“…The installation of pressure-reducing valves (PRVs) in over-pressured networks has proven to be an effective way of controlling leakage, and the application of pressure management techniques has reduced water supply costs by 20-55% [31]. There are four recognized PM methods for PRVs, which are based on the critical point states [32], namely fixed-outlet (FO), pressure-modulated, time-modulated (TM) and flow-modulated (FM) methods [24,[33][34][35][36]. These techniques have been extensively studied by academics, and there are several case studies of their practical implementation, making them effective means of reducing pressure and leakage [37][38][39][40][41].…”

Leakage in water distribution systems (WDS) is a major problem that results in substantial resource wastage. Pressure management, which is based on optimized control strategies using pressure-reducing valve installation, is considered one of the most effective methods for controlling network leakage and can be broadly classified into varied types, depending on the different control strategies. When facing diverse operational conditions in actual engineering, selecting the most suitable optimization strategy for the specific water supply network can greatly control leakage and efficiently utilize water resources. This article employs a greedy algorithm to iteratively determine the control sequence for pressure-reducing valves (PRVs), with the objective of minimizing surplus pressure. Subsequently, it proposed five evaluation indicators, namely, daily flow, daily leakage, pressure imbalance indicator, median daily pressure at nodes, and water age, which are used to evaluate and compare pressure management strategies in two sample networks. Finally, a suitable control strategy was successfully developed and implemented for an actual WDS of Y city in southern China, resulting in significant achievements. In conclusion, this paper embodies our attempt and contemplation in formulating pressure management strategies under diverse operating conditions in WDS, with the objective of providing guidance for practical engineering applications.

“…Looking at the different end uses of residential water, showering or bathing often represents the highest indoor demand, accounting for 30% to 45% of total residential use (Energy Saving Trust, 2015;Water Research Foundation, 2016;Moslehi et al, 2020). There is also evidence that, among personal hygiene options, showering is preferred over bathing in developed countries.…”

Personal hygiene accounts for 30-45% of water use in households in OECD countries, and of this water, the greatest proportion is used in showering. More efficient showers can be achieved through the use of efficient technologies-mainly efficient showerheads-as well as through the adoption of sustainable habits, such as reducing shower frequency and duration. A review of the websites of water utilities in cities of OECD countries shows little effort to promote water-saving shower habits. Addressing this shortcoming would improve the sustainability of water use, compared to the current focus on efficient technologies.

Öz: İçme suyu dağıtım sistemlerinde meydana gelen arızaların ve sızıntıların azaltılması için çok farklı yöntemler uygulanmaktadır. Bu yöntemler zaman alıcı ve maliyetlidir. Bu nedenle yöntem uygulanmadan önce maliyet bileşenleri tanımlanmalıdır. Şebeke yenileme faaliyeti, kentsel su yönetiminde uygulanan yöntemler arasında en fazla maliyet oluşturan yöntemdir. Bu nedenle bir dağıtım sisteminde şebeke yenilemeye karar vermeden önce, gerekliliğin ortaya konulması, maliyet bileşenlerinin belirlenmesi ve hesaplanması ve bu analizlerin belirli bir standart yapıda gerçekleştirilmesi oldukça önemlidir. Bu çalışmada içme suyu dağıtım sistemlerinde şebeke yenileme faaliyetleri için fayda maliyet bileşenlerini dikkate alan ve analiz gerçekleştiren bir hesaplama modeli geliştirilmiştir. Bu hesaplama aracında şebeke yenilemede maliyet oluşturan tüm bileşenler saha verileri esas alınarak tanımlanmıştır. Ayrıca mevcut şebeke koşullarında şebekedeki boru malzeme ve çap dağılımları ve arıza oranları dikkate alınarak faydalı ömür analizi için model tanımlanmıştır. Bu modelde yeni yapılacak şebekedeki boru malzeme ve çap dağılımı da dikkate alınmakta ve fayda maliyet analizi gerçekleştirilmektedir. Geliştirilen bu hesaplama aracının özellikle belediye ve su idarelerinde karar vericiler ve teknik personel için referans teşkil edeceği düşünülmektedir.
