Available in PDF, EPUB and Kindle. Book excerpt: "Sanitation Safety Planning (SSP) is a step-by-step risk based approach to assist in the implementation of the 2006 WHO Guidelines for Safe Use of Wastewater, Excreta and Greywater in Agriculture and Aquaculture. The approach can be applied to all sanitary systems to ensure the system is managed to meet health objectives. SSP assists users to: systematically identify and manage health risk along the sanitation chain; guide investment based on actual risks, to promote health benefits and minimize adverse health impacts; provide assurance to authorities and the public on the safety of sanitation-related products and services. The SSP manual is targeted at a variety of users at different levels including; health authorities and regulators, local authorities, wastewater utility managers, sanitation enterprises and farmers, community based organizations, farmers associations and NGOs. SSP brings together actors from different sectors to identify health risks in the sanitation system and agree on improvements and regular monitoring and underscores the leadership role of the health sector."--Publisher's description.

Download or read book Feasibility of Onsite Residential Graywater Recycling Using a Semi batch Vertical Flow Wetland for Non potable Water Reuse written by Zita Lai Ting Yu and published by . This book was released on 2015 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water sustainability has become a critical issue in various regions around the world given rapid population rise and the impact of climate change on water resources. In this regard, onsite treatment and reuse of graywater (defined as wastewater is not originated from toilets or urinals), for non-potable applications, can be an important element of the approach to water sustainability. Treatment of graywater prior to reuse is essential in order to enable effective product water reuse and storage without creating nuisance, as well as comply with local regulatory requirements. In order to encourage adoption of graywater treatment, low-cost graywater treatment systems suitable for onsite residential deployment must be made available. The goal of the present research was to develop a low-cost, compact graywater treatment system using a semi-batch vertical flow wetland (SB-VFW) approach for residential graywater reuse for recycling. In order to assess the treatment performance and to elucidate the treatment mechanism and the removal kinetics, a SB-VFW system was developed and evaluated in a 13-month field study in a single-family home in Los Angeles. The SB-VFW consisted of a coconut coir dust layer (soil) and a cross flow media layer (CFM) was demonstrated to be effective for treatment of bathroom and laundry graywater. The treatment system was able to attain California Title 22 water reclamation requirements in ~3 hours for a 300-liter batch. The soil was found to be important for the removal of organics, turbidity, and suspended solids; while the use of CFM media enhanced aeration in the SB-VFW system. Organics removal in the SB-VFW was evaluated using a first-order kinetic model and found that graywater with lower organic removal rate constants stimulated more biomass growth and could lead to excess biomass accumulation when treatment time was short. Economic feasibility of onsite graywater treatment and reuse using SB-VFW systems were evaluated and found that a less-than-two-year return-on-investment could be achievable. Besides water-savings, energy required for graywater treatment using the SB-VFW approach was lower than the energy needed for potable water importation and centralized wastewater treatment. The present research demonstrated that onsite residential graywater treatment and reuse is both technically and economically feasible.

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.

Download or read book Decentralised Sanitation and Reuse written by Piet Lens and published by IWA Publishing. This book was released on 2001-03-01 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adopting a multi-disciplinary approach, Decentralised Sanitation and Reuse places public sanitation in a global context and provides a definitive discussion of current state-of-the-art sanitation technologies. It shows how these technologies can be implemented to integrate domestic waste and wastewater treatment in order to maximize resource recycling in domestic practice. Decentralised Sanitation and Reuse presents technical solutions for on-site collection and transport of concentrated waste streams, and focuses on the compromise between reliability and minimal water wastage. A whole range of available sustainable technologies, both low and high-tech, to treat concentrated (black water) and diluted (grey water) streams are addressed in detail from the fundamental scientific and engineering points of view. Sociological, economic and, particularly, environmental and public health aspects are essential issues within this book. The necessity of new infrastructure implementation and the resulting challenges for a good number of economic branches are illustrated with examples from architecture and town planning. Decentralised Sanitation and Reuse will be an invaluable resource for a wide academic and professional readership active in the fields of environmental protection and public sanitation.

Download or read book Water Reuse written by Chris Binnie and published by IWA Publishing. This book was released on 2008-05-14 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Reuse: An International Survey of current practice, issues and needs examines water reuse practices around the world from different perspectives. The objective is to show how differently wastewater reuse is conceived and practised around the world as well as to present the varied needs and possibilities for reusing wastewater. In the first section water reuse practices around the world are described for regions having common water availability, reuse needs and social aspects. The second section refers to the “stakeholders” point of view. Each reuse purpose demands different water quality, not only to protect health and the environment but also to fulfil the requirements of the specific reuse. Reuses considered are agricultural, urban agriculture as a special case of the former, municipal and industrial. Alongside these uses, the indirect reuse for human consumption through aquifer recharge is also discussed. The third section deals with emerging and controversial topics. Ethical and economical dilemmas in the field are presented as a subject not frequently addressed in this field. The role of governments in respect of public policy in reuse is discussed as well as the different international criteria and standards for reusing wastewater. The importance of public acceptance and the way to properly handle it is also considered. The fourth section of the book presents contrasting case studies; typical situations in the developed world (Japan and Germany) are compared to those in developing countries (Pakistan and Brazil) for agricultural and industrial reuse. Indirect planned reuse for human consumption (Germany) is compared with an unplanned one (Mexico). The Windhoek, Namibia case study is presented to emphasize why if the direct reuse of wastewater for human consumption has been performed with success for more than 35 years it is still the only example of this type around the world. To illustrate the difficulties of having a common framework for regulating water reuse in several countries, the Mediterranean situation is described. Other case studies presented refer to the reuse situation in Israel, Spain, Cameroon, Nepal and Vietnam, these latter countries being located in water rich areas. This book will be an invaluable information source for all those concerned with water reuse including water utility managers, wastewater policy makers and water resources planners as well as researchers and students in environmental engineering, water resources planning and sanitary engineering.
