Hydroinformatics systems are systems that combine computational hydraulic modelling with information systems (including knowledge-based systems). They are gaining rapid acceptance in the areas of environmental planning, design and management. The present book focuses exclusively on sewage systems, starting with their planning and then going on to discuss their design, operation and rehabilitation. The very experienced authors discuss business and information needs in the management of urban drainage, tools for collecting and archiving such data, and their use in modelling catchment hydrology, sewer systems hydraulics, wastewater quality, wastewater treatment plant operation, and receiving waters. The control and operation of sewer systems in real time is described, followed by a discussion of their maintenance and rehabilitation. Intelligent decision support systems for managing the urban drainage business process are presented. Audience: Researchers into sewer design, municipal engineers, planners and managers interested in an innovative approach to all aspects of the planning, design and operation of sewer systems.

This collection of papers is aimed at both the research community and the professional involved with water supply systems within the context of integrated urban water systems as a whole. Based on both field expertise and research results, this book offers a range of innovative techniques such as diagnostics, demand management, uncertainty analysis and transients models, alongside more traditional methods such as optimisation and network analysis, designed to enable the practitioner to devise the most sustainable and cost-effective solutions. Topics discussed include data management; management and detection of leakage; analysis, design and rehabilitation of distribution networks; water quality management; effectiveness of water conservation; water economics; consumption trends and demand forecast; specific country experiences with demand management.

Frontiers in Urban Water Management presents the state-of-the art in urban water management at the beginning of the 21st century. The book marks the end of the fifth phase of UNESCO's International Hydrological Programme in this field by bringing together major scientific and professional players to address critical and topical issues in water management. This team of leading world experts investigate themes such as the challenges of urban water management, infrastructure integration issues, and emerging paradigms in water supply and sanitation. Key issues are investigated from the hydrological, technical and managerial points of view, incorporating both social and economic realities. Specific reference is also made to solutions for developing countries. With a view to the future, conclusions from past experiences are highlighted, new pathways are explored and future developments are suggested. Contents The challenge of urban water management Urban water as a part of integrated catchment management Interactions with the environment Infrastructure integration issues Emerging paradigms in water supply and sanitation Problems of developing countries Economic and financial aspects Social, institutional and regulatory issues Outlook for the 21st Century

A collection of articles by leading international experts on modeling and control of potable water distribution and sewerage collection systems, focusing on advances in sensors, instrumentation and communications technologies; assessment of sensor reliability, accuracy and fitness; data management including SCADA and GIS; systems modelling, optimisation and decision support; real time monitoring, modelling control and associated uncertainties; water quality, water and wastewater treatment modeling; demand forecasting, leakage and energy management; asset management and performance modeling; sustainable urban water management including flooding issues; security, reliability and resilience of water systems; likely impacts of climate change; Water scarcity and intermittent supply. Intended for water researchers in industry and academia.

As we approach a historic tipping point in the global trend toward urbanisation - within two decades urban dwellers will increase from 49% to 60% of the planet's population - this book identifies and addresses a critical problem: water. The editors show how cities can shift from being water consumers to resource managers, applying urban water management principles to ensure access to water and sanitation infrastructure and services; manage rainwater, wastewater, storm water drainage, and runoff pollution; control waterborne diseases and epidemics; and reduce the risk of such water-related hazards as floods, droughts and landslides. The book explores the Multiple-Use Water Services (MUS) paradigm, offering a section on the MUS approach and a means of calculating the value of MUS systems, as well as tools and resources to support decision-making. Case studies illustrate MUS in selected urban and rural contexts. Each case study breaks out the challenges, policy framework, benefits, benchmarks, lessons learned (success and failures) and potential next steps. The contributors consider the main options for applying the Multiple-Use Water Services (MUS) paradigm, breaking down its components and offering cost-benefit analyses along with challenges and considerations for both the short and long term. Also discussed are methods by which mutual interactions of water infrastructure and vegetated areas are taken into account in the synergy of spatial planning and optimised modelling of ecosystems' performance indicators. This method of planning should make future developments cheaper to build; their users will pay lower utility bills for water, energy and heating. These developments will be more pleasant to live in and property value would likely be higher. The brief includes a section on the MUS approach and a means to calculate the value of MUS systems, as well as provides tools and resources to support decision-making. Case studies are included to illustrate MUS in selected urban and rural contexts. Each case study breaks out the challenges, policy framework, benefits, benchmarks, lessons learned (success and failures) and potential next steps.

Technology now affects almost every aspect of Water Supply Management, Operation, Planning and Design; the speed of development means that assessing what is "new" is sometimes difficult. Old ideas can now be applied because of new technology; technology is now revealing problems that were unnoticed 10 years ago. Some emerging technologies promise much but are still underdeveloped for use in real world conditions, while we should always remember that "new" technology depends upon the state of development in respective countries, a point which is particularly relevant to the NATO Advanced Study Institute, for which this book has been produced. Thus our objective in producing the book has been to highlight, in a wide range of technical areas, where and how technology is being applied, what is "new" and what the limitations of these technologies are in the real world. We have also tried to provide an European and American perspective where possible to illustrate how problems are tackled in different cultural environments. It is probably true that "technology" is also somewhat dependent upon the political, economic and organisational climate in different countries and we have included a chapter covering these aspects.
