现代城市社会在很大程度上依赖于饮用水供应等关键的生命线系统。美国的供水系统包括大约100万英里长的相互连接的管道，这些管道在处理厂、泵站、储罐和阀门的支持下，将水从源头输送到消费点。虽然一些地区的淡水资源枯竭令人担忧，但供应基础设施的困境加剧了实现供应可靠性目标的问题。在过去的几张ASCE基础设施报告卡中，供水基础设施的质量被评为“D”或更低的等级，这证明了供水基础设施的质量已经下降到美国每年有24万个水管故障的程度。这些故障中的大多数导致了重大的经济、环境和社会后果。主动修复恶化的基础设施将避免这些不必要的故障后果。本文采用实证分析方法，对大直径输水管道的经济、环境和社会后果进行分析，估算其总体影响成本。收集和综合了11次大直径主水管破坏的影响资料。本文的结果将有助于预测未来供水管道失效的后果，从而实现基于风险的供水系统长期资本改进规划。©2015作者。Elsevier Ltd.出版。2015可持续设计、工程与建设国际会议组委会负责同行评审。
Modern urban societies depend greatly on critical lifeline systems such as drinking water supply. Water supply systems in the United States comprise about one million mile length of interconnected pipelines that transport water from sources to consumption points with the support of treatment plants, pumping stations, storage tanks and valves. While depleting freshwat er sources in some regions is an alarming concern, supply infrastructure woes exacerbate the problem of meeting supply reliability targets. Evidenced by the “D” or lower grade it has been receiving over the past few ASCE infrastructure report cards, the quality of water supply infrastructure has degraded to an extent where 240,000 water mains fail annually in the U.S. A majority of these failures result in significant economic, environmental and societal consequences. Pro-active rehabilitation of deteriorated infrastructure will avoid these unwarranted failure consequences. This paper employs empirical analysis of the economic, environmental and societal consequences of large-diameter water main failures to estimate their overall impact cost. Data on the impacts of 11 large-diameter water main failures has been gathered and synthesized. The results of this paper will aid in predicting the future water main failure consequences to enable risk-based, long-term capital improvement planning of water supply systems. © 2015 The Authors.
