Book Description
Richard Carter weaves together the myriad of factors that need to come together to make rural water supply truly available to everyone. He concludes that ultimately, systemic change to the global web of injustice that divides this world into rich and poor may be the only way to address the underlying problem.

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
Rural Water Systems for Multiple Uses and Livelihood Security covers the technological, institutional, and policy choices for building rural water supply systems that are sustainable from physical, economic, and ecological points-of-view in developing countries. While there is abundant theoretical discourse on designing village water supply schemes as multiple use systems, there is too little understanding of the type of water needs in rural households, how they vary across socio-economic and climatic settings, the extent to which these needs are met by the existing single use water supply schemes, and what mechanisms exist to take care of unmet demands. The case studies presented in the book from different agro ecological regions quantify these benefits under different agro ecological settings, also examining the economic and environmental trade-offs in maximizing benefits. This book demonstrates how various physical and socio-economic processes alter the hydrology of tanks in rural settings, thereby affecting their performance, also including quantitative criteria that can be used to select tanks suitable for rehabilitation. Covers interdisciplinary topics deftly interwoven in the rural context of varying geo-climatic and socioeconomic situations of people in developing areas Presents methodologies for quantifying the multiple water use benefits from wetlands and case studies from different agro ecologies using these methodologies to help frame appropriate policies Provides analysis of the climatic and socioeconomic factors responsible for changes in hydrology of multiple use wetlands in order to help target multiple use water bodies for rehabilitation Includes implementable models for converting single use water supply systems into multiple use systems

Book Description
The Waterbackpack PAUL -Portable Aqua Unit for Life Saving- is a water treatment unit based on the Ultra-Low Pressure Ultrafiltration (ULP-UF) technology and is since 2010 successfully applied as a fast response to get safe water during natural disasters or emergencies in more than 2 000 cases worldwide. In addition, PAUL has demonstrated that the ULP-UF technology can be used in permanent decentralised drinking-water supply for remote and rural areas, as it is easy to handle and does require neither chemicals nor energy consumption nor spare parts on a regular basis. Hence, the ULP-UF is an appropriate solution in the process of reaching the Sustainable Development Goals (SDGs), ensure by 2030 access to safe drinking water worldwide. However, during long-term uses and under certain water characteristics, the ULP-UF faces some operational and maintenance challenges. The biofouling adhered to the membrane surface may lead to severe flux reduction. In addition, some re-growth of bacteria may take place on the permeate side because of the presence of high content of natural organic matter (NOM) in the raw water, especially Biopolymer and Humic Acids. Therefore, the aim of this study was to integrate some appropriate treatment steps before the ULP-UF technology, so that a reduction of attachment of NOM and biofilm to the membrane could be achieved and thus an increase of permeate flux and a reduction of potential regrowth of bacteria on permeate water could be accomplished.
