Water Supply Network District Metering by Armando Di Nardo,Michele Di Natale,Anna Di Mauro Pdf

The management of a water supply network can be substantially improved defining permanent sectors or districts that enhances simpler water loss detection and pressure management. However, the water network partitioning may compromise water system performance, since some pipes are usually closed to delimit districts in order not to have too many metering stations, to decrease costs and simplify water balance. This may reduce the reliability of the whole system and not guarantee the delivery of water at the different network nodes. In practical applications, the design of districts or sectors is generally based on empirical approaches or on limited field experiences. The book proposes a design support methodology, based on graph theory principles and tested on real case study. The described methodology can help water utilities, professionals and researchers to define the optimal districts or sectors of a water supply network.

Improving Water Supply Networks: Fit for Purpose Strategies and Technologies by Stuart Hamilton,Bambos Charalambous,Gary Wyeth Pdf

Knowing how to manage the losses from water supply networks and how to get to the next level in bettering your system is a major problem and one that is most common in the majority of water companies worldwide. Sometimes water companies set their sights too high and cannot deliver due to non-realistic targets setting. Of course this is considered or seen as a failure within the company or country when it is really just exceeding expectations of what can be delivered. The aim of System Losses from Water Supply Networks is to assist water companies to identify where they are on the ‘water loss ladder’ and what is required to move to the next level. The book will provide an understanding of what the water companies need to achieve and where they should be aiming for in their efforts to reduce water losses. The book provides useful and practical information on non-revenue water (NRW) issues and solutions enriched with relevant case studies.

Environmental Engineering V by Malgorzata Pawlowska,Lucjan Pawlowski Pdf

Poland, like other post-communist countries, is undergoing a transformation into a capitalist system. This transformation affects the country in many ways: economic, social, psychological and also ecological. Ecological problems are strongly connected with the political, economic and psychological inheritance of the past, as well as with changes in the post-communist society. In order to understand these problems, it is necessary to consider the following issues: - the geographic situation of Poland - the political transformations that occurred after World War II – forced development of heavy industry combined with neglect of its effects on the environment, and - the economic problems The three main goals of Environmental Engineering V are (I) to assess the state of scientific research in various areas of environmental engineering. (II) to evaluate organizational, technical and technological progress in contributing to ecological security, and (III) to determine the place of environmental engineering in sustainable development, taking into account political and economic conditions. Environmental Engineering V is of interest for academics, engineers and professionals involved in environmental engineering, seeking solutions for environmental problems in emerging new democracies, especially those who plan to participate in numerous projects sponsored by the European Union.

Advances in Modeling and Management of Urban Water Networks by Alberto Campisano,Enrico Creaco Pdf

The Special Issue on Advances in Modeling and Management of Urban Water Networks (UWNs) explores four important topics of research in the context of UWNs: asset management, modeling of demand and hydraulics, energy recovery, and pipe burst identification and leakage reduction. In the first topic, the multi-objective optimization of interventions on the network is presented to find trade-off solutions between costs and efficiency. In the second topic, methodologies are presented to simulate and predict demand and to simulate network behavior in emergency scenarios. In the third topic, a methodology is presented for the multi-objective optimization of pump-as-turbine (PAT) installation sites in transmission mains. In the fourth topic, methodologies for pipe burst identification and leakage reduction are presented. As for the urban drainage systems (UDSs), the two explored topics are asset management, with a system upgrade to reduce flooding, and modeling of flow and water quality, with analyses on the transition from surface to pressurized flow, impact of water use reduction on the operation of UDSs, and sediment transport in pressurized pipes. The Special Issue also includes one paper dealing with the hydraulic modeling of an urban river with a complex cross-section.

Water Loss Assessment in Distribution Networks by Taha M. Al-Washali Pdf

Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.

Sustainable Water Resources Management XI by S. Mambretti Pdf

Papers presented at the 11th International Conference on Sustainable Water Resources Management are included in this volume. These research works highlight recent technological and scientific developments associated with the management of surface and sub-surface water resources and as well as river basin management methodologies. Water is essential for sustaining life on our planet and its uneven distribution is a source of permanent conflict. The growth of the human population combined with the irregularity in precipitation and water availability may restrict even further the access to water in certain regions of the world. This problem is made more severe by anthropogenic activities that affect its quality. River Basin Management includes all aspects of Hydrology, Ecology, Environmental Management, Flood Plains and Wetlands. Riverine systems are coming under increasing pressure due to anthropological and natural causes. Prominent amongst the problems affecting them is water scarcity and quality, which requires the development of improved methods for better river management. This volume features research from professionals involved in sustainable water resources management and provides an insight into the state of the art in the current technology, techniques and solutions in that field as they have been developed and applied in different countries.

Residential Water Demand by Angelo P. Grima Pdf

This detailed study of the use of water at different price levels by residential consumers in the Toronto-centred region from Hamilton to Oshawa challenges the basis of our present urban water supply policy. Adoption of the recommendations presented would mean higher prices to householders, but a considerable saving of hundreds of millions of tax dollars over the next three decades. The present policy uses a 'requirement approach' in which future water needs are calculated by extrapolation of past trends and an assumption that demand is inelastic. This leads to excessive levels of water use and over-investment in water supply, sewage collection, and treatment systems. The resultant misallocation of resources can be corrected by adoption of a demand/management approach in which investment policy is guided by consumer demand and alternative pricing arrangements are used as a management tool. Dr. Grima examines several alternative choices for management, such as metering, increasing marginal prices, sewerage charges, seasonal charges, and an increasing price block schedule, and describes the results of each. Water managers in Canada are strongly challenged to begin a fundamental rethinking of their basic policies. (Department of Geography Research Publication 7)
