The third edition of the WHO Guidelines for the Safe Use of Wastewater, Excreta and Greywater has been extensively updated to take account of new scientific evidence and contemporary approaches to risk management. The revised Guidelines reflect a strong focus on disease prevention and public health principles. This new edition responds to a growing demand from WHO Member States for guidance on the safe use of wastewater, excreta, and greywater in agriculture and aquaculture. Its target audience includes environmental and public health scientists, researchers, engineers, policy-makers and those responsible for developing standards and regulations. The Guidelines are presented in four separate volumes: Volume 1: Policy and regulatory aspects Volume 2:Wastewater use in agriculture Volume 3: Wastewater and excreta use in aquaculture Volume 4: Excreta and greywater use in agriculture. Volume 1 of the Guidelines presents policy issues and regulatory measures distilled from the technical detail found in volumes 2, 3, and 4. Those faced with the need to expedite the development of policies, procedures, and regulatory frameworks, at national and local government levels, will find the essential information in this volume. It also includes summaries of the other volumes in the series. Volume 2 of the Guidelines explains requirements to promote safe use concepts and practices including health-based targets and minimum procedures. It also covers a substantive revision of approaches to ensuring the microbial safety of wastewater used in agriculture. It introduces health impact assessment of new wastewater projects. Volume 3 of the Guidelines informs readers on the assessment of microbial hazards and toxic chemicals and the management of the associated risks when using wastewater and excreta in aquaculture. It explains requirements to promote safe use practices, including minimum procedures and specific health-based targets. It puts trade-offs between potential risks and nutritional benefits in a wider development context. Volume 4 of the Guidelines focuses exclusively on the safe use f excreta and greywater in agriculture. Recent trends in sanitation, including ecological sanitation, are driven by rapid urbanization. The momentum created by the Millennium Development Goals is resulting in dramatic changes in human waste handling and processing. New opportunities enable the use of human waste as a resource for pro-poor agricultural development, particularly in periurban areas. Best practice to minimize associated health risks is at the heart of this volume.

Volume 4 of the Guidelines for the safe use of wastewater, excreta and greywater provides information on the assessment and management of risks associated with microbial hazards. It explains requirements to promote the safe use of excreta and greywater in agriculture, including minimum procedures and specific health-based targets, and how those requirements are intended to be used. This volume also describes the approaches used in deriving the guidelines, including health-based targets, and includes a substantive revision of approaches to ensuring microbial safety

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

The effective integration of water and reclaimed wastewater still requires close examination of public health issues, infrastructure and facilities planning, wastewater treatment plant siting, treatment process reliability, economic and financial analyses, and water utility management. This book assembles, analyzes, and reviews the various aspects of wastewater reclamation, recycling, and reuse in most parts of the world. It considers the effective integration of water and reclaimed wastewater, public health issues, infrastructure and facilities planning, waste-water treatment plant siting, treatment process reliability, economic and financial analysis, and water utility management.

Water Health is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. These volumes discuss matters of great relevance to our world on desalination which is a critically important as clearly the only possible means of producing fresh water from the sea for many parts of the world. The two volumes present state-of-the art subject matter of various aspects of water health such as: Water And Health; Classification Of Water-Related Disease; Burden Of Disease: Current Situation And Trends; Transmission And Prevention Of Water-Related Diseases; Goals Of Water Treatment And Disinfection: Reduction In Morbidity And Mortality; Diseases Associated With Drinking Water Supplies That Meet Treatment And Indicator Specifications; New And Emerging Waterborne Infectious Diseases; Safe Drinking Water In The Twenty-First Century: Priorities For Public Health; Health Impact And Economic Costs Of Poor Water And Sanitation; Water Safety Plans For Water Technologies; Hygiene Promotion; Institutional Issues In The Delivery Of Water And Sanitation Services; Economics And Financing In The Water Sector; Monitoring Drinking Water Supplies; Zoonoses Acquired Through Drinking Water; Microbiological Water Quality Assessment (Catchment To Tap); Epidemiologic Studies Of Disinfectants And Disinfectant By-Products; Health Effects Of Chemical Contamination Of Drinking Water Supplies; Unconventional Sources Of Water Supply; Point-Of-Use Water Treatment For Home And Travel; Treatment And Safe Storage Of Water In Households Without Piped Supplies Of Treated Water; Quantifying Health Risks In Wastewater Irrigation Impacts Of Eutrophication On The Safety Of Drinking And Recreational Water; Groundwater And Public Health; Aquaculture And Mariculture; Recreation In Natural Water Resources; Dry Sanitation Technologies - Can They Be Sustainable?; Constraints To Improving Water And Sanitation Services; Human Health In Water Resources Development; Toxic Cyanobacteria; Multiple Uses Of Water And Human Health; Health Impact Assessment; Water Reclamation And Reuse; Role Of Water Reuse In Management Of Urban Water Resources; The Uses Of Recycled Water; Coming To Terms With Nature: Water Reuse New Paradigm Towards Integrated Water Resources Management; Helminth Ova Control In Wastewater And Sludge For Agricultural Reuse. These volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy and Decision Makers
