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. Storage tanks are required for collection of water from springs or water produced from continuous flow water... treatment systems, e.g. from upflow clarifiers or slow sand filters. There should be sufficient storage volume to store all water produced overnight, as this is unlikely to be collected by users during the night. Storage tanks also have secondary functions such as ensuring a constant water supply to treatment processes, providing a level of treatment by settlement of larger suspended solids and maintaining pressure in distribution systems

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.

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.

Technical Note: Cholera treatment facilities provide inpatient care for cholera patients during outbreaks. Proper case management and isolation of cholera patients is essential to prevent deaths and help control the spread of
the disease. Traditionally, these structures have been referred to as ch...olera treatment centres (CTCs) and
cholera treatment units (CTUs). CTCs are usually large structures set up at central level (e.g. urban areas),
while CTUs are smaller structures set up in the periphery (e.g. peri-urban or rural areas). CTCs/CTUs can
be set up as independent structures in tents or within existing buildings or wards of health structures.
Whatever the structure, the principles described in this document should be respected

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.

Safe drinking-water management must consider drinking-water quality, acceptability and quantity in the context of public health protection. In this manual, the term “safety” encompasses these three elements. Although the principles in this manual can be broadly applied to all types of drinking-w...ater supplies, the guidance is primarily intended for piped water supplies that are professionally managed (by a water supplier or equivalent management entity).The guidance may be applied to existing drinking-water supplies, or adapted for water supplies that are in the planning stage before construction.

Climate-induced water insecurity poses one of the biggest threats to humanity and will lead to more hunger, disease and displacement
Oxfam water engineers are having to drill deeper, more expensive and harder-to-maintain water boreholes used by some of the poorest communities around the world, mo...re often now only to find dry, depleted or polluted reservoirs.
Today, during World Water Week, Oxfam publishes the first of its series of reports, “Water Dilemmas”, about the growing water crisis, in large part driven by global heating from greenhouse gas emissions. The report describes how climate change will impact water security in different regions, leading to more hunger, disease and displacement.
Carlos Calderon, Humanitarian Advocacy and Partnerships Lead for Oxfam Aotearoa said, “This new Oxfam research is focused on the global Water, Sanitation and Hygiene (WaSH) situation, but it paints a picture that illustrates the complexity of elements that, combined, will continue to increasingly affect women, girls, boys and men in the decades to come. Changing weather, poverty, inequality, gender-based violence, political instability and conflicts are impacting the availability and quality of adequate water systems. All governments, particularly those from rich countries, should responsively take action at a global scale. The clock is ticking. Our children will judge us for our actions today, or for the lack of them.”

Fully functioning water, sanitation, hygiene (WASH) and health care waste management services are a critical aspect of infection prevention and control (IPC) practices, and ensuring patient safety and quality of care. Such services are also essential for creating an environment that supports the dig...nity and human rights of all care seekers, especially mothers, newborns, children and care providers.
WASH and waste services are also critical for preventing and effectively responding to disease outbreaks. The COVID-19 pandemic has exposed gaps in these basic services (Box 1). These gaps threaten the safety of patients and caregivers, and have environmental consequences, especially as a result of large increases in plastic health care waste. In short, WASH is a critical foundation for improving quality across the health system (1).
Many facilities lack plans and budgets for WASH, which has impacts on IPC. This lack of services, and of systems to improve them, compromises the ability to provide safe and quality care, and places health care providers and those seeking care at substantial risk of infection and loss of dignity. Unhygienic health care facilities without drinking water or functional toilets are also a disincentive to seeking care and undermine staff morale – these factors can have a critical impact on controlling infectious disease outbreaks.
Climate change and its impacts on WASH and health services, gender-specific needs, and equity in service provision and management all require rigorous attention, adaptable tools and regular monitoring.

A sanitary inspection is a simple, on-site evaluation (traditionally using a checklist) to help identify and support the management of priority risk factors that may lead to contamination of a drinking-water supply. Sanitary inspections are a well-established and widely-applied practice. They can su...pport water safety planning, and in some contexts, may be a simplified alternative to water safety plans.
This publication presents the World Health Organization’s (WHO’s) sanitary inspection packages. These packages update the sanitary inspection forms in WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. With more than 25 years of practical experience with the application of sanitary inspections, these packages have been developed from a comprehensive evidence review and established good practices.

Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe and reliable services. The needs and opportunities associated with these supplies therefore warrant explicit consideration in policies and regulati...ons.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.
