uses (i.e. recycled water conveyance) as new facilities are put into service. The Authority embarked on a study that identifies recycled water system alternatives, or strategies, that potentially utilize Authority and/or local agency facilities to provide a balance between the recycled water supply and demand in San Diego County. Alternatives developed in the study are viewed as strategies and are described as "project building blocks" that will be used to form and build upon a regional system that meets the project objectives. A team of consultants was hired to assist the Authority staff in developing, analyzing and evaluating these strategies. The study utilizes data collected as part of the U.S. Bureau of Reclamation's Southern California Comprehensive Water Reclamation and Reuse Study (SCCWRRS). In addition, advisory committees consisting of local agency representatives were formed to provide guidance and support to the study team in the development and review of system strategies. The study has determined that a regional system has merit and recommended a regional system for further detailed analysis. The study has identified regional improvements throughout the county that can result in the increased utilization of recycled water by over 49,000 acre-feet-per-year. Includes tables.
