“…Decreased pressure reduces water leakage from pipes, lowers pipe burst frequency and may reduce water consumption [1]. The device that is by far the most widely used to reduce pressure in a water distribution system (WDS) is a pressure control valve (PCV): commonly a pressure reducing valve (PRV) [2,3].…”

The control of pressure at a remote critical node using a pressure control valve is a highly effective way to attain pressure management. To perform real-time control, various kinds of controllers can be used, including flow-dependent controllers. These controllers calculate valve setting adjustment based both on the deviation of the pressure from the set-point and on the flow rate at the valve site. After putting all the flow-dependent controllers present in the scientific literature within the same framework, this paper presents a numerical comparison of their performance under realistic conditions of stochastic demand. Two controllers were selected for the comparison, namely the simple LCF (parameter-less proportional controller with known constant pressure control valve flow); and LVF (parameter-less controller with known variable pressure control valve flow), which uses a flow rate forecast. Indeed, this study considered an upgrade of LVF, in which the flow rate forecast was tailored to the conditions of stochastic demand. The application in a specific example network proved the performance of these controllers to be quite similar, although LCF was preferable due to its simple structure. For LCF, the average pressure at the critical node had a clear relationship to the consumption pattern. LVF outperformed when the hourly variation dominates the fluctuations in the flow. The conditions under which this out-performance occurred are comprehensively discussed.

“…It is unfortunately painful to say that those administrations facing with water loss are not paying enough attention to productivity (Ferrari and Savic 2015). A productive administration management should consist of a system that pays attention to strategies to combat with water losses (Adedeji et al 2018) and their reduction to an acceptable level (Ahopelto and Vahala 2020). This should be the right strategy, which should easily be followed up by every administrational system.…”

The population growth and urbanization have gained importance in the Water Resource Management (WRM) works. The classic approach in relation to the development of the water resources has lost its sustainability. Water has, therefore, become an important, but also becoming a scarce natural source due to the global warming and its climate change impacts end results. The major aim of WRM is to increase the Water Distribution Network (WDN) to keep water supply sustenance by decreasing the water demand. The new approaches in relation to the WRM should take into consideration in a more refined manner the supply–demand balance with the improvements in the WDN. Recently, water resources performance improvements have become one of the significant investment topics in Turkey. However, data from the Turkish Statistical Institute and any academic research in this field have shown that there is a water loss of around 50% in the current water supply and distribution systems. In comparison to other developed countries, this loss is very high. It became, therefore, necessary that each Water Resources Administration should keep track on the costs, water leakage losses and the necessary technological investments. In the scope of this study, water loss levels reduction strategy possibilities are developed in the Sakarya City WDM system, Turkey. These strategies field applications have been presented in detail. Finally, the extent of accuracy in these strategies has been shown, which may provide guidance for other water administrations departments in the world.

Modern water distribution networks (WDNs) are complex and difficult to manage due to increased level of urbanization, varying consumer demands, ageing infrastructure, operational costs, and inadequate water resources. The management problems in such complex networks may be classified into short-term, medium-term, and long-term, depending on the duration at which the problems are solved or considered. To address the management problems associated with WDNs, mathematical models facilitate analysis and improvement of the performance of water infrastructure at minimum operational cost, and have been used by researchers, water utility managers, and operators. This paper presents a detailed review of the management problems and essential mathematical models that are used to address these problems at various phases of WDNs. In addition, it also discusses the main approaches to address these management problems to meet customer demands at the required pressure in terms of adequate water quantity and quality. Key challenges that are associated with the management of WDNs are discussed. Also, new directions for future research studies are suggested to enable water utility managers and researchers to improve the performance of water distribution networks.
