Energy Cost Savings in Canadian Water Distribution Systems Through Data Analytics

引言 目前，没有关于加拿大水务行业自来水总管和商业修复技术的能源表现的数据。这是在供水行业实现重要能源和温室气体(GHG)节约的最佳方式方面做出循证决策的一大障碍。大多数市政当局和管道修复公司没有资源来执行高级能源建模和优化，以确定管道修复技术何时以及如何提高其系统的能效。 研究目标 该研究计划的长期目标是创造有关管道资产修复和系统运行的新知识和指导方针，为加拿大市政当局节省数亿美元的能源成本。短期目标包括：1)开发水力模型和能源数据的综合数据库；2)开发创新的能源指标，以量化自来水干管和管道修复技术的能源性能；3)先进的多元统计分析，以确定导致自来水干管能源性能差的重要因素；以及4)先进的水力和能源建模，以确定何时以及采用何种创新的商业管道修复技术将在加拿大供水系统中实现最大的能源成本节约。 研究成果及意义 这项研究将产生关于自来水管道和修复技术的能源性能的新知识和广泛的数据集。这将改进最佳实践和政策指导方针，涉及以下方面：1)修复供水干管的最佳时机，以保持较低的抽水/能源成本；以及2)最有效的商业修复和清洁技术，将在加拿大供水系统中产生最高的能源/运营节约。这些创新的政策指导方针将帮助加拿大市政管理者更好地构建管道修复计划，以利用能源效率并降低数亿美元的能源成本。5名HQP(4名博士，1名硕士)将接受培训，获得市政当局、咨询公司和政府大量需要的供水系统分析、能源分析和统计分析方面的最新知识和分析技能。

INTRODUCTION Currently there is no data on the energy performance of water mains and commercial rehabilitation technologies in the Canadian water industry. This is large barrier to making evidence-based decisions concerning the best way to achieve important energy and greenhouse gas (GHG) savings in the water provision industry. Most municipalities and pipe rehabilitation companies do not have the resources to perform advanced energy modelling and optimization to determine when, and with what, pipe rehabilitation technologies will improve the energy efficiency of their systems. RESEARCH OBJECTIVES The long-term objective of the research program is to create new knowledge and guidelines on pipe asset rehabilitation and system operation that will save Canadian municipalities hundreds of millions of dollars in energy costs. The short-term objectives include: 1) development of a comprehensive database of hydraulic models and energy data, 2) development of innovative energy metrics to quantify the energy performance of water mains and pipe rehabilitation technologies, 3) advanced multivariate statistical analysis to identify the important factors that lead to a poor energy performance in water mains, and 4) advanced hydraulic and energy modelling to identify when and with what innovative commercial pipe rehabilitation technologies will produce the greatest savings in energy costs in Canadian water systems. RESEARCH OUTCOMES AND SIGNIFICANCE The research will lead to the creation of new knowledge and an extensive data set on the energy performance of water mains and rehabilitation technologies. This will lead to improved best practices and policy guidelines concerning: 1) the optimal timing of water main rehabilitation to keep pumping/energy costs low, and 2) the most effective commercial rehabilitation and cleaning technologies that will yield the highest energy/operational savings in Canadian water systems. These innovative policy guidelines will help Canadian municipal managers better structure their pipe rehabilitation programs to take advantage of energy efficiency and reduce energy costs on the order of hundreds of million dollars. Five HQP (4 PhD, 1 MASc) will be trained and acquire state-of-the-art knowledge and analytical skills in water distribution system analysis, energy analysis, and statistical analysis that are in large demand in municipalities, consulting firms, and government.
