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 provides critique comprehensive summary current knowledge, policies challenges regarding research presents findings from survey international stakeholders....
The purpose of the research is to assess chlorine concentration in WDS using statistical models based on ANN combination with Monte-Carlo. This approach offers advantages contrast generally use methods for modeling decay drinking water systems until now. model was tested one specific location hydraulic and quality parameters such as flow, pH, temperature, etc. allows forecasting at selected nodes supply system. results obtained these allow then compare EPANET system under assessment.
CARE-W was a joint European initiative to develop framework for water network rehabilitation. The project supported by the Commission under Fifth Framework Programme Research and Development.The aim of support companies in their decisions on upgrading supply. system has been developed tested cities representing all parts Europe.CARE-W consists software dealing with fundamental instruments estimating current future condition networks, including tools assess performance indicators (PI),...
The paper presents the methodology for determining operating and technical indicators a preliminary assessment of elements water supply system (WSS) such as treatment plants. necessary data (TI) evaluation using multi-objective optimization Failure Mode Effects Analysis (FMEA) are defined. proposed allows selection ranking WSS critical more detailed analyses suggestions type renewal, including estimated financial costs. Water plants can be assessed by means specific part methodology. With...
To ensure sustainability and reliability of water supply infrastructure, we must apply a basic pre-condition, which is, its continual renewal. For renewal planning, there are many methods, techniques software tools for decision support, but most them, in cases, focus only on mains. Water systems, however, consist different parts structures than just pipes. It is therefore not appropriate to invest the planning relation one part infrastructure. The knowledge current technical condition...
The knowledge of the technical condition water distribution systems (WDS) is a key issue to predict performance WDS and optimize maintenance rehabilitation WDS. Common practice employs only practitioner experience assess presented paper summarizes basic theory indirect assessment including several definitions assessment, factors contributing deterioration possible outputs assessment. Furthermore, legal requirements concerning this specifically in Czech Republic Slovak are listed. There also...
Pressure management is the basic step of reducing water losses from supply systems (WSSs). The reduction direct reliably achieved by pressure in WSSs. There also a slight decrease consumption connected properties. Nevertheless, affected other factors, quantification which not trivial. However, there still lack much relevant information to enter into this analysis and subsequent decision making. This article focuses on its prediction, using regression models designed for an experiment...
The paper deals with auditing the technical condition of Water Distribution Systems (WDS) and its individual elements. presents methodology determining operating indicators (TI) for a preliminary assessment elements WDS (pumping stations, water tanks, transmission mains, distribution networks) implementation in two pumping necessary data system TI evaluation using multi-objective optimisation FMEA method. proposed allows selection ranking critical more detailed analysis suggestions type...
The project CARE-W presented in this paper deals with the public water supply networks and their problems of ageing such as structural failures, hydraulic insufficiencies, leakage, deteriorating quality increasing maintenance cost that impact on an urban environment. ultimate goal is to develop a suite tools, which provide most cost-efficient system repair distribution networks, aim guarantee security meets social, health, economic environmental requirements. comprises description...
This paper deals with a comparative analysis and benchmarking of drinking water supply systems sector in the selected countries Central Eastern Europe. These include Czech Republic, Poland, Romania, Slovakia. The article provides an existing each country. Methods supervision control over assessment functioning organizations responsible for utilities are also described. Comparative performance indicators is carried out. units, methods data collection processing were
The article presents in detail a proposed methodology for ILI estimation based on the analysis and measurement of minimum nighttime flow, along with results application methodology. responds to EU directive referred below.
The paper focuses on the issue of drinking water supply without use any disinfectants. Before public network operator begins to consider switching operation chemical disinfection, initial assessment should be made, whether or not system in question is suitable for this type operation. performed by applying decision algorithm. followed another algorithm which serves managing and controlling process a disinfectant. also summarizes previous experience knowledge way operated systems Czech Republic.
Abstract To ensure the sustainability and reliability of water supply infrastructure, a basic pre-condition must be applied related to its continual renewal. For renewal planning, there are number methods, techniques software tools for decision-support, but in many cases most them focus only on mains. However, systems consist more various parts structures than simply pipes. Therefore, it is not appropriate invest planning single part infrastructure only. An effective detailed evaluation...
The paper presents results and sensitivity analysis of the a real detailed study focused on changes in water consumption its unevenness with changing pressure conditions particular observed office building. dependence is expressed using FAVAD equation N3 coefficient. Parameters for are number workers building, pulse value from meter length time step expressing during day.
This paper outlines one possible approach to the comprehensive technical audit of water distribution networks. Based on practical experience, discussions with domestic and foreign operators, knowledge gained from international projects, proposes indicators, methods for their determination criteria evaluating values reached by these indicators. The proposed procedure is based FMEA (Failure Modes Effects Analysis) method, used in general theory risk analysis. results this method were employed...
This article deals with sensitivity analysis of real water consumption in an office building. During a long-term study, reducing pressure its connection was simulated. A uneven demand conducted during working time at various provided pressures and step duration. Correlations between maximal coefficients variation were suggested. The influence the on mean pointed out, altogether for hours all days separately identical hours.
The knowledge of the current technical condition operated system is in interest owner or operator public water supply systems. Such information starting point when making decisions on investment projects planning mains renewal. submitted paper introduces methodology preliminary assessment systems and outputs software application TEA Water, which makes it possible to assess specific elements clear displaying with presentation results for entire considered system.
This paper presents a comprehensive method for assessing the technical condition of water treatment plants as part set procedures entire supply system. The proposed plant assessment is based on system indicators and factors. Based these, carried out two-stage process, where evaluator first determines discrete values point score given to these factors then aggregated used calculate individual indicators, indicating overall plant. therefore includes two types indicators: structural–technical...
The article deals with the optimization of pressure conditions in public water supply systems. By reducing system, reduce direct losses from system will be reliably achieved, on other hand there is also a slight decrease consumption connected properties. Consumption possible to divide into two parts that are and non-pressure dependent consumption. quantification impact reduction not trivial. In order achieve optimal it necessary consider what should achieved outcome so as an economic optimum...
