Book Synopsis Greywater Use in the Middle East by : Stephen McIlwaine
Download or read book Greywater Use in the Middle East written by Stephen McIlwaine and published by IDRC. This book was released on 2010 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: In water-scarce areas of the Middle East, greywater (household wastewater excluding toilet waste) is commonly used by poor communities to irrigate home gardens. This both supplements the water available to the household and improves food security. This book draws together material presented at a conference in Jordan in 2007, and examines the technical approaches to treating and using greywater for irrigation, including its associated risks to health and the environment. It discusses many of the non-technical issues that influence effectiveness and sustainability of greywater use. It also takes a hard look at economic issues, arguing that more clarity and consistency from policymakers is essential if low-income, water-stressed communities are to make better and safer use of their existing water supplies. The book concludes by offering suggestions for where donor efforts and research could best be focused in the near future.Greywater use in the Middle East is important reading for researchers, donors, implementing agencies, and policymakers, in the fields of water supply, water reuse, livelihoods and agriculture.

Book Synopsis Municipal Wastewater Management in Developing Countries by : Zaini Ujang
Download or read book Municipal Wastewater Management in Developing Countries written by Zaini Ujang and published by IWA Publishing. This book was released on 2006-04-30 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Municipal Wastewater Management in Developing Countries discusses various approaches to municipal wastewater management in order to protect both public health and the environment, with the major focus being on waterborne diseases. Developing countries can be divided into two main categories, i.e. countries in transition with higher growth rates where industrialisation and urbanisation are taking place rapidly, and countries with slower growth rates. It is important, therefore, that approaches should be tailor-made and site-specific. In general, the major trends of water pollution control have significantly contributed to the development of ?conventional sanitation? approaches in terms of legal and financial frameworks, as well as technological enhancement. Despite advances in the science, engineering and legal frameworks, 95 per cent of the wastewater in the world is released into the environment without treatment. Only five per cent of global wastewater is properly treated using the ?standard? sanitation facilities, mainly in developed countries. As a result, the majority of the world?s population is still exposed to waterborne diseases, and the quality of water resources has been rapidly degraded, particularly in poor developing countries. The challenge now is to provide the world?s population, especially the poor, with adequate water and sanitation facilities. Despite billions of dollars of investment spent every year, billions of poor people are still suffering and dying because of poor sanitation. At the beginning of this century, about 1.1 billion people lived without access to clean water (compared to about the same number in 1990), 2.4 billion without appropriate sanitation (compared to 2.3 billion in 1990) and four billion without sound wastewater disposal. The future scenario, that water resources will be further depleted by a growing world population, will be coupled with environmental degradation due to poor pollution control, particularly in most of the developing countries. In order to address the issue of water and wastewater management in developing countries it is necessary to take into consideration the segments of the society itself, particularly the types of housing areas. The segments will indicate the level of socio-economic, mentality and knowledge, which is important for any planned changes in their life style and social engineering. It is also important to segregate the funding framework of any proposed projects. High-income urban communities, for instance, are generally willing to pay for sewerage services and higher water supply tariffs, therefore a designated system can be accordingly provided. Over the past 10 years, serious criticism has been given to the ?conventional sanitation? approach, consequently many definitions, concepts and characteristics have been proposed on ?sustainable sanitation?. Sustainable sanitation is a relevant concept in order to achieve the Millennium Development Goals by 2015 of providing water supply and adequate sanitation for developing countries. Sustainable sanitation is flexible in approach any community ? poor or rich, urban or rural, water-rich or water-poor country ? and requires lower investment costs compared to conventional sanitation approaches. It is also important to note that the framework of sustainable sanitation is much easier to adopt in developing countries where water supply and sanitation infrastructures are still in the developing stages. In some developing countries, no public facilities are available therefore it is an ideal condition to start a new infrastructure with a new framework. This comprehensive reference, prepared by leading international authorities, will provide an invaluable reference for all those concerned with the management of sanitation services in developing countries worldwide.
Book Synopsis Domestic Wastewater Treatment in Developing Countries by : Duncan Mara
Download or read book Domestic Wastewater Treatment in Developing Countries written by Duncan Mara and published by Routledge. This book was released on 2013-06-17 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Affordable and effective domestic wastewater treatment is a critical issue in public health and disease prevention around the world, particularly so in developing countries which often lack the financial and technical resources necessary for proper treatment facilities. This practical guide provides state-of-the-art coverage of methods for domestic wastewater treatment and provides a foundation to the practical design of wastewater treatment and re-use systems. The emphasis is on low-cost, low-energy, low-maintenance, high-performance 'natural' systems that contribute to environmental sustainability by producing effluents that can be safely and profitably used in agriculture for crop irrigation and/or in aquaculture, for fish and aquatic vegetable pond fertilization. Modern design methodologies, with worked design examples, are described for waste stabilization ponds, wastewater storage and treatment reservoirs; constructed wetlands, upflow anaerobic sludge blanket reactors, biofilters, aerated lagoons and oxidation ditches. This book is essential reading for engineers, academics and upper-level and graduate students in engineering, wastewater management and public health, and others interested in sustainable and cost-effective technologies for reducing wastewater-related diseases and environmental damage.

Book Synopsis Alternative Water Supply Systems by : Fayyaz Ali Memon
Download or read book Alternative Water Supply Systems written by Fayyaz Ali Memon and published by IWA Publishing. This book was released on 2014-10-15 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to climate change related uncertainties and anticipated population growth, different parts of the developing and the developed world (particularly urban areas) are experiencing water shortages or flooding and security of fit-for-purpose supplies is becoming a major issue. The emphasis on decentralized alternative water supply systems has increased considerably. Most of the information on such systems is either scattered or focuses on large scale reuse with little consideration given to decentralized small to medium scale systems. Alternative Water Supply Systems brings together recent research into the available and innovative options and additionally shares experiences from a wide range of contexts from both developed and developing countries. Alternative Water Supply Systems covers technical, social, financial and institutional aspects associated with decentralized alternative water supply systems. These include systems for greywater recycling, rainwater harvesting, recovery of water through condensation and sewer mining. A number of case studies from the UK, the USA, Australia and the developing world are presented to discuss associated environmental and health implications. The book provides insights into a range of aspects associated with alternative water supply systems and an evidence base (through case studies) on potential water savings and trade-offs. The information organized in the book is aimed at facilitating wider uptake of context specific alternatives at a decentralized scale mainly in urban areas. This book is a key reference for postgraduate level students and researchers interested in environmental engineering, water resources management, urban planning and resource efficiency, water demand management, building service engineering and sustainable architecture. It provides practical insights for water professionals such as systems designers, operators, and decision makers responsible for planning and delivering sustainable water management in urban areas through the implementation of decentralized water recycling.

Book Synopsis Wastewater Treatment and Reuse for Metropolitan Regions and Small Cities in Developing Countries by : Müfit Bahadir
Download or read book Wastewater Treatment and Reuse for Metropolitan Regions and Small Cities in Developing Countries written by Müfit Bahadir and published by Cuvillier Verlag. This book was released on 2017-01-27 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Water Management is essential for the social, economic, and environmental growth of developing countries. Many of those had very high population growth rates in the last century, resulted in fast urbanization and strengthened by heavy migration from rural areas to the cities either of big or small size. Water supply of good quality and adequate quantity, especially in countries with semi-arid regions, and appropriate sewerage systems and treatment of wastewaters impaired severe constraints for the population. Nevertheless, many alternatives for wastewater treatment were developed with the participation of universities and research institutions as well as by practitioners. Substantial efforts have been directed towards the search of good alternatives for domestic sewage treatment in metropolitan regions and small cities in developing countries in order to comply with their particular economic and environmental conditions. The use of conventional treatment technologies as well as advanced alternatives for treatment and post-treatment of wastewater, issues of plant scales in centralized and decentralized systems, and possible reuse of the effluents were aimed to present on this workshop and to discuss theoretical and practical aspects. The main objectives of the workshop were (i) to share experiences, knowledge, and research between different partners; (ii) to discuss major problems and challenges in the field of wastewater treatment and reuse in Metropolitan Regions and Small Cities in Developing Countries; (iii) to present suitable treatment technologies for domestic wastewater for the removal of recalcitrant substances and micro-pollutants from domestic sewage and industrial effluents; and (iv) likeliness of reuse of treated wastewater in urban areas, in the industry, and in agriculture. Individual topics dealt with were (v) alternatives for domestic sewage treatment in metropolitan regions and small cities; (vi) anaerobic processes for the treatment of domestic sewage and industrial wastewaters; (vii) stabilization ponds; (viii) aerobic granular sludge; (ix) post-treatment processes; (x) centralized and decentralized systems; and (xi) water reuse.
