PI name: Kevin LanseyInstitution: University of ArizonaProposal Number: 0835930This award is an outcome of the competition as part of the Emerging Frontiers in Research and Innovation (NSF 07-579) solicitation under the subtopic Resilient and Sustainable Infrastructures (RESIN). The proposed project will advance engineering and scientific understanding and will develop new methods for integrated water and wastewater infrastructure planning. Over the next four years, the project aims to identify, design and evaluate water supply/wastewater treatment system configuration alternatives in the presence of complex, competing objectives and uncertainty. Each configuration will include all major conveyance facilities (pumps and pipes), storage, and treatment facilities for water and wastewater. Alternative facilities plans will be evaluated based on the triple bottom lines consisting of: (i) economic, (ii) environmental, and (iii) social values. The major intellectual innovation is the proposed approach to optimize a sustainability objective function that embodies the triple bottom line with components representing capital, operation, and maintenance costs; greenhouse emissions and depletion of ecosystem water allocations; social and institutional defined limits on water reuse and decentralized wastewater treatment; and risk as penalties arising from failure to meet system sustainability and resilience objectives. In addition to the innovations in the encompassing effort, novel approaches will be developed for dual water distribution system planning and design and new computational algorithms will be developed to optimize the resulting models. Frameworks for assessing social and institutional preferences, in the short-term for existing infrastructure and reuse options and in the long-term as co-evolving with conjunctive systems will be established.Multiple factors combine to increase the complexity and urgency of water/wastewater facilities planning, as addressed by this project: (i) water scarcity and the need for efficient and sustainable use of every available water resource; (ii) increased population and thus, increased demand for water; (iii) general deterioration of water supply and sanitary infrastructures that are reaching the end of their lifecycles; (iv) heightened public awareness of the quality of water consumed; (iv) interdependence of water supply goals and other, sometimes competing objectives such as in-stream uses for reclaimed water and minimization of greenhouse gas emissions. These factors necessitate an urgent consideration of infrastructure system sustainability and resilience in the presence of supply and demand uncertainties. In short, water supply based solely on engineering judgment must be transformed to operate in an increasingly complex planning landscape. Moreover, the proposed research directly addresses the recently identified "National Academy of Engineering Grand Challenge" of restoring and improving urban infrastructure and wastewater systems. The systems analytical tool will generate impact, not only in the southern Arizona growth corridor but also nationally as a result of its generic approach. It will allow planners to objectively approach decisions regarding sustainable water/wastewater systems integration, degree of decentralization of new wastewater treatment facilities, timing and scale of new facility addition, and (where system extension is contemplated) apportionment of costs among existing and proposed facilities. The application of the tools to real systems and generating guidance for the applicability of decentralized dual water supply system will lead to the much broader impact of altering the present water supply paradigm that treats wastewater as a disposal issue rather than a resource. Our approach considers an integrated water and wastewater infrastructure system that is advantageous in meeting expanding water demands while accumulating the benefits of lower energy consumption and cost, a reduced carbon footprint, and better overall water quality. The project also has significant public awareness and education activities on water reuse at many levels, including key institutions (e.g., regional players such as Tucson Water) and K-12 education. Workshops will be held at AWWARF and WERF meetings. Innovations from the work will be published in peer-reviewed journals, disseminated to practitioners, and incorporated into engineering and public policy curriculum. Efforts will be made to expand the role of under-represented groups in this area through project participation.

PI名称：Kevin Lanse机构：亚利桑那大学提案编号：0835930该奖项是作为新兴前沿研究与创新(NSF 07-579)征集活动的一部分，在副主题弹性和可持续基础设施(REST)下进行的竞赛的结果。拟议的项目将促进工程和科学理解，并将为综合水和废水基础设施规划开发新的方法。在接下来的四年里，该项目的目标是在存在复杂、相互竞争的目标和不确定性的情况下，确定、设计和评估供水/废水处理系统配置备选方案。每个配置将包括水和废水的所有主要运输设施(泵和管道)、存储和处理设施。替代设施计划将根据三重底线进行评估，这三重底线包括：(一)经济、(二)环境和(三)社会价值。主要的智力创新是拟议的优化可持续性目标功能的方法，该功能体现了三重底线，包括资本、运营和维护成本；温室气体排放和生态系统水分配的枯竭；对水的再利用和分散废水处理的社会和体制定义的限制；以及因未能实现系统可持续性和复原力目标而产生的惩罚风险。除了包罗万象的工作中的创新之外，还将开发用于双重供水系统规划和设计的新方法，并将开发新的计算算法来优化所产生的模型。将建立评估社会和体制偏好的框架，在短期内评估现有基础设施和再利用选择，并在长期内与联合系统共同演变。本项目涉及的多种因素结合在一起，增加了水/废水设施规划的复杂性和紧迫性：(1)缺水，需要有效和可持续地使用每一种可用的水资源；(2)人口增加，因此对水的需求增加；(3)供水和卫生基础设施的普遍恶化，即将结束其生命周期；(4)提高公众对用水质量的认识；(4)供水目标与其他有时相互竞争的目标相互依存，例如在河流中使用再生水和最大限度地减少温室气体排放。这些因素迫切需要考虑基础设施系统在供需不确定情况下的可持续性和复原力。简而言之，仅基于工程判断的供水必须转变为在日益复杂的规划环境中运行。此外，这项拟议的研究直接解决了最近确定的恢复和改善城市基础设施和废水系统的“国家工程院的重大挑战”。系统分析工具将产生影响，不仅在亚利桑那州南部的增长走廊，而且由于其通用方法而在全国范围内产生影响。它将使规划者能够客观地作出以下决定：可持续的水/废水系统集成、新废水处理设施的分散程度、增加新设施的时间和规模，以及(如果考虑扩展系统)在现有和拟议设施之间分摊费用。将这些工具应用于实际系统，并为分散的双重供水系统的适用性提供指导，将产生更广泛的影响，改变目前将废水视为处置问题而不是资源的供水模式。我们的方法考虑了一个集成的水和废水基础设施系统，该系统有利于满足不断增长的水需求，同时积累了更低的能源消耗和成本、减少的碳足迹和更好的整体水质。该项目还在多个层面开展了大量关于水再利用的公共宣传和教育活动，包括关键机构(例如，图森水务等区域参与者)和K-12教育。研讨会将在AWWARF和WERF会议上举行。这项工作的创新将发表在同行评议的期刊上，传播给从业人员，并纳入工程学和公共政策课程。将努力通过项目参与扩大任职人数不足群体在这一领域的作用。
