“…Because of corrosion, metallic buried structures must be regularly inspected, maintained, and occasionally replaced [7,8]. Furthermore, the failure of these structures presents serious risks to human health and the environment [9][10][11]. For instance, when a foundation fails, it is possible that the structure that it supports also fails or leads to the leakage of dangerous substances which can trigger dangerous explosions [12][13][14].…”

Around the world, there are thousands of metal structures completely or partially buried in the soil. The main concern in their design is corrosion. Corrosion is a mechanism that degrades materials and causes structural failures in infrastructures, which can lead to severe effects on the environment and have direct impact on the population health. In addition, corrosion is extremely complex in the underground environment due to the variability of the local conditions. The problem is that there are many methods to its evaluation but none have been clearly established. In order to ensure the useful life of such structures, engineers usually consider an excess thickness that increases the economic cost of manufacturing and does not satisfy the principles of efficiency in the use of resources. In this paper, an extended revision of the existing methods to evaluate corrosion is carried out to optimize the design of buried steel structures according to their service life. Thus, they are classified into two categories depending on the information they provide: qualitative and quantitative methods. As a result, it is concluded that the most exhaustive methodologies for estimating soil corrosion are quantitative methods fed by non-electrochemical data based on experimental studies that measure the mass loss of structures.

“…However, when pipe bursts occur, the lack of information makes the diagnostics task difficult. Pipe bursts cause water and energy losses (Colombo & Karney 2002), and can also lead to flooding of properties (Cooper et al 2000) and intrusion of contaminants into the WDS (Sadiq et al 2006). Timely detection and location of pipe bursts is therefore of primary interest to water utilities worldwide in order to improve their customer service, minimise leakage, preserve resources and thus minimise impact on the environment.…”

This paper presents a decision support methodology aimed at assisting Water Distribution System (WDS) operators in the timely location of pipe bursts. This will enable them to react more systematically and promptly. The information gathered from various data sources to help locate where a pipe burst might have occurred is frequently conflicting and imperfect. The methodology developed in this paper deals effectively with such information sources. The raw data collected in the field is first processed by means of several models, namely the pipe burst prediction model, the hydraulic model and the customer contacts model. The Dempster-Shafer Theory of Evidence is then used to combine the outputs of these models with the aim of increasing the certainty of determining the location of a pipe burst within a WDS. This new methodology has been applied to several semi-real case studies. The results obtained demonstrate that the method shows potential for locating the area of a pipe burst by capturing the varying credibility of the individual models based on their historical performance.

“…In addition, the achievement of the best performance requires a logical method that can estimate the optimal time and range of replacement/rehabilitation work while understanding the factors in the deterioration of pipe networks. In some advanced countries, many studies have been conducted and are utilized for pipeline replacement/rehabilitation work as well as for the management/operation of pipe networks [1][2][3].…”

A B S T R A C TPipelines are a very important component of water supply systems. Specially, the pipe bursts and leaks are very useful indicators to show the condition of the network. To keep and improve the performance of the system, much accumulated know-how for inspections, operation, maintenance, and suitable rehabilitation to achieve the best performance is needed, as well as a logical method that can estimate the optimal time and range of replacement/rehabilitation work with an understanding of deterioration factors of pipe networks. Therefore, in this study, a statistical probability model for pipe burst risk was developed with various data from leak-repairing records and local characteristics of the circumstance on the real-scale distribution system in Seoul in order to utilize this method for management and operation of the water pipe network, including prioritization of pipe replacement/ rehabilitation work.
