Urban water supply networks are crucial for the transportation of water resources. However, with the increasing frequency and severity of cold wave disasters linked to climate change, the impact on water supply systems has become a critical concern. These impacts include pipe failures, customer water outages, and challenges in meeting peak winter water demand. To address this, our study analyzes data from cold waves in Shanghai from late 2020 to early 2021. We statistically examined daily water supply volume, pressure, and pipe failures to detect abnormal changes. We also analyzed pipe failure rates based on different characteristics to identify which pipes are most vulnerable to cold wave damage. Understanding the winter cold wave's effects can help water companies prioritize maintenance on aging pipes before such events, reducing damage and improving service. This research adds to the understanding of climate change's impact on urban infrastructure and provides valuable insights for global water companies to optimize their maintenance strategies.

极端寒潮对城市供水管网安全的影响分析——以2020-2021年为例


城市供水管网对于水资源的输送至关重要。然而，随着与气候变化相关的寒潮灾害的频率和严重程度不断增加，对供水系统的影响已成为一个重要问题。这些影响包括管道故障、客户停水以及满足冬季高峰用水需求的挑战。为了解决这个问题，我们的研究分析了2020年底至2021年初上海寒潮的数据。我们对每日供水量、压力和管道故障进行了统计，以发现异常变化。我们还根据不同的特征分析了管道故障率，以确定哪些管道最容易受到寒潮损坏。了解冬季寒潮的影响可以帮助自来水公司在此类事件发生之前优先对老化管道进行维护，减少损坏并改善服务。这项研究加深了人们对气候变化对城市基础设施影响的理解，并为全球水务公司优化其维护策略提供了宝贵的见解。
