Guide to Sanitation Natural Disasters GUIDE TO SANITATION IN NATURAL DISASTERS M. ASSAR WORLD HEALTH ORGANIZATION GENEVA 1971 WORLD HEALTH ORGANIZATION The World Health Organization (WHO) is one of the specialized agencies in relationship with the United Nations. Through this organiza­ tion, which came into being in 1948, the public health and medical professions of more than 130 countries exchange their knowledge and experience and collaborate in an effort to achieve the highest possible level of health throughout the world. WHO is concerned primarily with problems that individual countries or territories cannot solve with their own resources-for example, the eradication or control of malaria, schistosomiasis, smallpox, and other communicable diseases, as well as some cardiovascular diseases and cancer. Progress towards better health throughout the world also demands international cooperation in many other activities: for example, setting up international standards for biological substances, for pesticides and for pesticide spraying equip­ ment; compiling an international pharmacopoeia; drawing up and administering the International Health Regulations; revising the inter­ national lists of diseases and causes of death; assembling and dissemi­ nating epidemiological information; recommending non-proprietary names for drugs; and promoting the exchange of scientific knowledge. In many parts of the world, there is need for improvement in maternal and child health, nutrition, nursing, mental health, dental health, social and occupational health, environmental health, public health administra­ tion, professional education and training, and health education of the public. Thus a large share of the Organization's resources is devoted to giving assistance and advice in these fields and to making available-­ often through publications-the latest information on these subjects. Since 1958 an extensive international programme of collaborative research and research coordination has added substantially to knowledge in many fields of medicine and public health. This programme is con­ stantly developing and its many facets are reflected in WHO publications. GUIDE TO SANITATION IN NATURAL DISASTERS GUIDE TO SANITATION IN NATURAL DISASTERS M. ASSAR, M.S.S.E.

Ugarte, Professor, Faculty of Medicine, University of Chile, and Adviser in Health Planning, Ministry of Public Health, Santiago, Chile -7- PREFACE For some time the World Health Organization has been concerned about the lack of practical information and recommendations concerning environ­ mental sanitation in emergencies and natural disasters. Hardly any systematic studies of the question have been made, and there are few countries where standing instructions have been issued on environmental sanitation under disaster conditions or where emergency sanitation supplies and equipment have been prepared and stockpiled. When disasters occur, there is an urgent need for technical information on emergency procedures for water supply, disposal of excreta and other wastes, food and milk sanitation, disinfection and disinfestation, and the rapid control of flies, mosquitos, rats, and other insect and rodent pests. In the early stages of a disaster, much confusion and delay can be avoided if the staff in charge of sanitation relief know exactly what to do to remedy the most serious damage promptly and efficiently. It is clear that these needs cannot be met without careful planning and long preparation by the health authorities. Relief workers need to be given simple and practical instructio'1S on how to perform their tasks under the abnormal and hazardous conditions created by a catastrophe. As each disaster has its own characteristics, and as each country has varying means and resources at its disposal, it is impossible to recommend specific measures that are applicable to all emergencies everywhere. Never­ theless, certain elements of emergency sanitation are common to most natural disasters. This Guide provides basic information on the principles of emergency sanitation and contains detailed instructions for carrying out certain tasks. It is intended primarily to assist health authorities and relief agencies in developing their relief plans and in preparing themselves to cope efficiently with the sanitation problems caused by a disaster. The author has long and outstanding experience in emergency sanitation practice; as Director-General of the Division of Sanitary Engineering in the Ministry of Health of Iran he was responsible for all environmental health relief to victims of floods and earthquakes. A first draft of this Guide was circulated to a number of experts in different parts of the world for their comments and suggestions, which have been taken into account in preparing the final text. A list of these reviewers will be found on page 7. The League of Red Cross Societies-the world federation of national Red Cross Societies-has collaborated in this project since its inception. -9- The League's wide experience in the provision and co-ordination of emergency aid for victims of disasters, its assistance in obtaining documents issued by national Red Cross Societies, and its wise advice and sound recommendations have been extremely helpful in the preparation of this Guide. The World Health Organization expresses its sincere gratitude to the League oIRed Cross Societies, to the reviewers, and particularly to the author, Mr M. Assar. -10 - 1. INTRODUCTION Despite the tremendous achievements of modern technology mankind remains virtually helpless in the face of such natural disasters as floods, hurricanes, volcanic eruptions, and earthquakes, which attack populated centres and

  • A Review of the Evidence Base for WASH Interventions in Emergency Responses / Relief Operations
    A Review of the Evidence Base for WASH interventions in Emergency Responses / Relief Operations A Review of the Evidence Base for WASH interventions in Emergency Responses Discussion document Submitted by Jonathan Parkinson January 2009 January 2009 Page 1 of 56 A Review of the Evidence Base for WASH interventions in Emergency Responses / Relief Operations Executive summary Inadequate sanitation, inadequate water supplies and poor hygiene are critical determinants for survival of victims of natural disasters and conflict situations, especially in the initial stages of a disaster. The most significant are diarrheal diseases and infectious diseases transmitted by the faeco-oral route nd a combination of these factors means that people affected by disasters are also generally much more susceptible to illness and death from disease The traditional response by relief agencies in emergency situations has been to install water supply points and latrines. But experiences have clearly demonstrated the limitations of this approach. More recently hygiene promotion has taken increasingly greater predominance as an integral part of relief agency operations. However, these experiences are diverse and this has led to questions about which type of hygiene promotion activity is most effective and how. Consequently, in the course of the extensive inter-agency consultation, it has emerged that much of the existing evidence base which underpins decision-making for WASH interventions in relief operations is extrapolated from the development sector. It is unclear to the extent to which it is appropriate and relevant in emergency contexts. The primary aim of this assignment was therefore to explore whether it is considered appropriate to apply the existing evidence base for WASH interventions to support emergency operations as it stands and, if not, to consider what activities may be required to improve the evidence base.

  • Emergency Sanitation – Technical Options
    Emergency sanitation – technical options World Health Organization The immediate provision of clean water supplies and sanitation facilities in refugee camps is essential to the health, well-being and, in some cases, even the survival of the refugees. Sanitation is usually allocated a much lower priority than clean water, but it is just as important in the control of many of the most common diseases found in refugee camps. Sanitation is the efficient disposal of excreta, urine, refuse, and sullage. As indiscriminate defecation is normally the initial health hazard in refugee camps, this note outlines ways in which it can be controlled temporarily while Figure 1. Plan of a defecation field long-term solutions are devised. Immediate measures Preventing defecation in certain areas The technical options for emergency excreta disposal When a large group of people are excreting are limited and simple. If they are to work, however, indiscriminately, it is necessary, first of all, to protect they must be managed well and be understood and the food-chain and water supplies from contamination. supported by the community. This means preventing people defecating on: The immediate tasks at a new camp include: the banks of rivers, streams, or ponds which may be used as a water source. If water is to be obtaining the services of a good translator and abstracted from shallow wells, then it is important consulting with all interested parties including to ensure that these wells are situated upstream representatives of the refugees, aid agencies, and of the defecation areas; or government officials; agricultural land planted with crops, particularly if surveying the site to gather information on the crops are soon to be handled or harvested for existing sanitation facilities (if any), the site human consumption.

  • Emergency Sanitation the Loss of Clean Running Water Or Loss of A
    Emergency Sanitation The loss of clean running water or loss of a functional sewer system after a disaster can dramatically increase the chances of diarrheal diseases and outbreaks. Just one gram of human feces may have 100 parasite eggs, 1,000 parasite cysts, 1 million bacteria, and as many as 10 million viruses! With this risk all around us, it underscores the importance of staying clean and disposing of human and other waste properly after a disaster. Pathogens that may present a risk after a disaster include Escherichia Coli (E. Coli), Leptospirosis, hepatitis A, norovirus, and in some situations Vibrio cholerae and Salmonella enterica. Exposure to disease causing pathogens may occur as a result of contaminated water, sharing of water containers and cooking equipment, or the loss of basic sanitation such as the ability to wash hands thoroughly. Even brushing your teeth with water that is not safe for consumption can result in exposure to pathogens. Avoiding exposure to these pathogens starts with a careful assessment of water quality following a disaster. Because municipal water lines run parallel to sewer lines, even a small break in both lines can result in cross-contamination. Follow guidance from local officials on use of municipal water following a disaster (e.g., shutting off water to house, treating water before use, or flushing system). Once a reliable, clean water source has been established, emphasis should be placed on two key priorities: a) providing a mechanism for personal hygiene and handwashing and b) managing human waste. Personal Hygiene and Handwashing Any questionable tap water used for drinking and personal hygiene (hand-washing, brushing teeth) must be boiled or otherwise disinfected.

  • WASH Cluster Sanitation Technical Working Group Guidelines for Household Level Sanitation Updated October 2019
    WASH Cluster Sanitation Technical Working Group Guidelines for Household Level Sanitation Updated October 2019 Context The Government of Mozambique aim is to eliminate the practice of open defecation across the country by 2025 and universal access to basic sanitation by 2030. It has been done through the mass mobilization of communities on behavioral change messages, certifying open defecation free communities, and strengthening sanitation markets. Prior to the cyclones Kenneth and Idai, the rate of open defecation in the rural areas has been high across the affected provinces Sofala (67%), Manica (45%) and Zambezia (72%). This means that even households not directly impacted by the cyclone or floods, have a high probability of practicing open defecation. The two cyclones that affected Mozambique, Idai and Kenneth, have had a profound impact on the population and the access to sanitation infrastructures. Two main affected groups can be recognized; the people resettled in new rural areas (“resettlement sites”), and the generally affected population by cyclonic winds and/or floods. The first group can be categorized as the most vulnerable, followed by the generally affected area that remained in their habitual place of residence. Sanitation interventions for relocation centers and first phase emergency support in resettlement sites focused on the construction of temporary emergency communal latrines. The guidelines for this sanitation support is included in the Mozambique WASH Cluster Emergency Sanitation Guidelines1. Their construction was often undertaken by humanitarian agencies, where materials, and sometimes labor, were fully subsidized. After the acute emergency needs for construction of latrines for communal latrines for 1:5 households the WASH Cluster will support the construction of household latrines in resettlement sites and affected communities using a dome slab modality to improve sanitation access and to encourage improved hygiene behaviors.
