Oxfam Water Supply Scheme for Emergencies. This manual is part of a series of guides devised by the Oxfam Public Health Engineering Team to help provide a reliable water supply for populations affected by conflict or natural disaster. Wherever possible, water supplies in emergency conditions should ...be obtained from underground sources by exploitation of springs, tubewells, or dug wells. No filtration will then be needed. However, if sources are not available or cannot be developed, the use of surface water from streams, rivers, lakes or ponds becomes necessary. Usually these surface sources are polluted. The level of faecal contamination can be measured by use of the Oxfam/Delagua Water Test Kit (see Section C). Where a serious level of faecal pollution exists, it is essential firstly to try to reduce the cause of contamination, and secondly to treat the water to make it suitable for human consumption. The Filtration equipment provides a simple, long-term physical and biological treatment system that requires no chemicals (except small amounts of chlorine required during filter cleaning) and needs only simple regular maintenance

Examples of small-scale disinfection products for safe drinking water
WaterAid is an international NGO that provides assistance for safe water supply,
sanitation and hygiene practice in the poor communities in the world.
In this review, the editors will investigate the impact of eight WASH interventions in preventing (reducing the risk of) and controlling outbreaks in LMIC, with particular focus on three diseases of current concern to the response community – cholera, Ebola, and Hepatitis E. Additionally, we will ...explore economic outcomes related to WASH interventions within an outbreak

In order to maintain daily operations and patient care services, health care facilities need to develop an Emergency Water Supply Plan (EWSP) to prepare for, respond to, and recover from a total or partial interruption of the facilities’ normal water supply. Water supply interruption can be caused... by several types of events such as natural disaster, a failure of the community water system, construction damage or even an act of terrorism.
The planning guide provides a four step process for the development of an EWSP:
1. Assemble the appropriate EWSP Team and the necessary background documents for your facility;
2. Understand your water usage by performing a water use audit;
3. Analyze your emergency water supply alternatives; and
4. Develop and exercise your EWSP

Disinfection of drinking-water supplies has been one of the most significant public health advancements of the last century with respect to reducing waterborne disease.
Although chlorine has been used as the disinfectant of choice for public drinking-water supplies for the past century, a numbe...r of emerging or alternative compounds are used or are being considered for the disinfection of drinking-water.
This series reviews the state of the knowledge on the application, efficacy and toxicity of bromine, iodine and silver as drinking-water disinfectants.

A review of proactive risk assessment and risk management practices to ensure the safety of drinking-water
Based on information gathered from 118 countries representing every region of the globe, this report provides a picture of WSP uptake worldwide. It presents information on WSP implementati...on and the integration of WSPs into the policy environment. It also explores WSP benefits, challenges and future priorities.

The WHO/UNICEF JMP report, WASH in Health Care Facilities, is the first comprehensive global assessment of water, sanitation and hygiene (WASH) in health care facilities. It also finds that 1 in 5 health care facilities has no sanitation service*, impacting 1.5 billion people. The report further rev...eals that many health centres lack basic facilities for hand hygiene and safe segregation and disposal of health care waste.

This rapid review report has identified the wastewater treatment plant (WWTP) options used in emergency settings, with decentralised wastewater treatment systems (DEWATS) and mobile wastewater treatment units performing most effectively and with minimal costs. Examples are taken from refugee camps a...nd internally displaced people (IDP) settlements due to the Iraq war, the Israeli-Palestine conflict, and the civil wars in Syria and Sudan. WWTP options used in Finland, Haiti, Iraq, Jordan, Palestine, Sudan and Turkey are discussed. Lessons learned from China and suggestions for the Rohingya crisis are also included.

During fresh fruit and vegetables (FFV) production, water is used for a variety of purposes. Even the water was conventionally treated and disinfected, it may still potentially contain human pathogens, albeit at low concentrations. A risk assessment, appropriate to the national or local production c...ontext, should be conducted to assess the potential risks associated with a specific water source or supply in order to devise the appropriate risk mitigation strategies.
Since the 48th session of Codex Committee on Food Hygiene (CCFH) noted the importance of water safety and quality in food production and processing, FAO and WHO has undertaken the work on this subject. This report describes the output of the third in a series of meetings, which examined appropriate and fit-for-purpose microbiological criteria for water used with fresh fruit and vegetables. The advice herein will support decision making when applying the concept of fit-for-purpose water for use in the pre- and post-harvest production of fresh fruit and vegetables.

At its 48th session of Codex Committee on Food Hygiene (CCFH), the Committee noted the importance of water quality and safety in food production and processing. CCFH requested the Food and Agriculture Organization of the United Nations
(FAO) and the World Health Organization (WHO) to provide guidan...ce for those scenarios where the use of “clean water” (i.e. water that does not compromise the safety of the food in the context of its use) was indicated in Codex texts and on
where it is appropriate to use “clean water”. In particular, guidance was sought for the use of irrigation water and “clean” seawater and on the safe reuse of processing water.

Las Guías para la calidad del agua de consumo humano: pequeños sistemas de abastecimiento de agua se han elaborado para tratar las necesidades y oportunidades asociadas a los pequeños sistemas de abastecimiento, con el fin de facilitar la mejora progresiva hacia unos servicios seguros y sostenibl...es de agua de consumo humano para todas las personas. Estas Guías se basan en la recomendación principal de las Guías para la calidad del agua de consumo humano de la Organización Mundial de la Salud, y proporcionan orientación sobre la aplicación de esas recomendaciones a los pequeños sistemas de abastecimiento de agua en particular. El objetivo de estas Guías consiste en ayudar a los gobiernos y a los profesionales a mejorar la seguridad del agua de consumo humano suministrada a través de pequeños sistemas de abastecimiento.

Around the world, more than 2 billion people lack access to safely managed water, sanitation and hygiene services, with conflicts and climate change exacerbating the issue.
Unsafe and insufficient WASH facilities, especially in rural and remote areas, can lead to increased health complications fo...r older people, persons with disabilities and children. They also reinforce cycles of poverty, inequality and deprivation – particularly for women, children and marginalized groups, who are disproportionately impacted by a lack of equitable access to water and sanitation.
Launched on World Water Day, the guidelines address the knowledge gap on ways to practically implement inclusive approaches to WASH infrastructure development, particularly in developing countries and fragile contexts.
