This Engineering Research Initiation (ERI) project will develop a novel hybrid centralized and decentralized water system (water microgrid system) to achieve both water supply sustainability and resilience. Current centralized water infrastructure faces enormous challenges from climate change, extreme drought, population growth, aging infrastructure, and energy security. Such challenges require a transformation of current water systems to be more sustainable and resilient. This project establishes benchmark models of a water microgrid system, which features decentralized water supply systems with local water sources nested within existing centralized systems. The water microgrid system will increase water use efficiency and conservation through water recycling and harvesting for distributed water sources. Furthermore, the system can change its operations between centralized and decentralized water supply against unexpected disruptions and thus will enhance system resilience. The project outcomes will advance scientific progress and contribute to national welfare and water services by suggesting engineering solutions to upgrade current water infrastructures to make them more sustainable and resilient. The project team will conduct integrated education and outreach activities through water forms, a project website, publications, course development, international partnership, and other outreach programs for the public and K-12 students. This project will encourage the participation of students from underrepresented groups in research activities. This project aims to advance the understanding of a hybrid microgrid approach for water systems and its sustainability and resilience outcomes. The project will contribute to knowledge on how to incorporate decentralized infrastructure in tandem with current centralized water systems for water supply sustainability and resilience. The project tasks include (1) building a lab-scale physical model of a water microgrid system; (2) testing the configuration and operations of a water microgrid system using a hydraulic model; (3) developing a framework to sectorize an existing water supply system into microgrids; and (4) evaluating the sustainability and resilience effects of water microgrid systems based on system size, decentralization levels, and failure scales. The project outcomes will provide insights and guidance to facilitate a transition from current urban water infrastructure to new ways of simultaneously improving water sustainability and system resilience. These outcomes will also lead to new planning, design, and tools for urban lifeline infrastructure to effectively incorporate microgrid and decentralized infrastructure.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这一工程研究启动(ERI)项目将开发一种新型的集中式和分散式混合供水系统(水微电网系统)，以实现供水的可持续性和弹性。目前的集中式水利基础设施面临着来自气候变化、极端干旱、人口增长、基础设施老化和能源安全的巨大挑战。这些挑战要求对现有的水系统进行改造，使之更具可持续性和弹性。该项目建立了水微电网系统的基准模型，该系统的特点是分散式供水系统，当地水源嵌套在现有的集中式系统中。水微电网系统将通过对分布式水源的水回收和收集来提高水的利用效率和节约用水。此外，该系统可以在集中式和分散式供水之间切换操作，以防意外中断，从而增强系统的复原力。项目成果将推动科学进步，并通过提出升级现有水利基础设施的工程解决方案来促进国家福利和水服务，使其更可持续和更具弹性。项目团队将通过水表、项目网站、出版物、课程开发、国际伙伴关系和其他面向公众和K-12学生的外联计划，开展综合教育和外联活动。该项目将鼓励来自代表性不足群体的学生参与研究活动。该项目旨在促进对水系统混合微电网方法及其可持续性和复原力成果的理解。该项目将有助于了解如何将分散的基础设施与现有的集中式供水系统结合起来，以实现供水的可持续性和复原力。该项目的任务包括(1)建立水微电网系统的实验室规模的物理模型；(2)使用水力模型测试水微电网系统的配置和运行；(3)开发将现有供水系统划分为微电网的框架；以及(4)基于系统规模、分散程度和故障规模来评估水微电网系统的可持续性和复原力影响。项目成果将提供洞察力和指导，以促进从目前的城市水基础设施向同时提高水可持续性和系统复原力的新方法的过渡。这些成果还将为城市生命线基础设施带来新的规划、设计和工具，以有效地整合微电网和分散的基础设施。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
