  • Modeling trihalomethane formation for Jabal Amman water supply in Jordan

    A mathematical model that expresses Total trihalomethane (TTHM) concentration in terms of initial chlorine concentration, total organic carbon, bromide ion concentration, contact time, and pH is developed for Zai water treatment plant which supplies water to Jabal Amman. The developed mathematical model is for constant temperature of 20°C. To adjust model calculated TTHM concentrations for ...

  • An evaluation model for measuring customer satisfaction levels in a water supply domain: case study – water supply in Hamedan

    Customer satisfaction is an important goal in total quality management. In order to meet this goal, it is necessary to use an evaluation model to measure customer satisfaction. This paper proposes an evaluation model for measuring the customer satisfaction level in a water supply domain. Some important criteria such as water quality, water quantity, responsibility of the company, etc. are ...

  • Homeland Security for Drinking Water Supplies

    As it has done with other jurisdictions, Congress has recently passed legislation aimed at protecting our nation's drinking water resources. Historically, water supply protection has been a high priority, including reservoir protection, continuous monitoring, and secure and redundant facilities to ensure an uninterrupted supply of drinking water. The Clean Water Act (1972), requires pollution ...

  • Structural equation modeling for assessing of the sustainability of rural water supply systems

    As one of the basic human needs, water services should be sustainable. Researches related to the sustainability of water services have been conducted in several developing countries. However, there are no identical researches in Indonesia. This paper discusses the analysis of factors that contribute to sustainability of rural water supply systems in East Java, Indonesia. Data is collected by ...

  • Improving equity in intermittent water supply systems

    The problems of limited financial resources and water scarcity in urban areas of developing countries are of concern to water managers following growing demand–supply imbalance. As a result, an intermittent supply is widely adopted as a measure for controlling water demand among consumers. However, ensuring equitable water distribution at low cost in intermittent water supply systems ...

  • Identifying water quality monitoring stations in a water supply system

    Despite good quality assurance and conformance to the standards at the treatment plants, water quality could vary considerably within the distribution network. As water flows through the pipe network, its quality undergoes various transformations due to many factors such as the properties of the finished water, pipe materials, water temperature, water age and low level of disinfectant residuals. ...

  • Simulating development strategies for water supply systems

    ABSTRACT The objective of this paper is to point out existing risks of current design and management strategies in water supply systems and to identify possible ways of designing and operating schemes which minimize these risks. This paper is motivated by the observation that existing design principles and engineering rules (best practice) seem to cope insufficiently or even conflict with ...

  • Implementation of pressure reduction valves in a dynamic water distribution numerical model to control the inequality in water supply

    The analysis of water distribution networks has to take into account the variability of users' water demand and the variability of network boundary conditions. In complex systems, e.g. those characterized by the presence of local private tanks and intermittent distribution, this variability suggests the use of dynamic models that are able to evaluate the rapid variability of pressures and ...

  • Water supply in Jordan under drought conditions

    This paper discusses the Mujib Dam reservoir's storage during the drought years of 2007–2009. It has been concluded that the policy of unplanned water release during the dry year 2007, when little attention was paid to the possibility of a continuation of the drought, contributed to the remarkable lack of surface water storage during 2008, another dry year. For better management and planning, ...

  • Integrated hydraulic modelling of water supply and urban drainage networks for assessment of decentralized options

    The impact of climate change, water scarcity, land use change, population growth and also population shrinking can only be predicted with uncertainties. Especially for assets with a long planning horizon this is a critical part for planning and design. One solution is to make centralized organized water infrastructure with a long-planning horizon resilient and adaptive. For existing centralized ...

  • Pressure transfer modeling for an urban water supply system based on Pearson correlation analysis

    This paper presents an approach to modeling the water pressure transfer among nodes in an urban water supply network for the purpose of pressure control. The network is divided into different sub-networks based on the Pearson correlation analysis of the nodal pressure measurements. The Pearson correlation analysis is performed to find out the set of nodes, whose water pressures are highly ...

  • Assessing measurement uncertainty on trihalomethanes prediction through kinetic models in water supply systems

    Disinfection of drinking water through chlorine is commonly used in many countries for reducing pathogenic infection problems, but it may pose a risk to human health due to the formation of some by-products, such as trihalomethanes (THMs). For an adequate management of the disinfection process, it is useful to have models capable of simulating THMs concentrations in water supply systems. ...

  • Influence of intermittent water supply operations on the vulnerability of water distribution networks

    Water authorities in countries facing water shortage problems are implementing intermittent water supply (IWS) policies, as a measure to conserve and control their national water resources. Implementation of such measures affects the behaviour of the water pipe systems during the operation stage. The research work presented herein presents a model simulating the behaviour of urban water ...

  • Model- vs. data-based approaches applied to fault diagnosis in potable water supply networks

    The problem of fault diagnosis in potable water supply networks is addressed in this paper. Two different fault diagnosis approaches are proposed to deal with this problem. The first one is based on a model-based approach exploiting a priori information regarding physical/temporal relations existing among the measured variables in the monitored system, providing fault detection and isolation ...

  • Return of drinking water supply in Paris to public control

    The ‘reclaiming’ by Paris of its water back into public hands is a paradox in the homeland of transnational water companies and at a time when the European Commission rather favours the liberalisation of public services ‘of general economic interest’. Yet what has happened is more complex. A quick historical review of management formulas in Europe reveals both the ...

  • Water and energy futures for Melbourne: implications of land use, water use, and water supply strategy

    This paper quantifies the effect of three policy levels on the water and energy futures of Melbourne, Australia. During a time of severe water shortages attributed to climate change, water strategies lacked consideration of energy consequences. Modeling, guided by urban metabolism theory, demonstrated that a compact urban form, reduced water consumption by 90 GL/a, compared with a sprawling ...
