The Battle of the Water Networks II (BWN-II) is latest a series competitions related to design and operation water distribution systems (WDSs) undertaken within Distribution Systems Analysis (WDSA) Symposium series. BWN-II problem specification involved broadly defined for an existing network that has be upgraded increased future demands, addition new development area. decisions parallel pipes, storage, operational controls pumps valves, sizing backup power supply. Design criteria hydraulic,...
Water temperature is often monitored at water sources and treatment works; however, there limited monitoring of the in drinking distribution system (DWDS), despite a known impact on physical, chemical microbial reactions which quality. A key parameter influencing soil temperature, influenced by urban heat island effects.

This paper shows how pipe replacements and control valve installations can be optimized in water distribution networks to reduce leakage, under minimum nodal pressure constraints. To this end, a hybrid multiobjective algorithm, which has diameters positions settings as decisional variables, was set up. The algorithm also enables identification of the isolation valves that have closed order improve effectiveness installed. is initially applied optimal location problem, where it explores...
One of the main factors contributing to water scarcity is loss in distribution systems, which mainly arises from a lack adequate knowledge design process, optimization availability, and poor maintenance/management system. Thus, perspective sustainable integrated management resources, it essential enhance system efficiency by monitoring existing elements enhancing network practices. The current study establishes smart grid (SWG) with digital twin (DT) for infrastructure improve monitoring,...

Additionally, research also conducts comparative examination two distinct...
This paper presents a holistic assessment framework for the impacts of water distribution pipe breaks to promote environmentally sustainable and socially resilient cities. considers social, environmental, economic vulnerabilities as well probabilities associated with failure. The integration these features provides comprehensive approach understanding infrastructure risks. Taking city Vancouver case study, social vulnerability index (SVI) is obtained following application cross-correlation...
In 2000, the resilience and failure indices were introduced as a convenient compact tool to express respectively water-distribution network (WDN) surplus deficit in satisfying users' demand, terms of delivered power. their original formulation, mentioned indices, originally thought WDN design tools, developed only considering demand-driven modeling approach, which would include pumps but not leakage. This paper extends formulation both presents generalized expression, more for use when...
This paper presents an economic analysis of pressure control solutions for leakage and pipe burst reduction. In detail, it explores the operating conditions under which installation conventional mechanical reducing valves (PRVs) or remotely real-time controlled (RTC) are cost effective compared to a scenario with no control. For range system sizes, hydraulic extended period simulations empirical formulas were used estimate rates bursts, respectively, in numerous operational scenarios,...

In numerical application herein described this is implemented within hydraulic simulation model tested case study network, which there only one valve, installed...
The detection of contaminant intrusion into a water-distribution network (WDN) is difficult issue due to uncertainty related the type injected contaminant, source location, and time. placement water quality sensors has received increasing interest in last years, it still represents an open problem great challenge for researchers utilities. Efficient numerical techniques are needed support any contamination warning system (CWS) design. These require well-calibrated hydraulic model WDN deal...
Because of the large computational burden associated with direct assessment reliability, indirect indices reliability have recently received more attention in framework water distribution system design. Two new energy-related for evaluation (i.e., available power index and pipe hydraulic resilience index) are developed this paper. The performance these is evaluated compared that four existing (three other indices—i.e., index, network modified index—and entropy-based method, i.e.,...
