Municipal water main infrastructure integrity management techniques

加拿大市政基础设施包括超过112，000公里的饮用水管道，占基础设施资产的重要部分。全国各城市的水管沿着以及其他基础设施都很陈旧，需要积极维护，以便经济和安全地向居民提供服务。现有基础设施的状况评估是主动维护的一个重要组成部分。先进的无损检测方法正被广泛应用于地下基础设施的状态评估。然而，无损检测方法的应用存在两个主要挑战。首先，非破坏性测试的结果需要考虑到成功应用的不同现场特定条件进行适当的解释。其次，一般不可能一次将检测技术应用于整个管网。网络中的管道需要优先考虑最佳利用检查工具和资源，以确保及时识别关键管道组件。拟议的研究通过应用于纽芬兰和拉布拉多省的珍珠山市来解决这些挑战。将使用珍珠山市拥有的声学系统来检查城市水管。将在纪念大学对视察数据进行分析，以确定不同场地条件下的信号处理参数。管道检查的结果沿着基础设施的数据将用于开发一种方法，该方法将有助于城市优先考虑管道基础设施的检查和维护。研究结果可能会被加拿大其他社区用来尽量减少水管故障事件，从而改变加拿大人的生活。这也将最大限度地减少城市与水管故障有关的经常性开支。经过培训的HQP将传播知识，推进技术，并通过在行业和/或学术界工作为加拿大经济做出贡献。

Canadian municipal infrastructure includes more than 112,000 km of drinking water pipelines, representing a significant part of the infrastructure asset. The water mains along with other infrastructure in the municipalities across the country are old and require proactive maintenance to deliver service to the residents economically and safely. The condition assessment of existing infrastructure is a major component for the proactive maintenance. Advanced non-destructive testing methods are being widely used for inspection of buried infrastructure for the condition assessment. However, there are two major challenges with application of the non-destructive testing methods. Firstly, the results from the non-destructive testing require proper interpretation considering different site specific conditions for successful application. Secondly, it is generally not possible to apply the inspection technology to the entire pipeline network at a time. The pipelines in the network require prioritization for optimum utilization of the inspection tool and the resources to ensure that the critical pipe components are recognized in due time. The proposed research addresses these challenges through application to the City of Mount Pearl in the province of Newfoundland and Labrador.The city water mains will be inspected using an acoustic system owned by the City of Mount Pearl. The inspection data will be analysed at Memorial University to develop signal processing parameters under different site conditions. The results of the pipeline inspection along with data on the infrastructure will be used to develop a method that will be useful for the city in prioritizing the pipeline infrastructure for inspection and maintenance. The outcome of the research would potentially be used by other communities in Canada to minimize water main failure incidents and thus make a difference in the lives of Canadians. This will also minimize the recurrent expenditure of the cities associated with water main failures. The trained HQP will disseminate the knowledge, advance the technology, and contribute to Canadian economy through working in the industry and/or academia.
