Book Description
In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.

Book Description
The reality of the post-September 11 situation forces the operators of water supply systems through the world to examine the security and safety of their systems, its vulnerability to intentional interference and sabotage with respect to quantity and quality of potable water. In assessing system vulnerability, there is an urgent need to develop emergency response plans providing ways and means for alternative water supply at the moment of system operation disruption, and system remediation and recovery after the attack. Security of Water Supply Systems: from Source to Tap presents the state-of-the art with a view to the future, conclusions from past experiences are highlighted and future developments are suggested in the field of drinking water safety.

Book Description
This text series of Water and Wastewater Engineering have been written in a time of mounting urbanisation and industrialisation and resulting stress on water and wastewater systems. Clean and ample sources of water for municipal uses are becoming harder to find and more expensive to develop. The text is comprehensive and covers all aspects of water supply, water sources, water distribution, sanitary sewerage and urban stormwater drainage. This wide coverage is helpful to engineers in their every day practice.

Book Description
Most of the technological developments relevant to water supply and wastewater date back to more than to five thousand years ago. These developments were driven by the necessity to make efficient use of natural resources, to make civilizations more resistant to destructive natural elements, and to improve the standards of life, both at public and private level. Rapid technological progress in the 20th century created a disregard for past sanitation and wastewater and stormwater technologies that were considered to be far behind the present ones. A great deal of unresolved problems in the developing world related to the wastewater management principles, such as the decentralization of the processes, the durability of the water projects, the cost effectiveness, and sustainability issues, such as protection from floods and droughts were intensified to an unprecedented degree. New problems have arisen such as the contamination of surface and groundwater. Naturally, intensification of unresolved problems has led to the reconsideration of successful past achievements. This retrospective view, based on archaeological, historical, and technical evidence, has shown two things: the similarity of physicochemical and biological principles with the present ones and the advanced level of wastewater engineering and management practices. Evolution of Sanitation and Wastewater Technologies through the Centuries presents and discusses the major achievements in the scientific fields of sanitation and hygienic water use systems throughout the millennia, and compares the water technological developments in several civilizations. It provides valuable insights into ancient wastewater and stormwater management technologies with their apparent characteristics of durability, adaptability to the environment, and sustainability. These technologies are the underpinning of modern achievements in sanitary engineering and wastewater management practices. It is the best proof that “the past is the key for the future”. Evolution of Sanitation and Wastewater Technologies through the Centuries is a textbook for undergraduate and graduate courses of Water Resources, Civil Engineering, Hydraulics, Ancient History, Archaeology, Environmental Management and is also a valuable resource for all researchers in the these fields.

Book Description
Small communities violate federal requirements for safe drinking water as much as three times more often than cities. Yet these communities often cannot afford to improve their water service. Safe Water From Every Tap reviews the risks of violating drinking water standards and discusses options for improving water service in small communities. Included are detailed reviews of a wide range of technologies appropriate for treating drinking water in small communities. The book also presents a variety of institutional options for improving the management efficiency and financial stability of water systems.

Book Description
THEY FLEW THROUGH THE AIR WITH GREATEST OF EASE Richard Halliburton can be counted on to lead his readers into strange places, into hilarious difficulties, into new appreciations of history and romance—and never to qualify his outrageous philosophy of reckless living with a single sober moral. The Flying Carpet is his latest, his most modern book—in which he takes us around the world by airplane. Timbuctoo, because it was far away and mysterious, was his first destination. From there, the author and his pilot-companion, Moye Stephens, follow a “royal road to romance” through the sky, dropping down on Fez, Morocco and the French Foreign Legion, The Holy Land, Galilee, Baghdad in mysterious Arabia, Persia, and India; flying over the world’s highest mountain, Mt. Everest, investigating Singapore, speeding to Borneo to visit the white Ranee whose husband rules half a million head hunters, and ending in Manila, making airplane records, enjoying unprecedented thrilling experiences, flying into remote places where airplanes had never been heard of before. These enviable adventures are told gaily and dramatically. Their footloose spirit, as free as the air through which the Flying Carpet sailed, will prove fatal to the contentment of those readers who have not yet achieved the realization of their own travel dreams.
