The long-term goal of my research is to develop decision support tools to continuously improve reliability and accessibility of drinking water supply. In the past 5 years, the primary focus of my NSERC-DG has been on developing risk management strategies for water supply systems (WSS) for large municipalities. However, about 95% of the WSS in Canada are categorized as small to medium-sized water utilities (SMWUs). A drinking water quality management system (DWQMS) is needed to effectively manage the critical control points in WSS and their associated hazards. This research program proposes a ‘continuous performance improvement' approach for implementing short- and long-term asset management strategies within DWQMS. The short-term objectives encompass three main themes: (1) risk identification & performance benchmarking, (2) risk assessment, and (3) risk management for continuous performance improvement.****In this research, raw data (e.g., geographical factors, water quality indicators, structural reliability, customer service, human and operational factors) will be collected from various SMWUs in NL, QC, and BC, which fully represent the inherent variability in Canadian landscape, and help in developing generalized and scalable models. In Theme 1, source to tap performance indicators for risk of 'water quality failures' will be identified and developed. This will help establish risk-based performance benchmarks and quantify overall risk of water quality failure in a WSS. In Theme 2, the impact of seasonal and geographical factors will be evaluated and a risk quantification model will be developed using bow-tie analysis. This will lead to identification of appropriate interventions and determine ‘residual risk' under different operating conditions. In Theme 3, the lifecycle benefit-cost analysis will be performed to determine residual risk, cost and environmental impacts for the selected interventions over their lifecycle. Multi-objective optimization will highlight ‘best' risk management strategy as a combination of interventions at critical control points in a WSS. This will drive best management practices and policy guidelines to build comprehensive water safety plans which guarantees continuous performance improvement of SMWUs.****In the short-term, the benchmarks are established to comply with existing regulatory requirements but more stringent benchmarks (e.g., international health guidelines, benchmarks for large municipalities) will be set in the future years. In the long-term, the proposed DWQMS will help underperforming water utilities to continuously improve performance over time and ensure safe delivery of drinking water for Canadians. This research provides training opportunities for 3 PhD, 3 MASc and 5 UG students, and one PDF in water management sector within an enriching academic environment and with relevant industry exposure throughout the program.******

我的研究的长期目标是开发决策支持工具，以不断提高饮用水供应的可靠性和可访问性。在过去的5年中，我的NSERC-DG的主要重点一直在为大型市政当局制定供水系统（WSS）的风险管理策略。但是，加拿大约有95％的WSS被归类为中小型水公用事业（SMWUS）。需要一个饮用水质量管理系统（DWQM），以有效地管理WSS及其相关危害中的关键控制点。该研究计划提出了一种“持续的绩效改进”方法，用于在DWQM中实施短期和长期资产管理策略。短期目标包括三个主要主题：（1）风险识别和绩效基准测试，（2）风险评估和（3）（3）持续绩效改善的风险管理。风景，并有助于开发通用和可扩展的模型。在主题1中，将确定并开发出“水质失败”风险的源头绩效指标。这将有助于建立基于风险的绩效基准，并量化WSS中水质失败的总体风险。在主题2中，将评估季节性和地理因素的影响，并使用Bow-tie分析开发风险量化模型。这将导致确定适当的干预措施，并在不同的操作条件下确定“剩余风险”。在主题3中，将进行生命周期福利成本分析，以确定其生命周期所选干预措施的剩余风险，成本和环境影响。多目标优化将重点介绍“最佳”风险管理策略作为WSS关键控制点的干预措施的组合。这将推动最佳管理实践和政策指南，以制定全面的水安全计划，以确保SMWUS的性能继续提高。****在短期内，建立了基准，以符合现有的监管要求，但在未来的几年中设置了更严格的基准（例如，国际健康指南，大型城市的国际健康准则，大型城市的基准）。从长远来看，拟议的DWQM将帮助表现不佳的水公用事业继续提高绩效，并确保安全地为加拿大人提供饮用水。这项研究为3位博士学位，3个MASC和5名UG学生提供了培训机会，以及在整个计划中具有丰富的学术环境中的水管理部门的一名PDF。******
