1214122 (Mosher). Direct Potable Reuse (DPR) is the planned introduction of recycled water directly into a public water system or into a raw water supply upstream of a water treatment plant. DPR has the potential to provide a reliable, sustainable local water supply; however, it is not easily implementable in the U.S. due to scientific/technical knowledge gaps and public perception. This multi-disciplinary workshop will bring together academics and water professionals to focus on the technical and social challenges and either directly address them or prepare guidance on means to address them. The workshop will include review of background papers, working group sessions, group report development, and presentations of group reports. A final report will be accessible online. The workshop will advance knowledge in public perception (social science) and technical issues (engineering). The public perception outcomes will directly enhance outreach and educational activities in the water industry. The technology outcomes will enhance scientific research and engineering applications by identifying key issues that will allow for the implementation of DPR and improve current water treatment technologies. DPR has the potential to significantly improve and diversify sustainable water resources management throughout the US, especially in arid regions like CA, AZ, and TX. It can reduce the need for long-distance water conveyance (and associated energy consumption). DPR implementation can also encourage the transformative view that wastewater is a renewable recoverable source of energy, nutrients, and potable water. The final product, a workshop report, will provide guidance on developing protocols for addressing technical challenges to DPR (e.g., modifications needed to upgrade existing advanced treatment facilities to DPR). It will also provide outreach/education tools to better communicate and increase the public?s understanding of DPR. The workshop report will be disseminated broadly to the water community as a free internet download for the purpose of enhancing the scientific and technical understanding of methods/facilities needed to undertake DPR projects, as well as enhance the understanding of social aspects/activities needed to gain public acceptance of DPR. The workshop has the potential to help make DPR a viable option for communities seeking to augment/diversify potable water supplies. Some benefits of DPR to society at-large include: providing a water supply alternative for communities that lack groundwater aquifers or surface water; reducing wastewater discharge to the ocean or inland surface waters, reducing the extraction/depletion of water from aquifers and surface waters, and reducing energy use.

1214122（莫舍）。 直接饮用水再利用（DPR）是计划将回收水直接引入公共供水系统或水处理厂上游的原水供应。DPR有可能提供可靠的，可持续的当地供水;然而，由于科学/技术知识差距和公众认知，它在美国并不容易实施。这一多学科研讨会将汇集学术界和水资源专业人员，重点关注技术和社会挑战，并直接解决这些挑战或编写关于解决这些挑战的方法的指导。讲习班将包括审查背景文件、工作组会议、编写小组报告和介绍小组报告。最后报告将在网上提供。讲习班将增进公众认知（社会科学）和技术问题（工程）方面的知识。公众认知结果将直接加强水行业的外联和教育活动。这些技术成果将通过确定关键问题来加强科学研究和工程应用，这些关键问题将允许实施DPR并改进当前的水处理技术。 DPR有潜力显着改善和多样化可持续水资源管理在整个美国，特别是在干旱地区，如CA，AZ和TX。它可以减少长距离输水的需求（以及相关的能源消耗）。DPR的实施还可以鼓励变革性的观点，即废水是可再生的可回收能源，营养物质和饮用水。最终产品是研讨会报告，将为制定解决DPR技术挑战的协议提供指导（例如，将现有的高级处理设施升级为DPR所需的修改）。它还将提供外展/教育工具，以更好地沟通和增加公众？对DPR的理解。研讨会报告将作为免费互联网下载广泛传播给水资源社区，以提高对开展DPR项目所需方法/设施的科学和技术理解，并提高对获得公众接受DPR所需的社会方面/活动的理解。讲习班有可能帮助使DPR成为寻求增加/多样化饮用水供应的社区的可行选择。DPR对整个社会的一些好处包括：为缺乏地下蓄水层或地表水的社区提供供水替代方案;减少向海洋或内陆地表沃茨排放废水，减少从蓄水层和地表沃茨中抽取/消耗水，以及减少能源使用。
