Toward Sustainable Water Infrastructure: The State‐Of‐The‐Art for Modeling the Failure Probability of Water Pipes

Failures of water distribution networks (WDNs) are rising at an exponential rate, necessitating immediate attention. An effective way to reduce the failure rate is to develop accurate predictive models for the failure probability of water pipes, which are the most critical assets of WDNs. Despite th...

Description
Summary:Failures of water distribution networks (WDNs) are rising at an exponential rate, necessitating immediate attention. An effective way to reduce the failure rate is to develop accurate predictive models for the failure probability of water pipes, which are the most critical assets of WDNs. Despite the fact that researchers have invested efforts to develop various predictive models, the extant literature lacks a complete state‐of‐the‐art review. To fill this gap, this study employs a mixed approach (i.e., quantitative and qualitative) by providing (a) a bibliometric analysis of existing scholarly literature, (b) a systematic review of the techniques used in modeling the failure probability of water pipes, including physical, statistical, and machine‐learning (ML)‐based models, and (c) identified gaps and future research directions. The bibliometric analysis shows that ML‐based models are emerging and, hence understudied as compared to the physical and statistical‐based models. Regarding the systematic review, a proper understanding of the development of each model has been provided in addition to their advantages and critiques. Furthermore, failure probability integration methods are discussed. Findings reveal that the social and operation‐related predictors have been understudied, thereby suggesting their further exploration. This study adds to the existing body of knowledge by providing water utilities and academics with a comprehensive understanding of the probability of water pipe failure, which will be useful in the decision‐making process and network management. Plain Language Summary This study is motivated by the lack of a comprehensive review of existing models in predicting the failure probability of water pipes. In order to fill this gap, this study conducts a bibliometric and systematic review by critically analyzing the physical, statistical, and machine learning‐based models in the literature. A frequency analysis of the factors used in the development of the models was conducted, to determine the most influential factors. This research provides a complete reference for water utilities and academics on the prediction of water pipe failure, which would be useful in the decision‐making process. Key Points The state‐of‐the‐art of failure modeling of water pipes is demonstrated A conceptual framework for decision‐making process in water utility management is presented Key future directions for achieving more sustainable water distribution networks are discussed
