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. -

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. -

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. -
Investigation Into Methods of Pit Latrine Emptying April 2009
WRC PROJECT 1745 Management of sludge accumulation in VIP latrines Investigation into Methods of Pit Latrine Emptying April 2009 by Mark O’Riordan Mark O’Riordan Investigation of Methods of Pit Latrine Emptying Page - i Executive Summary Improving sanitation is now increasingly being recognized as a key factor in ending poverty; providing basic sanitation has been included in the Millennium Development Goals (MDGs) under target 10 of halving the proportion of people without access to adequate basic sanitation by 2015. In an attempt to reach this MDG target many developing countries have embarked on the construction of pit latrines and improved sanitation in people’s homes. An emerging challenge that is resulting from this work is what to do when the latrines are full. If they are to be emptied how should the waste be extracted, where should the waste go and what should be done to it and with it? The approaches to meeting this question are the focus of this report. The report aims to summarise all information currently available to PID resulting from; • General research • Durban’s pit latrine emptying programme • Work with the Vacutug on loan from UN Habitat • A visit to UN Habitat in Nairobi • Site visit to Vacutug facilitating charity Maji na Ufanisi working in Kibera, Nairobi • Design and development work on the ‘Gobbler’ The main part this report is a fairly high level introduction to the issue of faecal sludge management. Where details and information have been readily available the report goes into further depth. A large section of this report focuses on assessment of the United Nations Vacutug project in an attempt to build guidance for the development of a successful latrine exhausting system. -

EECCA NWO Activity Report 2013‐2016 Introduction The Eastern Europe, Caucasus and Central Asia Network of Water Management Organizations (EECCA NWO) was established to promote exchange of ideas, accumulated experience, and information on different aspects of water management activity. The Network’s activity is facilitated by the Scientific‐Information Center of ICWC (as the Network’s Secretariat) and AO “Vodstroy” and supported by the Government of the Russian Federation and the UN Economic Commission for Europe. The Network closely collaborates with the International Network of Basin Organizations. Membership in this Network is voluntary, based on professional unity and mutual understanding, and excludes any financial fees. The Network’s activity is focused on: Organization of annual (as far as possible) conferences gathering all members of the Network Publication of scientific paper collections Maintenance of a web‐site, which serves as the Network’s “knowledge hub” accumulating and shedding light on know‐how, scientific developments and intellectual products of the Network members. The web‐site contains reports and resolutions of the Network Conferences, information about its members’ events, and e‐versions of scientific paper collections. Preparation, publication and dissemination of the Russian version of «INBO Newsletter» Currently, the membership of the Network comprises 84 organizations from 12 countries, including: Russia ‐ 19, Ukraine ‐ 6, Kazakhstan ‐ 12, Tajikistan ‐ 4, Turkmenistan ‐ 1, Uzbekistan ‐ 17, Azerbaijan ‐ 2, -
