Performance assessment and benchmarking of water supply systems: one water approach

现代城市供水系统（UWS）包括三个系统，提供饮用水，废水和雨水服务，以确保高质量的生活。虽然UWS是相互关联的，但它们已经作为单独的系统进行了发展和管理。在Okanagan Valley（加拿大不列颠哥伦比亚省），大多数UWS都是中小型的，这些系统一直面临着多方面的挑战，如人口快速增长，基础设施老化和气候变化。拟议的研究旨在开发一个性能评估和基准策略，使用“一水的方法”（OWA），持续监测和改善的UWS在奥卡诺根谷。七个水资源利益攸关方：基洛纳市、西基洛纳市、弗农市、北奥肯纳根地区、皮奇兰区、湖区区和奥肯纳根盆地水委员会直接参与了这项研究。拟议项目将包括以下四个相互关联的阶段：（1）调查城市水管理的最新做法;（2）确定和制定绩效指标;（3）制定绩效评估和基准框架;以及（4）开发用于信息分析、共享拟议研究的结果将确定需要进一步改进的表现不佳的领域，并将建议在各级决策层采取干预措施。拟议的框架是可扩展的和可推广的，可以用于加拿大和全球其他司法管辖区。项目研究者（Rehan Sadiq博士）和共同研究者（Kasun Hewage博士）目前是不列颠哥伦比亚省大学的教授，两人都是各自领域的领导者。Sadiq博士和Hewage博士在供水、基础设施管理、环境风险分析、项目管理和生命周期思维领域拥有30多年的研究和行业经验。该项目将教育和培训许多具有多学科知识、技能和经验的高素质人员。该项目产生的独特知识将有助于加拿大成为水管理部门的全球领导者。

Modern urban water systems (UWSs) include three systems, which provide drinking water, wastewater, and stormwater services to ensure high quality of life. Though interconnected, UWSs have been evolved and managed as individual systems. In the Okanagan Valley (BC, Canada), a majority of UWSs are small to medium-sized, and these systems have been facing multidimensional challenges, such as rapid population growth, aging infrastructure, and climate change. The proposed research aims to develop a performance assessment and benchmarking strategy using 'one-water approach' (OWA), for continuously monitoring and improvement of UWSs in the Okanagan Valley. Seven water stakeholders: City of Kelowna, City of West Kelowna, City of Vernon, Regional District of North Okanagan, District of Peachland, District of Lake Country, and Okanagan Basin Water Board are directly involved in this research. Proposed project will involve following four interlinked phases: (1) investigation of the state-of-the-art practices in urban water management; (2) identification and development of performance indicators; (3) development of the performance assessment and benchmarking framework; and (4) development of web portal for information analysis, sharing, and learning.The results from the proposed research will identify underperforming areas requiring further improvement and will recommend interventions at various decision making levels. The proposed framework is scalable and generalizable, which can be employed to other jurisdictions in Canada and globally. The project investigator (Dr. Rehan Sadiq) and co-investigator (Dr. Kasun Hewage) are currently professors at the University of British Columbia and both are leaders in their field. Drs. Sadiq and Hewage jointly hold research and industry experience of over 30 years in the area of water supply, infrastructure management, environmental risk analysis, project management, and life cycle thinking. This project will educate and train numerous highly qualified personnel with multidisciplinary knowledge, skills, and experience. The unique knowledge generated from this project will help Canada to be a global leader in the water management sector.
