Book Description
It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Book Description
Over the past few years on-site sanitation has been widely promoted as a solution which can be quickly implemented to address sanitation issues, and it is gaining traction. As such, treatment of the contents emptied from on-site containments has become a pressing issue. While dedicated treatment facilities for this purpose have been advocated, co-treating these wastes in sewage treatment facilities is a promising option, which many countries have implemented or are exploring. This option maximises the utilisation of city infrastructure. In cases where the existing sewage treatment facilities are underutilised, co-treatment presents a ready solution for managing fecal sludge and septage. In spite of co-treatment being a well-known practice in many countries, it remains clouded in uncertainty, especially regarding the technical advisability, and potential risks of co-treating fecal sludge or septage in sewage treatment plants. Planners and decision-makers are often very apprehensive in considering co-treatment. As a result, the opportunity to better utilise available infrastructure for co-treatment of sludge is often being missed. Meanwhile, there are also many cases where co-treatment has been tried, either successfully or otherwise, but it has not been possible to draw conclusions from these, to guide the way forward. This guide book explores some of the basic principles behind sewage treatment, and how it may be impacted by co-treatment of wastes from on-site containments, to try to throw some light on how co-treatment could be considered, in an incremental manner, recognising risks and mitigating them. It is intended to facilitate a better understanding among planners, engineers, decision makers and technical practitioners and to help them evaluate and consider the option of co-treatment.

Book Description
"Many middle- and low-income countries are experiencing rapid urbanization, which creates a need for services, including sanitation. While some areas in some towns and cities are sewered, most people, especially the urban poor, continue to use various forms of on-site sanitation. These require periodic emptying and the material removed from them must be treated before reuse or discharge to the environment. Faecal Sludge and Septage Treatment confronts the urgent need to treat increasing volumes of faecal sludge and septage in the rapidly expanding towns and cities of the global south. It discusses the urban contexts that influence treatment requirements and overall septage treatment processes. It examines the options and design approaches at each stage of treatment, from reception, through preliminary treatment, solids -- liquid separation, anaerobic and aerobic treatment of the separated liquid and solid fractions to systems to render treated products suitable for reuse in either agriculture or as a fuel. Faecal Sludge and Septage Treatment provides straightforward guidance on the options for faecal sludge treatment and the choices between those options. All concepts and approaches are clearly explained so as to make Faecal Sludge and Septage Treatment accessible to a non-specialist readership"--

Book Description
This book presents a methodology for preparing scheduled desludging schemes in cities. Opening with a description of its definition and principles, this book outlines step by step the preparation of a scheduled desludging scheme. Coverage of the book includes a feasibility assessment of a city to implement a scheduled desludging program, getting everybody on the same principles, making the general concept, setting targets, designing the operational scheme, building capacity of the service provider, preparing the fleets, and preparing promotion activities for the desludging program. Several fecal sludge desludging options and the implication of each option are discussed in the book, including their financial implications. The book also presents methods to calculate the operational cost and how the cost can be used as the basis to determine the desludging tariff. This book was written based on the experience of USAID - IUWASH (Indonesia Urban Water and Sanitation and Health) program in assisting several Indonesian cities in preparing their mandatory desludging program. Some of Indonesia's specific narratives and terms used in the original book have been adapted for the benefit of readers from other countries.

Book Description
On-site sanitation systems, such as septic tanks and pit latrines, are the predominant feature across rural and urban areas in most developing countries. However, their management is one of the most neglected sanitation challenges. While under the Millennium Development Goals (MDGs), the set-up of toilet systems received the most attention, business models for the sanitation service chain, including pit desludging, sludge transport, treatment and disposal or resource recovery, are only emerging. Based on the analysis of over 40 fecal sludge management (FSM) cases from Asia, Africa and Latin America, this report shows opportunities as well as bottlenecks that FSM is facing from an institutional and entrepreneurial perspective.

Book Description
Onsite sanitation systems (OSS) have burgeoned in urban India as sewer infrastructure has not been able to catch up with the rapid urbanization and growth. India’s aspirational flagship program on sanitation and hygiene -- the Swachh Bharat Mission (Clean India Campaign) – has abetted the construction of toilets with the aims to increase access to, and the use of, toilets to eliminate open defecation. However, management of fecal sludge (FS) generated by the OSS is critical for sustainable sanitation. FS needs to be safely contained, emptied, transported, and disposed of or reused after adequate treatment. In un-sewered cities of India, the services of emptying and transporting FS are mainly provided by privately-run cleaning trucks. Lack of adequate fecal sludge treatment plants (FSTPs) compel the trucks to either dispose of the FS without any treatment or facilitate its reuse in agriculture. In this dissertation, we trace the activities that kick in when a pit fills up. Based on a thick description of septic tank cleaning trucks in Bangalore and Dharwad (Karnataka, India), we find that the physical, social and financial mechanisms through which the back-end services are organized are virtually invisible in national fecal sludge management policies (Chapter 2). We show that it is rational, under the current conditions, for trucking operations to externalize the costs of urban pollution and social (i.e. caste) inequality that are produced and reproduced when they “manage” fecal waste. We draw on the literatures on invisibility and the social role of disgust to explain the seen-and-unseen nature of these trucks. “Seeing” sludge management as it is practiced today is essential for understanding how the sanitary city is being produced and for the success of any ongoing or future sanitation reform policies. Though mechanization of sanitation services is increasing, the societal perception of sanitation workers has not changed much. Chapter 3 elicits the lived experiences of sanitation workers from the opposite ends of the spectrum – manual scavenging and mechanical emptying. The chapter uncovers the daily lives and the human side of sanitation workers, to emphasize the humanity of sanitation workers in India. Considerable amount of untreated FS is reused in agriculture in the peri-urban areas of Dharwad and Bangalore. Chapter 4 unpacks the ecosystem of FS reuse by tracing why and how FS reaches a farm, and why and how it is used (or not) once it gets there. In this chapter, we estimate farm owners’ preferences for treated fecal sludge-based fertilizer, gauge workers’ willingness to work with FS and with FSF and identify worker practices of potential health risks. We find truck operators are facilitating and even promoting FS reuse in agriculture for lack of ease of disposal. Farm owners show a strong inclination towards reusing FS, even if it is untreated. Such a reuse potentially harms the health of farm workers We also find that both the farm owners and workers have positive preferences towards certain characteristics of treated FS. We conclude with a short chapter that summarizes the key findings and opens up discussion for future research that can potentially build upon or contribute to our findings.
