Available in PDF, EPUB and Kindle. Book excerpt: As water demand has increased globally and resources have become more limited because of physical scarcity, over-exploitation and pollution, it has been necessary to develop more options for water supplies. These options include the production at large scale of high-quality reused water from municipal sources for potable uses. Their economic, social and environmental benefits have been many as they have addressed supply scarcity, efficient resource use and environmental and public health considerations. This book includes discussions on potable water reuse history; emerging contaminants and public health; public-private partnerships in the water reuse sector; regulatory frameworks for reused water in the United States and Europe; experiences in Australia, China in general and Beijing in particular, Singapore and Windhoek; narratives and public acceptance and perceptions of alternative water sources. The main constraints on implementation of water reuse projects in different parts of the world seem to have been lack of full public support due to perceived health hazards and environmental impacts. A main handicap has been that governments and water utilities have been slow to understand public concerns and perceptions. After several backlashes, public information, communication and awareness campaigns, broader participation and educational programmes have become integral parts of development policy and decision-making frameworks.

Available in PDF, EPUB and Kindle. Book excerpt: Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

Available in PDF, EPUB and Kindle. Book excerpt: Milestones in Water Reuse: The Best Success Stories illustrates the benefits of water reuse in integrated water resources management and its role for water cycle management, climate change adaptation and water in the cities of the future. Selected case studies are used to illustrate the different types of water reuse, i.e. agricultural irrigation, golf course and landscape irrigation, urban and industrial uses, environmental enhancement, as well as indirect and direct potable reuse. The various aspects related to water reuse are covered, including treatment technologies, water quality, economics, public acceptance, benefits, keys for success and main constraints. These international case studies highlight the best practices for the implementation of water reuse and provide the perspective for the integration of water recycling projects in the future, both for megacities and rural areas. Milestones in Water Reuse: The Best Success Stories demonstrates that planned water reuse is a cost competitive and energy-saving option to increase water availability and reliability. This book provides policy makers and regulators with a good understanding of water reuse and helps them to consider recycled water as safe and how it can be used. It is intended to be read by all people in the water sector and shows how water reuse is safe, economically viable, environmentally friendly and can provide high social benefits.

Download or read book Principles for Optimizing the Scale of Direct Potable Water Reuse written by Tianjiao Guo and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The US National Research Council recently recommended direct potable water reuse (DPR), or potable water reuse without environmental buffer, for consideration to address rising US water demand. In addition, conveyance of wastewater and water to and from centralized treatment plants currently consumes on average four times the energy of treatment in the US. Moreover, scaling of DPR systems involves tradeoffs beyond those of treatment facility economy-of-scale versus cost and energy of conveyance. In particular, additional factors favoring distributed DPR include minimization of energy for upgradient distribution of treated water, and retention of wastewater thermal energy. Therefore, a network modeling study addressing the optimal scale of DPR plants, considering variability in population density and topography, is presented in this dissertation. First, information on the cost of unit treatment processes potentially useful for DPR versus system capacity is reviewed, converted to constant 2012 US dollars, and synthesized. A logarithmic variant of the Williams Law cost function is proposed as applicable over orders of magnitude of system capacity, for the subject processes: activated sludge, membrane bioreactor, coagulation/flocculation, reverse osmosis, ultrafiltration, peroxone and granular activated carbon. Results are then demonstrated versus 10 DPR case studies. A generalized model of the cost of DPR water as a function of treatment plant scale, assuming futuristic, optimized conveyance networks, is then proposed for purposes of developing design principles. Fractal landscapes representing flat, hilly, and mountainous topographies were simulated, with urban, suburban, and rural housing distributions placed by modified preferential growth algorithm. Treatment plants were allocated by agglomerative hierarchical clustering, networked to buildings by minimum spanning tree. Simulation results indicate total DPR capital and operation & maintenance (O&M) costs, assuming new urban facilities with 20-year design life capable of mineralizing chemical oxygen demand to below detection limits, is competitive with current water/wastewater service costs at scales of ca. one plant per 10,000 residences. Costs for rural systems are high and dominated at most scales by the cost of capital for pipeline installation, while urban/suburban system cost is driven by a balance between pipeline installation and treatment equipment capital. The optimal scale of mineralizing DPR systems is projected to range widely in rural areas, and to range to service populations at least as small as 100 homes in suburban areas and 1000 residences in urban areas. Therefore, distributed DPR systems are recommended for consideration for municipal water and wastewater system capacity expansion projects, particularly in new construction zones. Finally, the proposed model is applied and demonstrated to evaluate the feasibility and optimal scale of DPR plants versus current plans for treatment capacity expansion in Miami-Dade County, Florida. Local data on the distribution of population and housing structures, and topography, were input, to evaluate four scenarios for the expansion service area: (a) proposed new wastewater treatment plant (WWTP) and assumed new water treatment plant treating County-projected flow; (b) central DPR treating flow expected under generalized conditions; (c) central DPR treating County-projected flow; (d) optimal distributed DPR treating expected generalized flow; and (e) new central water and wastewater systems treating expected generalized flow. Results suggest that DPR systems which mineralize organics so as to essentially eliminate discharge of endocrine-disrupting compounds to the environment may represent a practical alternative in many applications. Total cost was minimized at a scale of 46 plants for the service population of 671,823(4,810 per plant). Though DPR capital cost is projected at approximately twice that of the current plan, the total unit cost of $13.00/1000 gallons when added to O&M costs is approximately 51% higher than might be estimated for the current plan, and is less than reported for several major US cities and Florida municipalities. Overall, the model presented in this work confirms DPR as a potential water management alternative to address increasing water demand in the future, and presents an optimization approach that may be useful in planning studies. General design principals regarding the scale of DPR systems include the use of 100-10,000-home DPR systems in urban/suburban areas, and consideration of systems that return nutrients to agricultural sectors in rural areas.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In recent times, the coalescence of different pressure has put a major strain on water supply globally. The level of water abstraction is reaching its natural limits, and this calls for a dramatic shift in water utilization concepts. This publication addresses the economic and financial issues and the methodology and procedures involved in the analysis of water recycling projects as part of a comprehensive water planning process. The issue is dealt within the wider context of water resources and covers human health, water quality, acceptability, institutional constraints, and other factors, all of which have economic implications and affect the feasibility of reuse schemes. The recycling of urban wastewater is a key link in Integrated Water Resource Management that can fulfill several different, but interrelated objectives. These are expressed as win-win propositions, delivering simultaneous benefits to farmers, cities and natural environmental systems, part of solutions to the urgent global problems of food, clean water, the safe disposal of waters and the protection of the vital aquatic ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: A 2023 Choice Reviews Outstanding Academic Title Move past the “yuck factor” by learning the benefits and science behind recycling wastewater to beat climate change. In recent years, humans have begun to turn the age-old taboo against mixing sewage and drinking water on its head by using advanced treated wastewater to supplement a city’s drinking water supply. This increasingly widespread practice, known as potable reuse, qualifies as nothing less than a drinking water revolution. Water reuse offers a renewable, locally managed, and drought resistant water supply. The Water Recycling Revolution tracks the story of this development, examines the pros and cons, and explores its future potential. In this book, William M. Alley and Rosemarie Alley answer our most pressing questions: How do you get people to overcome the visceral reaction known as the “Yuck Factor” and not only drink, but appreciate, recycled water? What about all those pharmaceuticals and personal care products that people casually flush down the drain? Will diverting discharges from a wastewater treatment plant damage downstream users or ecosystems that previously depended on that water? And what are the implications for climate change? These questions are answered by delving into the history of major water recycling projects from California to Virginia, each with a unique story of what led them to develop potable reuse, as well as the challenges they had to overcome. Additional concerns addressed include pathogens, contaminants of emerging concern, achieving acceptable risk, onsite and decentralized reuse systems, and directpotable reuse. Recycling wastewater can make for a bright future in the fight against climate change, and this book is a valuable resource to convince readers.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the water shortages, population growth, and competing demands for water in California, the possibility of incorporating direct potable reuse technology in the state's water supply portfolio is being considered by various water resource providers. This paper focuses on public acceptance challenges that may be encountered. By evaluating best practices employed by six different potable water reuse case studies, recommendations for future direct potable reuse projects are developed. It is recommended that future project proponents plan early and conduct public opinion surveys regarding this type of technology, develop and implement public outreach and education plans that include best practices defined in the case study analysis, and develop outreach and education materials that meet the interests of various audiences. Specific practices that should be considered include: educating the public about where existing supply sources come from when describing the need for DPR technology, garnering support from health professionals and local politicians, targeting outreach efforts to groups of people that may be wary of this type of technology, and offering public tours of advanced water purification facilities.
