AB  - Water temperature is often monitored at water sources and treatment works; however, there
is limited monitoring of the water temperature in the drinking water distribution system (DWDS),
despite a known impact on physical, chemical and microbial reactions which impact water quality.
A key parameter influencing drinking water temperature is soil temperature, which is influenced by the urban heat island e ects. This paper provides critique and comprehensive summary of the current knowledge, policies and challenges regarding drinking water temperature research and presents the findings from a survey of international stakeholders. Knowledge gaps as well as challenges and opportunities for monitoring and research are identified. The conclusion of the study is that temperature in the DWDS is an emerging concern in various countries regardless of the water source and treatment, climate conditions, or network characteristics such as topology, pipe material or diameter. More research is needed, especially to determine (i) the e ect of higher temperatures, (ii) a legislative limit on temperature and (iii) measures to comply with this limit.

AB  - Sectorization of a water distribution network (WDN) into district metered areas (DMAs) is a proven solution for proactive leakage control. Traditionally, WDN sectorization is conducted by local experts using a trial-and-error approach, often resulting in the identification of arbitrary solutions. Some recently published methods try to improve WDN sectorization by automating the process,
especially by using optimization. Various sectorization criteria, constraints, and limitations are introduced, which often fail to consider the issues faced by poorly managed WDNs such as limited funds and shortage of water balance data. These methods also have poor computational efficiency imposed by optimization methods used. This paper presents a new distribution network sectorization method (DeNSE), that overcomes these deficiencies. This method is based on a heuristic procedure in which WDN sectorization is driven by efficient tracking of water balance data and determining the lowest cost investment needed to maintain the same level of operational performance. The above-mentioned set of criteria is particularly well suited for initial sectorization of WDNs when major uncertainties in water balance data often lead to poor management decisions. The DeNSE method is validated and benchmarked against other sectorization methodologies in a case study of a large, real-world WDN. The results show that DeNSE can identify sound, realistic sectorization solutions that are in some respects better than corresponding solutions reported in the literature. DeNSE also enables high computational efficiency, ensuring its applicability to real-world WDNs.

AB  - Different methods have been developed in the past to formulate and solve steady-state hydraulics of a water distribution system (WDS). The most widely used method nowadays is probably the global gradient algorithm (GGA). The loop-flow method (also known as the Q method) represents a viable alternative to GGA, especially when combined with suitably preprocessed network data. The main advantage of the Q method over the GGA is in the smaller number of unknowns to solve for, which is coming from the fact that real WDSs typically have far less loops than nodes. A new loop-flow-type method, relying on the novel triangulation based loops identification algorithm (TRIBAL) that was implemented in the corresponding new hydraulic solver (Q), is presented in this paper (TRIBAL-Q). The new method aims to exploit this advantage, while overcoming key drawbacks of existing Q methods. The performance of the TRIBAL-Q-based solver is compared with the GGA-based solver on four large real networks of different complexity and topology. The results obtained demonstrate that, despite requiring an increased number of iterations to converge, the TRIBAL-Q method-based solver is substantially computationally faster, has slightly better numerical stability, and is equally accurate in making predictions when compared with the GGA-based hydraulic solver.

AB  - Solution of the nonlinear system of equations describing the network hydraulics problem can be formulated in several different manners, yielding various methods of solution. The most popular formulation is probably the Global Gradient Algorithm (GGA). Loop-flow formulation is another method revisited by number of researchers in recent years. Loop-flow method has the smaller system matrix to solve, which is a benefit over the GGA’s matrix, coming from the fact that real networks typically have far less loops than nodes. However, need for cumbersome pre-processing to identify network loops and sparsity of solution matrix, which is highly dependent of implemented loop identification algorithm, remain key drawbacks of existing loop-flow methods. In addition, systematic testing on the real life networks of different topologies and complexities is still somewhat lacking in the literature. In this paper, new loop-flow type method based on the novel TRIangulation BAsed Loop identification algorithm (TRIBAL) coupled with efficient implementation of loop-flow based hydraulic solver (ΔQ) is presented. Performance of the new TRIBAL ΔQ method based solver is tested through the comparison with the reference GGA solver. Preliminary results show that significant calculation speedups can be achieved with proposed method, maintaining prediction accuracy and convergence of the reference solver.

AB  - This paper presents new algorithm for sectorisation of a Water Distribution Network (WDN) named Water Network Sectorisation (WNS) algorithm. Algorithm relies on Graph Theory to search for the Strong Connected Components (SCCs) in the graph, that are later on topologically sorted and aggregated in the sectors. Aggregation is driven by engineering criteria and heuristics such as sectors of approximately equal size with smallest number of links connecting them. Interventions in the network are not implemented in order to avoid negative effects on the networks' hydraulics. This is important especially for primary stages of sectorisation in which preserving hydraulic performance and minimal investment are the main objectives. Methodology is illustrated on a real size WDN. The results obtained show that the WNS algorithm can be used as an effective support tool in engineering practice.

AB  - The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of data acquired. Since real-time data is likely to contain a certain amount of anomalous values and data acquisition equipment is not perfect, it is essential to equip the SCADA (Supervisory Control and Data Acquisition) system with automatic procedures that can detect the related problems and assist the user in monitoring and managing the incoming data. A number of different anomaly detection techniques and methods exist and can be used with varying success. To improve the performance, these methods must be fine tuned according to crucial aspects of the process monitored and the contexts in which the data are classified. The aim of this paper is to explore if the data context classification and pre-processing techniques can be used to improve the anomaly detection methods, especially in fully automated systems. The methodology developed is tested on sets of real-life data, using different standard and experimental anomaly detection procedures including statistical, model-based and data-mining approaches. The results obtained clearly demonstrate the effectiveness of the suggested anomaly detection methodology.

AB  - The knowledge about hydraulic and hydrologic processes is based on the monitoring of environmental and technical systems where they take place. The result of monitoring are the data that can be transformed into some useful information and knowledge, but only if the level of data reliability and accuracy is known. A framework for data validation and check according some additional knowledge about observed processes is presented in this paper. The validation system is designed in a way that can be adjusted to different levels of data validation based on time when the validated data is needed (automatic, semi-automatic and manual) and on availability of additional data that can be used in validation process (technical characteristics of the monitoring system, experts knowledge about monitored process or existing relations between monitored variables). As a result of data validation, every data value is labeled with validation grade that shows how much the data value is representative for monitored hydraulic and hydrologic process.
AB  - Spoznaja o hidrotehničkim procesima potiče od osmatranja prirodnih i tehničkih sistema u kojima se odvijaju. Proizvod osmatranja su podaci koje je dalje moguće pretvoriti u korisne informacije i znanje, ali samo ako se zna koliko su ti podaci pouzdani i tačni. Cilj ovog rada je da predloži sistem po kome bi se mogla sprovesti validacija i provera prikupljenih podataka na osnovu prethodnog znanja o osmatranom hidrotehničkom procesu. Sistem je osmišljen tako da se može prilagoditi različitim nivoima validacije u pogledu vremena kada su potrebni validovani podaci (automatska, poluautomatska ili ručna validacija) kao i u pogledu raspoloživosti hidrotehničkih simulacionih modela i dodatnih informacija (tehničkih karakteristika sistema za osmatranje, ekspertskog znanja o osmatranom procesu ili relacije između merenih veličina). Rezultat validacije je ocena koliko je svaki podatak reprezentativan za osmatrani hidrotehnički proces.

AB  - The number of automated measuring and reporting systems used in water distribution and sewer systems is dramatically increasing and, as a consequence, so is the volume of acquired data. Since the real time data is likely to contain a certain amount of anomalous values and since the probability of equipment malfunction is high, it is essential to equip the SCADA with automatic procedures that will detect the problems and assist the user in monitoring and data management. A number of anomaly detection techniques and methods exist that can be used with varying success. Some of those techniques in some cases are applicable to the online usage (inspection of the incoming data streams) but usually are more suitable for the offline data processing since they require frequent expert's involvement in parameter adjustment. The aim of this paper is to explore the online and offline data pre-processing techniques that could be used to remove redundant information and reduce the total volume of acquired data whilst preserving all the necessary data series features that could be used for anomaly detections. The paper explores the usefulness of different pre-processing techniques as a tool for improving the anomaly detection methods. The methodology developed is tested on several sets of real-life data, with different anomaly detection procedures including statistical, model-based and data mining approaches. The results obtained demonstrate the effectiveness of the suggested methodology.
