Preface This book is the result of 5 years of research and more than 10 years of practical experience in urban wastewater infrastructure and their impacts in the receiving rivers. The motivation of the topic came with the experience gained in projects were urban wastewater systems were analyzed separately. Even though we understood the importance of the interaction between components, the knowledge and tools were not available to put this in practical applications. This book gives substantial

... idence of the importance of the integrated management of urban wastewater systems, if the protection of the receiving waters is to be achieved costeffectively. This new way of thinking, that considers the dynamic interaction between components, was tested in the design and operation of sewerage networks and wastewater treatment plants (WwTP). This book introduces a method named Model Based Design and Control (MoDeCo) for the optimum design of urban wastewater components. MoDeCo combines the traditional design approach with integrated modelling tools and multi-objective optimization algorithms. This book presents a detailed description of the modelling tools developed. Readers can learn to analyze data and implement an integrated model of the urban wastewater system by following the two case studies presented. This book also presents two alternatives to solve the problem of computing demand in optimization of urban wastewater systems: the use of surrogate modelling tools and the use of Cloud computer infrastmcture for parallel computing. The integrated modelling tools and multi-objective evolutionary algorithms given in this book are excellent tools for researchers and practitioners interested in planning and development of urban wastewater infrastructure. This book aims to help practitioners to optimize the design and operation of urban wastewater systems not only by reducing the cost of the infrastructure but also the risk of flooding and the pollution impacts.
