Abstract

The need for water supply companies to exercise control over the operating conditions of water supply networks has contributed to the development of a number of methods for their diagnosis. The diagnostics of technical infrastructure is a constantly developing field, and therefore, over the years, we have observed the development of various methods of diagnosing network operating conditions and their classification. The article presents, in a synthetic way, the division and review of the previously used methods of diagnosing the operating conditions of water supply networks. The authors also classified and assessed the usefulness of the methods of diagnosis in specific operating conditions. The review carried out by the authors shows that there is a need for research on the detection of operating conditions of water supply networks under the operating conditions of real systems. The results of our deep analysis allow for the understanding of the most important areas of research, as well as the existing worldwide trends in the development of methods for leak diagnosis and detection in water distribution networks. This review is a compendium of knowledge on the detection and diagnosis of water supply networks.

Highlights

The conditions of water distribution systems depend on many deterministic and random factors [1]
The operational condition of a system, object, or technical device is a momentary phase of exploitation, which is described by the results of measurements of physical quantities that characterize the operational features of the system or its individual components
Most contemporary scientific studies place the greatest emphasis on diagnosing the operating conditions of a water supply network but mainly in the context of its failure rate and potential water leakage [6], while they are less related to the detection of abnormal conditions related to its operation

Summary

Introduction

The conditions of water distribution systems depend on many deterministic and random factors [1]. Most contemporary scientific studies place the greatest emphasis on diagnosing the operating conditions of a water supply network but mainly in the context of its failure rate and potential water leakage [6], while they are less related to the detection of abnormal conditions related to its operation. Such situations may include the outbreak of the COVID-19 pandemic, as studies indicate a significant increase in residential water use following the introduction of government restrictions [7]. The random nature of water consumption, and the hydraulic parameters achieved as a result, presents a serious barrier to assessing whether or not the operating condition of a network can be considered relatively normal
