Download or read book User-centered guidance for engineering and design of decentralized sanitation technologies written by Laura Morrison. This book was released on 2018-06-27. Available in PDF, EPUB and Kindle. Book excerpt: Technological innovations in sanitation are poised to address the great need for sanitation improvements in low-income countries. Worldwide, more than 2.4 billion people lack access to improved sanitation facilities. Innovative waste treatment and sanitation technologies aim to incorporate user-centered findings into technology engineering and design. Without a focus on users, even the most innovative technology solutions can encounter significant barriers to adoption. Drawing on a household survey conducted in urban slum communities of Ahmedabad, India, this research brief identifies toilet and sanitation preferences, amenities, and attributes that might promote adoption of improved sanitation technologies among potential user populations. This work uses supplemental insights gained from focus groups and findings from the literature. Based on our research, we offer specific guidance for engineering and design of sanitation products and technologies.

Book Synopsis Regenerative Sanitation by : Thammarat Koottatep

Download or read book Regenerative Sanitation written by Thammarat Koottatep. This book was released on 2019-02-15. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes Regenerative Sanitation as the next era of sanitation management and attempts to provide a foundation for the study of sanitation on the premise that sanitation is a complex and dynamic system that comprises of social-ecological, technological and resource systems. The preconception is that sanitation will deliver maximal benefits to society only when there exists a cyclical integration of the three subsystems to enable appropriate linkages between ‘technological design’ and the ‘delivery platform’ so as to achieve optimal and sustained sani-solutions. It also calls for the rethinking of sanitation to change the narrative towards more progressive trajectories such as resource recovery and reuse rather than just amelioration. It explores the contributions to food security, livelihood support, urban regeneration, rural development and even local economies. A new paradigm, theory and ten principles for ensuring practical and effective sanitation solutions and management is presented. In addition is a unique conceptual framework applicable to both developed and developing countries, and to all stages, processes and cycles of delivering sanitation solutions that could critically evaluate, analyse and provide credible, adequate and appropriate sanitation solutions. All of which culminates in a strategic and practical application platform called ‘Sanitation 4.0’ that advocates for total rejuvenation and comprehensive overhaul with eight key strategic considerations for the implementation. Regenerative Sanitation: A New Paradigm For Sanitation 4.0 is inter and trans- disciplinary and encourages collaboration between engineers, scientists, technologists, social scientists and others to provide effective and practical user-centred solutions. It includes relevant case studies, examples, exercise and future research recommendations. It is written as both a textbook for researchers and students as well as a practitioners’ guide for policymakers and professionals.

Book Synopsis Decentralized Sanitation Systems for Densely Populated Regions by : Andrew Lee Tsang

Download or read book Decentralized Sanitation Systems for Densely Populated Regions written by Andrew Lee Tsang. This book was released on 2021. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 7.5 billion people live presently on earth, and 2.3 billion lack access to basic sanitation facilities such as toilets or latrines. The International Water Association estimates that 80% of all wastewater gets discharged into waterways. Untreated wastewater affects the community as easily as water flows. Toilets with septic tanks and latrines are the primary repositories for human waste today. However, the essential subsequent task of disposing that fecal sludge or septage is rarely done in a safe manner. A lack of safe, official dumping sites means this sludge and septage is discretely disposed of in water ways, pits, or drains, which affect the local health and aesthetics. The main question posed in this thesis is "What are cost effective ways to building sanitation infrastructure in developing countries?" This thesis presents a design of a decentralized system conceptualized, prototyped, and analyzed using tools of systems engineering and systems analysis. The development of a lab-scale processor is presented in this thesis. The lab scale system processes 3.5kg of 20% sludge per hour. Using a trade space analysis, the system is compared to other methods of fecal sludge processing; a decentralized method can obtain similar health results for 15-25% of the cost per person served. A systems complexity analysis was done to compare options, and then the economic implementation was analyzed using Monte Carlo simulation. The findings suggest a decentralized model is very cost effective, but not cost effective enough to be a standalone business outside of government purchase
