“…Take major urban centers in Canada as example. Statistics Canada (Trudeau 2020) reported fair to very poor conditions for a significant portion of the WDNs. One simple reason is that these WMs have reached or are reaching the end of expected service life.…”

This study presents a review of the state-of-the-art literature on water pipe failure predictions, assessment of water losses risk, optimal pipe maintenance plans, and maintenance coordination strategies. In addition, it provides a categorization of water main (WM) failures as well as a taxonomy of WM maintenance strategies. In particular, predictive and prescriptive analytics are highlighted with the investigation of their contributions and drawbacks from methodological and application perspectives. This review aims at providing a review of failure analytics developed recently in water mains domain either for prediction of failure or identification of optimal maintenance strategies conjointly. Future research directions and challenges are elaborated in advancing the understanding about the mechanisms leading to failures. The existing gaps between theory and practice in managing assets across water distribution networks ensuring cost-effectiveness and reliability are discussed. As knowledge about the state of the water mains and related areas is crucial, thus, this review provides an state-of-the-art update from recent studies, and accordingly, presents and discusses avenues for future research.

“…Various researchers have been finding numerous approaches/models to assess urban water quality about different objectives and parameters. Co‐production approach for developing urban water security indicators and coordinated research to deal with the confronts of urban water management for policy developments were other approaches studied by the investigators (Brown & Keath, 2008; Gómez et al., 2012; Jensen & Wu, 2018; Trudeau, 2020). Novotny (1996) suggested that reduction of waste flows and increase of water assimilative capacity needs to be considered for integrated water quality management of receiving waters.…”

In the present study, Amaravati, the proposed city of India is considered to assess the impacts of urbanization on water quality of the Krishna River in the vicinity. Long‐term surface water quality data of various parameters of Krishna River are obtained from Central Water Commission (CWC). Trends of various parameters are analyzed using a modified version of Mann‐Kendall (M‐K) test; bootstrapped M‐K trend test with optional bias corrected pre‐whitening and R programming are used affecting water quality prior to and at the commencement of urbanization. During the onset of urbanization, minimum BOD is decreased from 0.49 to 0.2 mg/L, while the maximum BOD is increased by 67.7%. Dissolved oxygen's (DO) minimum value is decreased by 29.33% while maximum DO value is decreased by 4.47% at the beginning of urbanization. During the process of urbanization, total coliform's minimum count is increased to 330 from 2 MPN/100 ml while the maximum count of total coliforms is increased to 16,000 from 2400 MPN/100 ml. Faecal coilform's minimum count is increased from 2 to 80 MPN/100 ml while maximum count is increased to 16,000 from 800 MPN/100 ml during urbanization. It is found that due to urbanization, pH, DO values exceed the allowable limit.

“…We follow with a number of research articles and commentaries that look at SWM in three general ways: within the 'conventional' utility framework (Grigg, 2020); stretching the domain of SWM without questioning its purpose (Bjornlund et al, 2020;Moniz et al, 2020;Schweitzer et al,2020); and stepping back and looking at SWM with a critical but not dismissive eye (Hartley & Kuecker, 2020;Trudeau, 2020). Grigg (2020) sees SWM as definitely positive in its ability to increase the operational capacity of water utilities.…”

This is the second special issue prepared on behalf of the International Water Resources Association (IWRA) under the aegis of its Science, Technology and Publications Committee. The first, we hope you recall, appeared in April 2018 (vol. 41, no. 3): The Wicked Problems of Water Governance. These IWRA special issues are intended to complement existing IWRA initiatives. As foreshadowed in the earlier special issue, the focus of this one is Smart Water Management (SWM). It evolved from a collaboration with K-water, the Korean water authority, that resulted in a report including a number of case studies of SWM from around the world. Following this introduction is a summary of the findings of that report, including a description of what SWM is (in a nutshell, the application of new technologies to water management), a general characterization of its progress to date, a summary of findings (benefits, factors for success and policy recommendations), and prospects for further development (Kuisma, Clench, et al., 2020). We follow with a small sample of summaries of the cases in that collection, from Mexico (Villareal et al., 2020), Korea (Yi et al., 2020) and France (Tabuchi et al., 2020), covering a range of issues and domains, from water quality monitoring at a campus level, to a nationwide flood monitoring system, to the sanitation sector of a global city. Villeareal et al. present a case of the development of SWM technology on a major university campus (UNAM) in Mexico. Here the project, focused on data monitors managed by a specific programme with the acronym PUMAGUA, has been aimed at improving water quality, reducing water consumption and encouraging behavioural change in students and the university community. This programme has reduced potable water consumption by 50% through improved practices and leak detection, while improving the quality of drinking water, treating wastewater to levels specified in Mexican regulations, and promoting participation of the entire university community in using water more efficiently. Yet the authors note that while SWM can build trust in water users, it requires a lot of time and effort to manage and maintain, especially in the early stages of its implementation. Given the speed and scope of technological change, they further argue that it is essential to have the financial resources and capacity to maintain and upgrade technology to ensure that is continues to yield benefits. Yi et al. (2020) showcase the ability of SWM to significantly improve drought and flood management for an entire country (in this case, South Korea) through the use of an
