Privatization of Water Services in the United States

Privatization of Water Services in the United States PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 0309170761
Category : Science
Languages : en
Pages : 158

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.

Security of Water Supply Systems: from Source to Tap

Security of Water Supply Systems: from Source to Tap PDF Author: Jaroslav Pollert
Publisher: Springer Science & Business Media
ISBN: 9781402045622
Category : Business & Economics
Languages : en
Pages : 204

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.

Fair, Geyer, and Okun's, Water and Wastewater Engineering PDF Author: Nazih K. Shammas
Publisher: John Wiley and Sons
ISBN: 0470411929
Category : Technology & Engineering
Languages : en
Pages : 867

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.

Advanced Water Supply and Wastewater Treatment: A Road to Safer Society and Environment

Advanced Water Supply and Wastewater Treatment: A Road to Safer Society and Environment PDF Author: Petr Hlavinek
Publisher: Springer Science & Business Media
ISBN: 9400702795
Category : Technology & Engineering
Languages : en
Pages : 355

Book Description
Stable, safe, secure and readily available water supply is one of the key factors in ensuring a good level of the public health and a stable society. Scientific assessments show that about 80 % of diseases and one-third of the total death toll in the developing countries are caused by the low quality of the drinking water. Other countries are also suffering from water shortages and insufficient quality of the drinking water. Many rivers in Europe and in other parts of the world are significantly polluted by insufficiently treated or untreated wastewater discharge. This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Lviv, Ukraine, and addressed recent advances in water supply and wastewater treatment as a prerequisite for a safer society and environment. The contributions critically assess the existing knowledge on urban water management and provide an overview of the current water management issues, especially in the countries in transition in Central and Eastern Europe and in the Mediterranean Dialogue countries.

Best-practice Management of Water Supply and Sewerage

Publisher:
ISBN: 9780975223208
Category : Sewerage
Languages : en
Pages : 60

Book Description
"The guidelines encourage continuing improvement in performance and identify 6 criteria for best-practice management of water supply and sewerage. They also set out the outcomes local government Local Water Utilities (LWUs) need to achieve in order to be eligible for payment of a dividend from the surplus of their water supply or sewerage businesses."--Foreword.

Evolution of Sanitation and Wastewater Technologies through the Centuries

Evolution of Sanitation and Wastewater Technologies through the Centuries PDF Author: Andreas N. Angelakis
Publisher: IWA Publishing
ISBN: 1780404840
Category : Science
Languages : en
Pages : 558

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.
