Sustainability of water supply infrastructure: a risk-based framework

我研究的长期目标是为市政、地区/省和联邦机构制定和实施一个基于风险的决策框架，用于资源分配和资本投资，以确保饮用水供应的可持续性，并改善加拿大人获得安全饮用水的机会。拟议的研究计划的主旨是开发新的技术、模型和决策支持工具。本研究将对饮用水供应一体化管理有新的认识和认识。这项研究中开发的模型、技术和工具将基于最先进的数学和统计方法。该研究计划包括四个主要主题，包括：1)水源保护；2)供水系统的可靠性；3)配电网的水质模型；以及4)供水基础设施的资产管理。 获得“安全”和“负担得起”的饮用水是一项基本人权。尽管这个问题在西方世界的大部分地区得到了部分解决，但由于人口增长、工业化和资源枯竭/退化等压力越来越大，它仍然构成了严重的威胁。许多国际机构/组织(如《波恩宪章》、世卫组织准则)强调必须对供水系统进行积极的风险管理。拟议研究方案的主要特点是不仅侧重于管道末端的验证和管理控制系统的实施(即定期水质监测)，而且还强调需要评估整个供水系统所有点的风险。从长远来看，拟议的风险管理框架还将提高自来水公司解决与安全有关的事件引起的水质问题的能力。一批高素质的人员(HQP)将在拟议的研究计划过程中接受培训。该研究计划将为水务行业准备HQP，并将帮助他们发展分析和解决问题的技能，这将有助于他们在工程行业的一般安置。

The long-term objective of my research is to develop and implement a risk-based decision-making framework for Municipal, Territorial/ Provincial and Federal agencies for resource allocation and capital investment that will assure sustainability of drinking water supply and improve accessibility of safe drinking water for Canadians. The main thrust of the proposed research program is towards developing new techniques, models and decision support tools. In this research, new knowledge and understanding of integrated management for drinking water supply will be developed. Models, techniques and tools developed in this research will be based on state-of-the-art mathematical and statistical methods. The research program encompasses four major themes that include: 1) source water protection; 2) reliability of water supply system; 3) water quality modelling in distribution networks; and 4) asset management of water supply infrastructure. Access to 'safe' and 'affordable' drinking water is a basic human right. Though the problem is partially resolved in most of the Western World, it still poses serious threats due to increasing pressures like, population growth, industrialization, and resource depletion/ degradation. Many international agencies/ organizations (e.g., Bonn Charter, WHO guidelines) emphasize the need for proactive risk management of water supply systems. The main feature of the proposed research program is to focus not only on the end-of-pipe verification and implementation of management control systems (i.e., regular water quality monitoring) but also emphasizes the need for evaluation of risks at all points throughout the water supply system. In the longer run, the proposed risk management framework will also improve water utilities' abilities to address water quality issues stemming from security-related events. A pool of highly qualified personnel (HQP) will be trained over the course of the proposed research program. The research program will prepare HQP for water sector, and will also help them to develop analytical and problem solving skills that will be useful for their placement in engineering industry in general.
