Book Synopsis Sewer Networks and Processes within Urban Water Systems by : Jean-Luc Bertrand-Krajewski
Download or read book Sewer Networks and Processes within Urban Water Systems written by Jean-Luc Bertrand-Krajewski and published by IWA Publishing. This book was released on 2004-11-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume were originally presented at the 18th European Junior Scientists Workshop (EJSW), Portugal, on 8-11 November 2003 and at the 1st Asian Junior Scientists Workshop (AJSW), Malaysia, on 7-10 February 2004. The workshops were organised by the SS&PWG (Sewer Systems and Processes Working Group) of the IWA/IAHR Joint Committee on Urban Drainage. The two separate workshops were convened under the general themes of "Sewer Processes, Networks and Urban Drainage" and specific topics covered included integrated modelling of urban water systems; modelling of pollutant loads; calibration of models; bed-load transport; sewer pipe roughness; advection in sewers; anoxic processes; infiltration and exfiltration; runoff source control; pollutant loads; ventilation and oxygen uptake. From the 37 full papers presented at the two workshops, 16 papers have been selected by independent reviewers from the SS&PWG for publication in Sewer Networks and Processes within Urban Water Systems. They reflect rather well the variety of topics presented during both workshops, and bring the high-quality work of these junior authors to the wider audience it merits.
Book Synopsis Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems by : Bryan Ellis
Download or read book Assessing Infiltration and Exfiltration on the Performance of Urban Sewer Systems written by Bryan Ellis and published by IWA Publishing. This book was released on 2010-02-10 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sewer systems constitute a very significant heritage in European cities. Their structural quality and functional efficiency are key parameters to guarantee the transfer of domestic and industrial wastewater to treatment plants without infiltration nor exfiltration. Infiltration of groundwater is particularly detrimental to treatment plant efficiency, while exfiltration of wastewater can lead to groundwater contamination. The European research project APUSS (Assessing infiltration and exfiltration on the Performance of Urban Sewer Systems) was devoted to sewer infiltration and exfiltration questions. It was structured in three main Work Areas dealing respectively with i) the development of new measurement methods based on tracer experiments and accounting for detailed uncertainty analyses, ii) the implementation of models and software tools to integrate structural and experimental data and to facilitate data display, operational management and decision-making processes and iii) the integration of economic and operational questions by means of cost estimation, economic evaluation, performance indicators and multi-criteria methods applied to investment/rehabilitation strategies. This final report describes the objectives, methods and main results for each Work Area. References to detailed methods, protocols, reports and tools are given in this final report which will be an invaluable source of information for all those concerned with the performance of urban sewer systems.
Book Synopsis Privatization of Water Services in the United States by : National Research Council
Download or read book Privatization of Water Services in the United States written by National Research Council and published by National Academies Press. This book was released on 2002-08-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

The authors add chemical and microbial dimensions to the design and management of sewer networks with an overall aim of improved sustainability for the system itself and the surrounding environment.
Book Synopsis Optimal Real-time Control of Sewer Networks by : Magdalene Marinaki
Download or read book Optimal Real-time Control of Sewer Networks written by Magdalene Marinaki and published by Springer Science & Business Media. This book was released on 2005-12-02 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sine qua non of control system development for modern sewer networks is the preservation of the water system around a network’s outflow(s). Several approaches have been proposed for the optimisation of sewage control and Optimal Real-time Control of Sewer Networks provides a comparative synthesis of a central sewer network flow control based on two of these: nonlinear-optimal and multivariable-feedback control. Testing and comparison of these protocols are made on the basis of their control results for the large-scale sewer network located around the river Obere Iller in Bavaria. The control strategies implemented within this network are based on this study. From the selection of possible methods of control and moving to the implementation of those methods in a real sewer system, this monograph will be invaluable to control and civil engineers working in sewage flow and wastewater treatment and of interest to academics wishing to see how their ideas on optimal control work out when practically applied.
Download or read book Urban Water II written by S. Mambretti and published by WIT Press. This book was released on 2014-05-27 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Water II is the proceedings of the 2nd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems. The meeting was reconvened following the success of the first conference held in the New Forest, home to the Wessex Institute of Technology in 2012. Water systems in the urban environment consist of supply networks as well as sewage and storm drainage systems. They interact with each other and with warm bodies such as rivers, lakes and aquifers, and this interaction affects the quality and quantity of the different systems. As our cities continue to expand, their urban infrastructure must be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanisation. New water systems are also required to reduce the risk associated with floods, network failures and many others related to inadequate networks. New systems should reduce economic losses and environmental impacts as well as promote a higher degree of reliability. Improved management, measurement and control mechanisms are needed to ensure the efficiency and safety of urban water systems. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Architects and town planners are also aware of the importance of the interaction between urban water cycles and city planning and landscaping. Management of all these aspects requires the development of specialised computer tools that can respond to the increased complexity of urban water systems. Relating to the subject areas of Water supply networks and Urban Drainage, topics covered include: Leakage and losses; Modelling and experimentation; Safety and security of water systems; Maintenance and repairs; Water quality; Water savings and reuse; Surface water and groundwater sources; Reservoirs; Network design; Waste water treatment and disposal; Structural works and infrastructure; Water quality issues; Combined sewer networks; Flood control; Storage tanks; Environmental impact; Domestic and industrial waste water issues.

Download or read book Mathematical Modelling and Computer Simulation of Activated Sludge Systems written by Jacek Makinia and published by IWA Publishing. This book was released on 2020-03-02 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Modelling and Computer Simulation of Activated Sludge Systems – Second Edition provides, from the process engineering perspective, a comprehensive and up-to-date overview regarding various aspects of the mechanistic (“white box”) modelling and simulation of advanced activated sludge systems performing biological nutrient removal. In the new edition of the book, a special focus is given to nitrogen removal and the latest developments in modelling the innovative nitrogen removal processes. Furthermore, a new section on micropollutant removal has been added. The focus of modelling has been shifting in the last years to models that can describe the performance of a whole plant (plant-wide modelling). The expanded part of this new edition introduces models describing the most important processes interrelated with the mainstream activated sludge systems as well as models describing the energy balance, operating costs and environmental impact. The complex process evaluation, including minimization of energy consumption and carbon footprint, is in line with the present and future wastewater treatment goals. By combining a general introduction and a textbook, this book serves both intermediate and more experienced model users, both researchers and practitioners, as a comprehensive guide to modelling and simulation studies. The book can be used as a supplemental material at graduate and post-graduate levels of wastewater engineering/modelling courses.

Book Synopsis INTERURBA II Interactions Between Sewers, Treatment Plants and Receiving Waters by : J. Saldanha Matos
Download or read book INTERURBA II Interactions Between Sewers, Treatment Plants and Receiving Waters written by J. Saldanha Matos and published by IWA Publishing (International Water Assoc). This book was released on 2002-05-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the decade since the first INTERURBA conference (Wageningen 1992) the power of the integrated approach to address pollution control and the preservation or enhancement of receiving waters in urban areas has been ever more widely recognised. There have also been significant advances in understanding the interactions between urban drainage systems and sewage treatment plants and the influence of contaminants from different sources on receiving waters. New ideas have been developed, for instance, applying process models for receiving waters and sewer systems together with established models for wastewater treatment processes, and ecologically sustainable wastewater systems and best management practices for wastewater systems (sewer systems and receiving waters or soil). The objective of INTERURBA II was to bring together scientists and practising engineers from five continents, the leading figures in the areas of environmental management and control, to discuss the physical, chemical and biological processes and their interactions within the urban water cycle, with the aim of reaching a common understanding, which in turn could lead to development of guidelines on the integrated management of sewers, treatment plants and receiving ecosystems. A significant number of papers gave special emphasis to one of the components within the integrated system, especially to the sewer. This issue contains a selection of 31 papers presented at INTERURBA II. They have been divided into the following four themes: in-sewer processes and effects on treatment plants and/or receiving waters; mathematical modelling of integrated systems; management practices of urban basins and sustainability of wastewater systems; and operation of sewer systems and treatment plants. Together they constitute a major step towards the consolidation of the new framework for urban water management.
Book Synopsis Smart Water Utilities by : Pernille Ingildsen
Download or read book Smart Water Utilities written by Pernille Ingildsen and published by IWA Publishing. This book was released on 2016-05-15 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today there is increasing pressure on the water infrastructure and although unsustainable water extraction and wastewater handling can continue for a while, at some point water needs to be managed in a way that is sustainable in the long-term. We need to handle water utilities “smarter”. New and effective tools and technologies are becoming available at an affordable cost and these technologies are steadily changing water infrastructure options. The quality and robustness of sensors are increasing rapidly and their reliability makes the automatic handling of critical processes viable. Online and real-time control means safer and more effective operation. The combination of better sensors and new water treatment technologies is a strong enabler for decentralised and diversified water treatment. Plants can be run with a minimum of personnel attendance. In the future, thousands of sensors in the water utility cycle will handle all the complexity in an effective way. Smart Water Utilities: Complexity Made Simple provides a framework for Smart Water Utilities based on an M-A-D (Measurement-Analysis-Decision). This enables the organisation and implementation of “Smart” in a water utility by providing an overview of supporting technologies and methods. The book presents an introduction to methods and tools, providing a perspective of what can and could be achieved. It provides a toolbox for all water challenges and is essential reading for the Water Utility Manager, Engineer and Director and for Consultants, Designers and Researchers.
Book Synopsis Urban Water Resources Toolbox by : Leif Wolf
Download or read book Urban Water Resources Toolbox written by Leif Wolf and published by IWA Publishing. This book was released on 2007-01-19 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Holistic but applicable approaches are urgently needed to help plan long-term, cost-effective and sustainable urban water management systems. Groundwater is a central element in the urban water cycle of all cities located on aquifers, yet it remains inadequately integrated into urban water management practices. This book describes holistic approaches for quantification and balancing of urban water and solute fluxes that have been developed by the joint Euro-Australian research project AISUWRS. The new tools comprise a chain of interconnected models that link urban water supply, urban drainage and urban groundwater resources. These include a new sewer exfiltration, model that is based on pipe asset conditions which permits flows to the environment to be estimated. The book provides details on the further processing of this information through the unsaturated zone down to aquifer, where numerical groundwater flow and transport models are applied. Concise documentation is provided on each of the models. The practicability of applying the chain of models was tested by applying it in four case study cities in Australia, Germany, Slovenia and the United Kingdom that have diverse conditions in terms of hydrogeologic setup, climate and data availability. This permitted additional validation by field investigations, including problem-oriented monitoring campaigns aimed at assessing the impact of wastewater practice on groundwater. The book provides guidance and examples of the application of multilevel piezometers, on adapted monitoring strategies, and the use for interpretation purposes of microbiological parameters, pharmaceutical residues and related marker species. The socio-economic analysis in the case study cities sometimes uncovered distinctively different problem perceptions and priorities, both in the groups of experts responsible for the water management and with the remaining stakeholders. The AISUWRS project has developed tools to foster these urgently required deliberation processes. Methodologies for formal sustainability assessment with a triple bottom line background were also elaborated and tested during the case studies. The case studies have shown that the approach is valid and constitutes an important step towards integrated urban water management.
Book Synopsis Sewer Processes and Networks by : Jean-Luc Bertrand-Krajewski
Download or read book Sewer Processes and Networks written by Jean-Luc Bertrand-Krajewski and published by IWA Publishing. This book was released on 2003-01-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wastewater, biofilms and sediments in sewers are subject to important physical, chemical and microbial changes and interactions affecting not only the sewer itself but also the subsequent wastewater treatment and receiving waters via combined sewer overflows or separate sewer outfalls. This was a motivating theme behind two previous conferences (published in Water Science and Technology) on ?The sewer as a physical, chemical and biological reactor?. This third conference, building on its predecessors, aimed to bring together scientists and practising engineers in the area of environmental process engineering and management of sewer systems to present their results and discuss physical, chemical and biological processes in sewers, and related structural aspects of sewer systems. Key topics covered included: interactions between sewers and the urban wastewater system including wastewater treatment, combined sewer overflows and receiving waters; characterisation, processes and physical interactions of sewer biofilm, sediments, wastewater and air; microbial and chemical processes; solutes and sediments transport including sedimentation and erosion; sulphide formation, corrosion and odour problems; bacteriology; specific pollutants; design, operation and control related to sewer processes; and interactions between sewer structure and processes. From the 45 available papers, 22 have been selected, reviewed and revised for publication in this issue, which reflects the most important aspects of the conference. Together they are a major step towards a more comprehensive and multidisciplinary understanding of sewer behaviour and functioning, of prime importance for the design, operation and upgrading of urban sewer and wastewater systems.
