  • This book incorporates selected topics on theory, revision, and practical application models for water supply systems analysis. A water supply system is an interconnected collection of sources, pipes, and hydraulic control elements (e.g., pumps, valves, regulators, tanks) delivering consumers prescribed water quantities at desired pressures and water qualities. Such systems are often described as a graph, with the links representing the pipes, and the nodes defining connections between pipes, hydraulic control elements, consumers, and sources.

  • After many years of studying microbiology, biofilms, and public health, it became my ambition to produce a book on these three areas. Having researched substantially into the formation and development of biofilms, particularly in potable water, I felt a book that could consolidate all the information on their public health significance was needed. This book provides a snapshot of public health and water with an appreciation of what a biofilm is and how well it presents a safe haven for pathogens, while factorizing unreported and reported water-related diseases....

  • As a matter of fact in some countries, mainly in India, groundwater development is much more important than surface water irrigation (Mukherji et al. 2009). While rainfed crops depend only on meteorological conditions, irrigated crops depend both on rain regimes and water supply. The combination of these regimes and the interdependencies between international commodity markets and domestic production create opportunities to ensure that water is allocated to the most valuable ends.

  • The objective of this study is to assist public authorities to identify and address the future challenges of urban water supply, sanitation, and flood management in cities. In order to do that, this report uses the conceptual framework of Integrated Urban Water Management (IUWM) as a holistic set of planning and management tools incorporating all components of the urban water cycle to help develop efficient and flexible urban water systems in the future. The future of water in African cities: why waste water? argues that a new approach to urban water management is needed in Africa.

  • The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues....
