废水管道泄漏是欧洲一个新出现的问题，特别是关于泄漏废水对地下水污染的潜在影响以及渗透对下水道网状系统管理的影响。本文件介绍了澳大利亚与几个欧洲伙伴合作，努力开发决策支持工具，优先考虑积极修复废水管道网络，以解决渗漏问题。在决策支持系统的基本模型中，泄漏被视为管道系统恶化的函数。该模型依赖于整个服务区域的土壤类型识别，以确定管道环境的侵略性，并根据管道特性和操作条件将区域划分为区域。通过了解管道材料、操作条件和管道环境之间的相互作用导致管道恶化的机制，这些模型可以预测整个网络不同区域的泄漏率。决策支持系统利用这些模型来预测各个区域的管道状况，并通过针对泄漏率最高的区域来优化修复资源的利用。
Wastewater pipeline leakage is an emerging concern in Europe, especially with regards to the potential effect of leaking effluent on groundwater contamination and the effects infiltration has on the management of sewer reticulation systems. This paper describes efforts by Australia, in association with several European partners, towards the development of decision support tools to prioritize proactive rehabilitation of wastewater pipe networks to account for leakage. In the fundamental models for the decision support system, leakage is viewed as a function of pipeline system deterioration. The models rely on soil type identification across the service area to determine the aggressiveness of the pipe environment and for division of the area into zones based on pipe properties and operational conditions. By understanding the interaction between pipe materials, operating conditions, and the pipe environment in the mechanisms leading to pipe deterioration, the models allow the prediction of leakage rates in different zones across a network. The decision support system utilizes these models to predict the condition of pipes in individual zones, and to optimize the utilization of rehabilitation resources by targeting the areas with the highest leakage rates.
