The main purpose of this book is to assist the reader in choosing the best method for providing clean and safe water in a developing country. The sites needing clean water can be diverse, e.g. an individual household, an entire village, a group of villages, a school, a clinic, an orphanage, etc. The focus of this book is to provide the reader with a basic understanding of how to bring clean water supplies to these entities. The optimal approaches will depend on both the Point of Use (POU), which may be large or small, and the state of the water (quantity, turbidity, type and concentration of pathogens/bacteria/viruses present) at the water source. Point of Use (POU) is the location where the water is to be consumed.The majority of those impacted by unsafe water live in isolated rural areas of the developing world. Cost, sustainability, cultural differences and acceptance by those who will use the water are all important factors in providing clean drinking water to these people.

Drinking water availability and safety is a major challenge faced globally and is highly pronounced in developing countries worldwide. Lack of safe potable water across the globe can be attributed to industrial pollution, climate change and other human activities that result in a spectrum of chemical, physical and biological pollutants entering a water body. Although efforts to solve this problem are well underway worldwide, challenges still exist. This book shines a light on drinking water treatment methods and scale of operation specifically for the developing countries. Covering both conventional and emerging treatment technologies, the authors discuss the removal of chemical, physical and biological pollutants from drinking water, with a focus on developing countries. Conservation by rainwater harvesting, wastewater reuse, and selection criteria of feasible methods are considered in the context of issues relevant to Africa, Asia, Latin America and the Caribbean. With case studies connecting theory to real world matters, showcasing efficiencies and drawbacks, this book is ideal for graduate and postgraduate level course use in engineering departments or for self-study and research.

As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.

The new 2030 Agenda for Sustainable Development includes water, sanitation, and hygiene (WASH) at its core. A dedicated Sustainable Development Goal (SDG 6) declares a commitment to "ensure availability and sustainable management of water and sanitation for all." Monitoring progress toward this goal will be challenging: direct measures of water and sanitation service quality and use are either expensive or elusive. However, reliance on household surveys poses limitations and likely overstated progress during the Millennium Development Goal period. In Innovations in WASH Impact Measures: Water and Sanitation Measurement Technologies and Practices to Inform the Sustainable Development Goals, we review the landscape of proven and emerging technologies, methods, and approaches that can support and improve on the WASH indicators proposed for SDG target 6.1, "by 2030, achieve universal and equitable access to safe and affordable drinking water for all," and target 6.2, "by 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations." Although some of these technologies and methods are readily available, other promising approaches require further field evaluation and cost reductions. Emergent technologies, methods, and data-sharing platforms are increasingly aligned with program impact monitoring. Improved monitoring of water and sanitation interventions may allow more cost-effective and measurable results. In many cases, technologies and methods allow more complete and impartial data in time to allow program improvements. Of the myriad monitoring and evaluation methods, each has its own advantages and limitations. Surveys, ethnographies, and direct observation give context to more continuous and objective electronic sensor data. Overall, combined methodologies can provide a more comprehensive and instructive depiction of WASH usage and help the international development community measure our progress toward reaching the SDG WASH goals.

There are 17 comprehensive and detailed Sustainable Development Goals, which are all interlinked. Although access to water, sanitation, and hygiene is a human right, billions of people in developing countries are still faced with daily challenges accessing even the most basic of services, specifically the poor and vulnerable in communities. Hygiene is an important aspect for women/girls to access the economic, educational, and social opportunities they deserve. Proper hygiene removes disease as a barrier for equality, economic growth, and more. The role of hygiene in water, sanitation, and infections must be addressed from both scientific and social perspectives. This book provides the reader with an analysis of hygiene behaviors and practices and provides evidence-based examples in a number of developing countries.

The little-known story of the systems that bring us our drinking water, how they were developed, the problems they are facing, and how they will be reinvented in the near future

From the founders of nonprofits Water.org & WaterEquity Gary White and Matt Damon, the incredible true story of two unlikely allies on a mission to end the global water crisis for good On any given morning, you might wake up and shower with water, make your coffee with water, flush your toilet with water—and think nothing of it. But around the world, more than three-quarters of a billion people can’t do any of that—because they have no clean water source near their homes. And 1.7 billion don’t have access to a toilet. This crisis affects a third of the people on the planet. It keeps kids out of school and women out of work. It traps people in extreme poverty. It spreads disease. It’s also solvable. That conviction is what brought together movie actor Matt Damon and water expert and engineer Gary White. They spent years getting the answer wrong, then halfway right, then almost right. Over time, they and their organization, Water.org, have found an approach that works. Working with partners across East Africa, Latin America, South Asia, and Southeast Asia, they’ve helped over 40 million people access water and/or sanitation. In The Worth of Water, Gary and Matt take us along on the journey—telling stories as they uncover insights, try out new ideas, and travel between the communities they serve and the halls of power where decisions get made. With humor and humility, they illuminate the challenges of launching a brand-new model with extremely high stakes: better health and greater prosperity for people allover the world. The Worth of Water invites us to become a part of this effort—to match hope with resources, to empower families and communities, and to end the global water crisis for good. All the authors’ proceeds from the sale of this book will be donated to Water.org.
