J. (2004). Sustainable Environmental Protection Using Modified Pit-Latrines. Ph.D Thesis, Wageningen University, The Netherlands. Pit-latrines are on-site excreta disposal facilities widely used as anaerobic accumulation system for stabilizing human wastes like excreta, both in rural and urban settlements of developing countries. Flooding of pit-latrines is often a common phenomenon, especially in situations of high water table (HWT) conditions and during the rainy season, causing a health jeopardy to residents. The pits are not water-tight, the (ground)water can freely flow in and out of the pit, especially in HWT areas. -
HEALTH ASPECTS of DRY SANITATION with WASTE REUSE Anne Peasey
HEALTH ASPECTS OF DRY SANITATION WITH WASTE REUSE Anne Peasey Task No. 324 WELL STUDIES IN WATER AND ENVIRONMENTAL HEALTH Health Aspects of Dry Sanitation with Waste Reuse Anne Peasey WELL Water and Environmental Health at London and Loughborough Health Aspects of Dry Sanitation with Waste Reuse ii London School of Hygiene and Tropical Medicine Keppel Street London WC1E 7HT © LSHTM/WEDC Peasey, A. (2000) Health Aspects of Dry Sanitation with Waste Reuse WELL Designed and Produced at LSHTM Health Aspects of Dry Sanitation with Waste Reuse EXECUTIVE SUMMARY BACKGROUND Dry sanitation is defined in this report as the on-site disposal of human urine and faeces without the use of water as a carrier. This definition includes many of the most popular options for low- cost sanitation including pit latrines, Ventilated Improved Pits, SanPlats, etc. There has always been an interest in the reuse of human waste as a fertiliser, and there has been much recent work on the development of composting and other processes to permit human waste reuse. This report examines the practice of dry sanitation with reuse in Mexico, with a particular focus on health issues and the lessons to be learned from case studies and experience. DRY SANITATION WITH REUSE There are two distinct technical approaches to dry sanitation with reuse; · Dehydration. Urine and faeces are managed separately. The deposited faecal matter may be dried by the addition of lime, ash, or earth, and the contents are simply isolated from human contact for a specified period of time to reduce the presence of pathogens. · Decomposition (composting) In this process, bacteria, worms, or other organisms are used to break organic matter down to produce compost. -
Composting Toilets: a Review* of Their Use in Public Venues in the U.S

As one person has remarked, flush toilets are the accepted social standard. The idea of collecting human excrement in a basement composting bin does not exactly square with the modern paradigm of gracious living. There is, however, more to the story. In what follows, we describe six composting toilet installations of varying types, currently installed for public use in locations in the United States, including three in California. We consider only those for institutional, industrial, municipal and commercial venues, i.e., those for which maintenance can be assured. We do not consider composting toilet installations for residential use. In our descriptions, we include comments by administrators, architects and users. As we shall see, every one of these six installations is positively viewed. We also include a section on frequently asked questions, including discussions of costs and possible legal barriers. Manufacturers: Clivus Multrum is the leader A comprehensive list of manufacturers of composting toilets is available as a pdf that may be downloaded from http://www.susana.org/en/resources/library/details/876. -

In an emergency setting, the choice of ecosan options is very often driven by factors other than the re-use of all or part of the by-products. Ecosan toilets are very often better suited to rocky ground or areas with high water tables, making them more resistant to cyclic flooding for instance. -
The Cultural and Environmental Unsoundness of the Chinese Public Squatting-Type Toilet: a Case Study Toward a Sustainable Excreta Treatment System
Environ. Eng. Res. 2014 March,19(0), 0-0 Research Paper http://dx.doi.org/10.4491/eer.2014.19.0.0 pISSN 1226-1025 eISSN 2005-968X In Press, Uncorrected Proof The Cultural and Environmental Unsoundness of the Chinese Public Squatting-type Toilet: A Case Study toward a Sustainable Excreta Treatment System Jin-Soo Chang Molecular Biogeochemistry Laboratory, Biological & Genetic Resources Institute (BGRI), Hannam University (Jeonming), 505 Inno-Biz Park, 1646 Yuseong-daero, Yeseong-gu, Daejeon 305-811, Republic of Korea Abstract The inconvenient truth of sustainable public squat toilet culture varies among nationalities. According to the adequate environmental management in Yanbian Korean Autonomous Prefecture (YKAP), northern China, this culture may be comfortable to the people of China, yet uncomfortable to the non-Chinese. We conducted a series of field surveys and individual interviews (Chinese n = 1000 and non-Chinese (foreign visitors) n = 100) on several aspects of the public squat toilet: structural properties, waste disposal methods, important factors, and overall satisfaction level. The significant factors in response to the public squat toilets were cleanliness, odor, toilet paper, temperature, soap, other facilities, and presence of cubicles. These factors should be the policy priorities of local government. In addition, 66.2% of Chinese and 91% of foreign visitors desired type E toilets (two full-height partition walls per cubicle, with a door). The results illustrate the nature of a sustainable and aesthetic approach to the culturally and environmentally sound management of various types of public squat toilet in YKAP. The government needs to focus on the future-oriented and excreta treatment management of the sustainable toilet culture for the residents of, and visitors to, YKAP. -

2 the Robo-Toilet Revolution the Actress and the Gorilla
George, Rose, 2014, The Big Necessity: The Unmentionable World of Human Waste and Why It Matters (pp. 39-64). Henry Holt and Co.. Kindle Edition. 2 THE ROBO-TOILET REVOLUTION THE ACTRESS AND THE GORILLA The flush toilet is a curious object. It is the default method of excreta disposal in most of the industrialized, technologically advanced world. It was invented either five hundred or two thousand years ago, depending on opinion. Yet in its essential workings, this everyday banal object hasn’t changed much since Sir John Harington, godson of Queen Elizabeth I, thought his godmother might like something that flushed away her excreta, and devised the Ajax, a play on the Elizabethan word jakes, meaning privy. The greatest improvements to date were made in England in the later years of the eighteenth century and the early years of the next by the trio of Alexander Cumming (who invented a valve mechanism), Joseph Bramah (a Yorkshireman who improved on Cumming’s valve and made the best lavatories to be had for the next century), and Thomas Crapper (another Yorkshireman who did not invent the toilet but improved its parts). In engineering terms, the best invention was the siphonic flush, which pulls the water out of the bowl and into the pipe. For the user, the S-bend was the godsend, because the water that rested in the bend created a seal that prevented odor from emerging from the pipe. At the height of Victorian invention, when toilets were their most ornate and decorated with the prettiest pottery, patents for siphonic flushes, for example, were being requested at the rate of two dozen or so a year. -
Adventures in an Outhouse
Adventures in an Outhouse During the summer of 1940 Shirley Scott's family was living in a tent in Butterfield Canyon to be closer to where her dad was working in the mine. While they were living in the canyon the only bathroom that they had was an outhouse. One day Shirley's brother Max, who was five years old, was in the outhouse. He had his favorite toy car with him and was using the toilet seat as a racetrack. He was driving his car around the seat when he accidentally dropped it down the hole. Max really liked his car so he stuck his arm down the hole and tried to reach it but it was too far down. He couldn’t get it on his own so he asked Shirley to help him. Shirley was seven years old and was more than willing to do what she could to help her little brother. The solution that they came up with was to have Shirley hold onto Max’s legs and lower him down the hole so he could grab the car. What could be simpler? The plan was working out fine until Shirley lost her grip on Max’s legs and dropped him headfirst into the nasty stuff that you find at the bottom of an outhouse. The sides of the pit were dirt so Max couldn’t get a grip on anything and he started sinking. He hollered for Shirley to help him but she couldn’t bring herself to put her hand down the hole to rescue him. -

Sustainable Sanitation – a Case Study in Yasmine and Awda Informal Settlements (Lebanon)
Master's Thesis 2019 30 ECTS Faculty of Environmental Sciences and Natural Resource Management Sustainable sanitation – A case study in Yasmine and Awda informal settlements (Lebanon) Elisa Winger Eggen Master of Science in Water and Environmental Technology (M-VM) PREFACE This MSc thesis is my final work of the Master of Science in Water- and Environmental Technology at Norwegian University of Life Sciences (NMBU). The research is based on fieldwork undertaken from the 27th of January until the 3rd of March 2019 in Bekaa Valley, Bar Elias, Lebanon, aimed to find sustainable sanitation solutions in two refugee camps. The study has been carried out in close collaboration with Norwegian Church Aid (NCA), International Orthodox Christian Charities (IOCC) and Multiconsult. My motivation for this thesis was based on a desire to choose a research topic that could be meaningful for others, and my interest in water and sanitation in developing countries. I sincerely hope this will contribute to improvements and implementation of a holistic sanitation system which will benefit the people in the studied camps. Ås, May 14th, 2019 Elisa Winger Eggen I II ACKNOWLEDGEMENTS Working on this thesis has been exciting, challenging and educational. There is a lot of effort invested in the final version of the thesis, and the learning process to this point has been invaluable. Many have contributed to this work, whom I will like to thank; First and foremost, my deepest gratitude goes to my main supervisor, Professor Petter D. Jenssen, for his enormous inspiration, engagement, valuable feedback and support along the way. I would also like to thank Tor Valla (Multiconsult), Ioannis Georgiadis (NCA) and Manfred Arlt (NCA) for introducing me to this project in Lebanese refugee camps, where my education would be relevant and applied in practice. -
1.5 Design of Composting Toilet for Practical Application in Burkina Faso
Design of composting toilet for practical application in Burkina Faso Kenta Yabui*, Ken Ushijima, Ryusei Ito, Naoyuki Funamizu Department of Environmental Engineering, Graduate school of Engineering, Hokkaido University, Kita-13, Nishi-8, Kita-ku, Sapporo 060-8628, Japan [email protected] 011-706-6272 Abstract Resource recycling sanitation system, which utilize composting toilet, is one of the promising concept to improve the sanitary conditions in developing countries. In this sanitation system, toilet has to have two functions; sanitary equipment and fertilizer generator. As sanitary equipment, toilet has to provide clean, safe, comfortable environment for daily defecation. As fertilizer generator, toilet has to convert urine and feces into safe and good quality of fertilizer. The composting toile should be designed in order to perform both two functions in high quality, with low cost. In this research, design requirements for toilet as sanitary equipment and fertilizer generator are abstracted basing on field survey to 6 families from 3 villages in rural area of Burkina Faso. According to abstracted requirements, one design of composting toilet was proposed for rural area of Burkina Faso. The feces degradation performance was same level as commercial composting toilet and required torque for mixing was smaller than commercial screw type composting toilet. Key words: user oriented design, resource recycling sanitation system, composting toilet 1. Introduction Currently, in Burkina Faso, people living in rural area can access to improved toilet are 6%. In Millennium developing Goals (MDGs), the target is the number of people do not have improved sanitary facilities reduces by half by 2015. In that area, the progress of installation of sanitary facilities to achieve MDGs is too low, while more than half of the people still have open defecation culture or unimproved toilets, especially poor people.
