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.

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.

Urban population growth dramatically alters material and energy fluxes in the affected areas, with concomitant changes in landscape, altered fluxes of water, sediment, chemicals and pathogens and increased releases of waste heat. These changes then impact on urban ecosystems, including water resources and result in their degradation. Such circumstances make the provision of water services to urban populations even more challenging. Changing weather patterns, rising temperature and large variations in precipitation contr- ute to increased damages, caused by weather related disasters, including floods. Ones of the major contributors to increasing flood peaks are land use changes and particularl- urban development. Consequently, there is a need to look for low environmental impact land development and to manage runoff in urban areas by storm water management. Much progress in the management of urban waters has been achieved in the most - vanced jurisdictions, but much more remains to be done. In this respect the EC Water Framework Directive can provide some guidance. Urban water management issues are particularly important in the countries in transition in Central and Eastern Europe. During the last decade political, economical and social changes in the countries under transition have influenced almost every element of the public sector, including water services. There is an urgent need for exchange of information among various countries on this issue and for identification of best approaches to achieving this transition.

A considerable amount of scientific evidence has been collected leading to the conclusion that urban wastewater components should be designed as one integrated system, in order to protect the receiving waters cost-effectively. Moreover, there is a need to optimize the design and operation of the sewerage network and wastewater treatment plant (WwTP) considering the dynamic interactions between them and the receiving waters. This book introduces a method called Model Based Design and Control (MoDeCo) for the optimum design and control of urban wastewater components. The book presents a detailed description of the integration of modelling tools for the sewer, the wastewater treatment plants and the rivers. The complex modelling structure used for the integrated model challenge previous applications of integrated modelling approaches presented in scientific literature. The combination of modelling tools and multi-objective evolutionary algorithms demonstrated in this book represent an excellent tool for designers and managers of urban wastewater infrastructure. This book also presents two alternatives to solve the computing demand of the optimization of integrated systems in practical applications: the use of surrogate modelling tools and the use of cloud computer infrastructure for parallel computing.

This comprehensive text provides the reader with both a detailed reference and a unified course on wastewater treatment. Aimed at scientists and engineers, it deals with the environmental and biological aspects of wastewater treatment and sludge disposal.The book starts by examining the nature of wastewaters and how they are oxidized in the natural environment. An introductory chapter deals with wastewater treatment systems and examines how natural principles have been harnessed by man to treat his own waste in specialist reactors. The role of organisms is considered by looking at kinetics, metabolism and the different types of micro-organisms involved. All the major biological process groups are examined in detail, in highly referenced chapters; they include fixed film reactors, activated sludge, stabilization ponds, anaerobic systems and vegetative processes. Sludge treatment and disposal is examined with particular reference to the environmental problems associated with the various disposal routes. A comprehensive chapter on public health looks at the important waterborne organisms associated with disease, as well as removal processes within treatment systems. Biotechnology has had an enormous impact on wastewater treatment at every level, and this is explored in terms of resource reuse, biological conversion processes and environmental protection. Finally, there is a short concluding chapter that looks at the sustainability of waste water treatment. The text is fully illustrated and supported by over 3000 references./a

by Professor Poul Harremoes Environmental engineering has been a discipline dominated by empirical approaches to engineering. Historically speaking, the development of urban drainage structures was very successful on the basis of pure empiricism. Just think of the impressive structures built by the Romans long before the discipline of hydraulics came into being. The fact is that the Romans did not know much about the theories of hydraulics, which were discovered as late as the mid-1800s. However, with the Renaissance came a new era. Astronomy (Galileos) and basic physics (Newton) started the scientific revolution and in the mid-1800s Navier and Stokes developed the application of Newtons laws to hydrodynamics, and later, St. Venant the first basic physics description of the motion of water in open channels. The combination of basic physical understanding of the phenomena involved in the flow of water in pipes and the experience gained by "trial and error", the engineering approach to urban drainage improved the design and performance of the engineering drainage infrastructure. However, due to the mathematical complications of the basic equations, solutions were available only to quite simple cases of practical significance until the introduction of new principles of calculation made possible by computers and their ability to crunch numbers. Now even intricate hydraulic phenomena can be simulated with a reasonable degree of confidence that the simulations are in agreement with performance in practice, if the models are adequately calibrated with sample performance data.
