Substantially reducing the number of human beings who lack access to clean water and safe sanitation is one of the key Millennium Development Goals. This book argues and demonstrates that this can only be achieved by a better integration of the technical and social science approaches in the search for improved organization and delivery of these essential services. It presents a historical analysis of the development of water and sanitation services in both developed and developing countries, which provides valuable lessons for overcoming the obstacles facing the universalization of these...

Groundwater Hydrology of Water Resource Series - Water is an essential environmental resource and one that needs to be properly managed. As the world places more emphasis on sustainable water supplies, the demand for expertise in hydrology and water resources continues to increase. This series is intended for professional engineers, who seek a firm foundation in hydrology and an ability to apply this knowledge to solve problems in water resource management. Future books in the series are: Groudwater Hydrology of Springs (2009), Groudwater Hydrology of River Basins (2009), Groudwater...

No one has recorded when well digging started, but surely humans imitated elephants in digging holes in the sand to access cooler water that didn t make the children sick. Eventually, humankind began to redesign, maintain, and repair the wells they constructed, but when wells became "commodities" in the twentieth century, this maintenance ethic was fogotten. Recapturing that ethic, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation is a guide to keeping well systems operating at peak capacity. The book focuses on how to prevent and forestall problems,...

Based on the 'soft path' approach to the energy sector, a transition is now under way to a soft path for water. This approach starts by ensuring that ecosystem needs for water are satisfied and then undertakes a radical approach to reducing human uses of water by economic and social incentives, including open decision-making, water markets and equitable pricing, and the application of super-efficient technology, all applied in ways that avoid jeopardizing quality of life. The soft path for water is therefore a management strategy that frees up water by curbing water waste.

In past decades, urban water management practices focused on optimizing the design and operation of water distribution networks, wastewater collection systems, and water and wastewater treatment plants. However, municipalities are now faced with aging urban water infrastructures whose operation must be improved and expanded to maintain current high standards of living as well as new challenges such as climate change, systems sustainability and water quality issues. Integrating the latest developments in urban water hydrology and management, Urban Water Engineering and...

A growing proportion of the world s population is dependent on Seawater Desalination as a source of fresh water for both potable and civil use. One of the main drawbacks of conventional desalination technologies is the substantial energy requirement, which is facing cost increases in the global energy market. "Seawater Desalination" presents an overview of conventional and non-conventional technologies, with a particular focus on the coupling of renewable energies with desalination processes.

The first section of this book presents, in a technical...
