The BATtle of the Attack Detection ALgorithms (BATADAL) is most recent competition on planning and management water networks undertaken within Water Distribution Systems Analysis Symposium. goal battle was to compare performance algorithms for detection cyber-physical attacks, whose frequency has increased in last few years along with adoption smart technologies. design challenge set C-Town network, a real-world, medium-sized distribution system operated through programmable logic...
Management of large water distribution systems can be improved by dividing their networks into so‐called district metered areas (DMAs). However, such divisions must based on appropriated technical criteria. Considering the importance deeply understanding relationship between DMA creation and these criteria, this work proposes a performance analysis generation that takes account indicators as resilience index, demand similarity, pressure uniformity, age (and thus quality), solution...
Water distribution networks (WDNs) are designed to meet water demand with minimum implementation costs. However, this approach leads poor long-term results, since system resilience is also minimal, and requires the rehabilitation of network if expanded or increases. In addition, in emergency situations, such as pipe bursts, large areas will suffer shortage. use a criterion for WDN design difficult task, its economic value subjective. Thus, paper, it proposed that trunk (TNs) rehabilitated...
One of the primary concerns in water supply systems is pressure control. High increases both leakage and risk pipes bursting, while low can reduce supplied to consumers allow intrusion pathogens. Therefore, operation equipment must be optimized avoid such problems. In high zones, reducing valves (PRVs) are commonly used for However, energy dissipated from head loss could recovered produce electrical energy. The use pumps as turbines (PAT) this case an alternative improve system efficiency....
The design of district metered areas (DMA) in potable water supply systems is paramount importance for utilities to properly manage their systems. Concomitant main objective, namely, deliver quality consumers, the benefits include leakage reduction and prompt reaction cases natural or malicious contamination events. Given structure a distribution network (WDN), graph theory basis DMA design, clustering algorithms can be applied perform partitioning. However, such sectorization entails number...
Water supply utilities need to properly manage their systems guarantee a quality supply. One way large is through division into district metered areas (DMAs). Graph clustering with an unknown number of subdivisions, as in social network theory, has proven highly efficient this sectorization problem. Several physical and hydraulic features may easily be used criteria suitably divide the network. This paper uses community detection algorithms define several DMA scenarios. Configurations mainly...
New environmental paradigms imposed by climate change and urbanization processes are leading cities to rethink urban management services. Propelled technological development the internet of things, an increasingly smart has favored emergence a new research field, namely, city. Within this way considering cities, water systems emerging for planning, operation, distribution networks (WDNs) with maximum efficiency derived from application data analysis other information technology tools....
Operational and economic aspects of water distribution make demand forecasting paramount for systems (WDSs) management. However, introduces high levels uncertainty in WDS hydraulic models. As a result, there is growing interest developing accurate methodologies forecasting. Several mathematical models can serve this purpose. One crucial aspect the use suitable predictive variables. The most used variables involve weather social aspects. To improve interrelation knowledge between various...
Abstract The development of computational models for analysis the operation water supply systems requires calibration pipes' roughness, among other parameters. Inadequate values this parameter can result in inaccurate solutions, compromising applicability model as a decision-making tool. This paper presents metamodel to estimate pressure at all nodes distribution network based on artificial neural networks (ANNs), using set field data obtained from strategically located sensors. approach...
A large volume of the water produced for public supply is lost in systems between sources and consumers. An important—in many cases greatest—fraction these losses are physical losses, mainly related to leaks bursts pipes consumer connections. Fast detection location plays an important role design operation strategies loss control, since this helps reduce from instant event occurs until its effective repair (run time). The transient pressure signals caused by contain information about their...
Leakages in distribution networks reach more than 30% of the water supplied, entailing important risks for infrastructure with contamination issues. Therefore, it is necessary to develop new methods mitigate amount wastes. This study proposes seek sources information that can help a sustainable use. Hence, an analysis network presented, showing hydraulic behavior during leaks occurrence, placing emphasis on how these events affect and modify quality parameters, such as age chlorine...
Abstract The expansion of water distribution networks is nowadays essential to meet the pressing population growth in many cities worldwide. With subsequent increase demand, hydraulic behaviour a supply system can change dramatically due significant head losses pipes caused by larger flows released pumping systems and reservoirs higher consumption network. Strategical studies are necessary delimit risk regions where demand may affect too negatively. To analyse scenarios with lowest failure...

Abstract Leakages in water distribution networks (WDNs) affect the hydraulic state of entire or a large part network. Statistical correlation computed among pressure sensors monitoring network nodes aids detection and localization such leaks.
