INTRODUCTION Canada has a $31B water infrastructure deficit, due in large part to aging water systems. Asset management programs adopted by municipalities lack advanced data analysis, hydraulic modelling, and optimization which are crucial to making sound decisions about billion dollar investments in water main assets. Fluctuations in available financial resources, the varied state of deterioration of water mains, and coordination with road reconstruction projects complicate decisions about when, where, and how to rehabilitate water main assets. The research program will produce new knowledge and models to assist municipalities in making strategic investments in the rehabilitation of water main assets that will save them hundreds of millions of dollars. The research program will train 6 HQP (5 Doctoral students and 1 Master’s student) who will acquire highly-desired technical skills in water distribution system modelling and assume leadership positions as water professionals. PROPOSED RESEARCH PROGRAM The program’s long-term objective is to develop a new platform of decision support and analysis models to optimize the scheduling of water main asset replacement and rehabilitation. Municipalities who adopt this new approach will be able to achieve multi-million dollar savings in infrastructure and electricity costs. Research conducted by 5 Doctoral and 1 Master’s students will use advanced statistical analysis methods and laboratory investigations to understand the links between soil, pipe, and environmental variables and pipe breaks and leakage. The research will use supervised learning theory, life-cycle costing, and advanced hydraulic modelling and optimization to develop new decision support models to help municipalities optimize the timing of pipe rehabilitation and the allocation of their financial resources. RESEARCH OUTCOMES The research will develop new knowledge and a new platform of models to help Canadian municipalities undertake cost-effective water main replacement and rehabilitation programs. The research will create fundamental knowledge surrounding the factors that drive breaks and leaks in networks. The research will lead to the development of a new water main asset management framework that is based on rigorous laboratory investigations and advanced modelling principles. The novel framework will be used to generate new knowledge on the best economic timing for replacement and rehabilitation of deteriorated cast iron and ductile iron pipe stocks in Canadian water systems. This new knowledge will help Canadian municipalities save millions of dollars in operation (electricity) and emergency break repair costs. The research and its application will be of intense interest to international researchers in the US, UK, Australia and other countries that face similar water main infrastructure challenges. HQP TRAINING The workforce in Canadian municipalities is aging and advances in water technologies have made the management of water systems more complex. This has created a large demand for highly trained water professionals with advanced technical and professional skills in Canadian municipalities and across the water industry. The proposed research program will benefit Canada by training 6 HQP who will acquire highly-desired technical skills in water distribution system modelling, water infrastructure asset management and planning, economic and risk analysis, optimization, and skills in professional management in engineering. HQP will be ready to assume leadership positions as water professionals in municipalities, regulatory agencies, provincial ministries and federal departments, and consulting firms. HQP will undertake leading roles in infrastructure planning and design.

介绍 加拿大有310亿美元的水基础设施赤字，这在很大程度上是由于供水系统老化。市政当局采用的资产管理计划缺乏先进的数据分析，水力建模和优化，这对于就数十亿美元的水主要资产投资做出正确决策至关重要。现有财政资源的波动、水管损坏的不同状况以及与道路重建项目的协调，使关于何时、何地和如何修复水管资产的决定变得复杂。该研究计划将产生新的知识和模型，以帮助市政当局在修复供水主要资产方面进行战略投资，这将为他们节省数亿美元。该研究计划将培养6名HQP（5名博士生和1名硕士生），他们将获得配水系统建模方面的高度期望的技术技能，并担任水务专业人员的领导职务。 拟议研究计划 该计划的长期目标是开发一个新的决策支持和分析模型平台，以优化水管资产更换和修复的时间安排。采用这种新方法的城市将能够在基础设施和电力成本方面节省数百万美元。由5名博士生和1名硕士生进行的研究将使用先进的统计分析方法和实验室调查，以了解土壤，管道和环境变量与管道破裂和泄漏之间的联系。该研究将使用监督学习理论，生命周期成本计算以及先进的水力建模和优化来开发新的决策支持模型，以帮助市政当局优化管道修复的时间和财政资源的分配。 研究成果 该研究将开发新的知识和新的模型平台，以帮助加拿大市政当局进行具有成本效益的水管更换和修复计划。该研究将围绕驱动网络中断和泄漏的因素创建基础知识。该研究将导致开发一个新的水主要资产管理框架，该框架基于严格的实验室调查和先进的建模原则。新的框架将被用来产生新的知识的最佳经济时机的更换和修复恶化的铸铁和球墨铸铁管股票在加拿大的供水系统。这些新知识将帮助加拿大市政当局节省数百万美元的运营（电力）和紧急中断维修费用。这项研究及其应用将引起美国、英国、澳大利亚和其他面临类似水管基础设施挑战的国家的国际研究人员的浓厚兴趣。 HQP培训 加拿大城市的劳动力正在老化，水技术的进步使水系统的管理更加复杂。这使得加拿大各城市和整个水务行业对训练有素、拥有先进技术和专业技能的水务专业人员产生了巨大的需求。拟议的研究计划将通过培训6名HQP使加拿大受益，他们将获得配水系统建模，水基础设施资产管理和规划，经济和风险分析，优化以及工程专业管理技能方面的高度期望的技术技能。HQP将准备担任市政当局，监管机构，省级部委和联邦部门以及咨询公司的水专业人员的领导职务。HQP将在基础设施规划和设计方面发挥主导作用。
