  • 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.

  • Water supply and sanitation are amongst the most basic requirements of life. For the past 50 to 150 years people living in Europe, America and a few capital cities elsewhere around the globe have come to take for granted the provision of a virtually limitless supply of clean, safe water and the seemingly effortless removal of all human wastes ‘out of sight and out of mind’.

  • 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.

  • This meant that the plants were doing little in the beginning to clean the inflow. In the beginning it was not known if the plants would survive such a harsh environment. But after five months the plants have proven that they are a plant well designed for this environment. Some benefits about these plants are that they produce no seed, have no rhizomes, and can only reproduce by physically moving a piece of the plant. At five months, the plants are three feet in height and the root systems are now reaching the bottom of...

  • 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....

  • As the global population grows and many developing countries modernize, the importance of water supply and water treatment becomes a much greater factor in the welfare of nations. In similar fashion, the need to address both domestic and industrial wastes generated by these nations moves higher on the scale of importance. Clearly, in today’s world the competition for water resources coupled with the unfortunate commingling of wastewater discharges with freshwater supplies creates additional pressure on treatment systems....

  • In most HVAC systems, the final energy transport medium is moist air—a mixture of dry air and water vapor. This is conveyed through filters, heat exchange equipment, ducts, and various terminal devices to the space to be air-conditioned. The power to move the air is supplied by fans. This chapter discusses fans and duct systems, together with related subjects such as grilles, registers, diffusers, dampers, filters, and noise control.

  • Compared to other ecosystems, wetlands have received an exceptional amount of attention. Wetlands are valuable as sources, sink and transformers of a multitude of chemical, biological and genetic materials. They stabilize water supplies, clean polluted waters, protect shorelines, and recharge groundwater aquifers. They have increasingly become recognized for their unique ecological functions in the environment and are the focus of increased research by scientists and study programs by schools, communities, and nature centers.

  • The water problems in Asia’s cities are similar. These include sources and uses of raw water, the large propor-tion of water loss in distribution networks, intermittent supply, and the quality of tap water. In some cities, the excessive use of groundwater resources has caused serious environmental problems, including rapid deple-tion of groundwater, deterioration of water quality, and land subsidence.
