Based on the work of the WASHCost project run by the IRC International Water and Sanitation Centre (IRC), this book provides an evaluation of the water, sanitation and hygiene (WASH) sectors in the context of developing countries and is the first systematic study of applying the life-cycle cost approach to assessing allocations. It presents unit cost estimates of the WASH sector across geographic locations and technologies, including rural and peri-urban areas, and these are compared with service levels. It analyses detailed data from more than 5000 households across nine agro-climatic zones in Andhra Pradesh State in India. Key issues assessed include poverty analysis of service levels, cost drivers and factors at the village and household level, and governance aspects such as transparency, accountability and value for money in relation to unit costs and service levels. This is the most comprehensive study of the WASH sector in India and elsewhere that utilises the life-cycle cost approach, along with GIS, econometric modelling and qualitative research methods. Not only does it contribute to research and methodology in this area, but the analysis also provides valuable insights for planners, policy makers and bi-lateral donors. The authors show how the methodology can also be applied in other developing country contexts.

The investments needed to deliver sustainable water and sanitation services are huge, yet most systems are underfunded. This book provides practical tools for investment and financial planning related to water.

Emerging Membrane Technology for Sustainable Water Treatment provides the latest information on the impending crisis posed by water stress and poor sanitation, a timely issue that is one of the greatest human challenges of the 21st century. The book also discusses the use of membrane technology, a serious contender that can be used to confront the crisis on a global scale, along with its specific uses as a solution to this escalating problem. - Provides a unique source on membrane technology and its application for water treatment - Focuses on technologies designed for the treatment of seawater and brackish water - Highlights the most economically and environmentally friendly membrane technologies - Lists various technologies and emphasizes their link to renewable energy, energy efficiency, nanotechnology, reuse, and recycle

This publication offers short descriptions of best practices and reviews of technology regarding water, sanitation and hygiene projects. The document is intended to provide guidance to field workers and non-technical program managers and decision makers. Topics include ecological sanitation, WASH needs assessments, rainwater collection, borehole drilling equipment and irrigation for home gardens.

Despite remarkable improvement in water supply and sanitation services, Estonia faces finance and investment challenges to keep up with social expectations and environmental health regulations. With downward demographic trends expected to affect water utilities revenues and the projected phasing out of EU water funding, which was essential in the rapid improvement of service provision over the last two decades, substantial efficiency gains are required to transition towards sustainable water service provision.

This report presents the discussions and conclusions of the OECD workshop on sustainable water consumption. It examines progress made on a range of key water policy issues and examines some of the more innovative attempts to put into practice a wider vision of integration.

Since the 1960s, it has been known that poor water and sanitation causes diarrhea, which consequently compromises child growth and leads to undernutrition. Ample evidence shows that poor water and sanitation causes diarrhea, but there is a growing body of knowledge discussing the magnitude of the impact of diarrhea on undernutrition. A recent hypothesis by Humphrey (2009), for example, states that the predominant impact of contaminated water and poor sanitation on undernutrition is via tropical/environmental enteropathy (triggered by exposure to fecal matter) rather than mediated by diarrhea. This new hypothesis has generated much debate, especially in the South Asia region, on the contribution of water and sanitation to the South Asian Nutrition Enigma. The region is characterized by unusually high rates of child undernutrition relative to its income level, as well as a slow reduction in undernutrition. Practitioners have struggled to decipher the reasons behind this 'anomaly.' This report provides a systematic review of the evidence to date, both published and grey literature, on the relationship between water and sanitation and nutrition. We also survey the potential impact of improved water, sanitation, and hygiene (WASH) on undernutrition. This is the first report that undertakes a thorough review and discussion of WASH and nutrition in Bangladesh. The report is meant to serve two purposes. First, it synthesizes the results/evidence evolving on the pathway of WASH and undernutrition for use by practitioners working in the nutrition and water and sanitation sectors to stimulate technical discussions and effective collaboration among stakeholders. Second, this report serves as an advocacy tool, primarily for policy makers, to assist them in formulating a multisectoral approach to tackling the undernutrition problem.

Bridging academic discussion and real-world case studies, this book considers the challenge, posed by SDG6, of balancing the provision of the basic human right of access to water whilst not eroding our capacity to live sustainably in a rapidly changing world.

The importance of small towns is gaining increased recognition as a result of two developments. The first development concerns the possible role of small towns in migration flows and urbanization. Development of small towns, in the form of improved basic services and other amenities, has been promoted in order to abate the impact of urbanization on large urban centres and to alleviate service provision pressures in major urban centers, whilst stimulating rural economies and eventually prompting social transformations. The second development concerns the targets set by the SDGs in 2015. SDG6 requires countries to ensure universal and equitable water services by 2030. This inclusive target requires that the water services needs of small towns are considered in the expansion of sustainable and equitable water services. This book aims to contribute to the study of water services in small towns by critically examining different approaches and experiences of water supply in small towns. It brings together empirical testimonies of how the implementation of reductionist models and the perseverance of certain principles underlying these models in the water sector have yielded suboptimal results. Much remains to be done before achieving universal service coverage in small towns is likely. In order to do that, we should start speaking of small towns as a category on their own and continue the work in elaborating further what these are and how they work. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.
