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.

This field guide is a practical tool for improving and maintaining drinking-water safety. It is designed to be used by YOU as a rural community member who shares responsibility for operation and management of the drinking-water supply in your community. It can also be used by YOU as a staff member o...f the local health or water supply office, local government authority, nongovernmental organization (NGO) or other community-based organization that supports drinking-water safety in rural communities. Ensuring the safety of the community water supply is a daily job, and community members and other stakeholders have to work jointly to achieve this goal.

Drinking-water quality regulations and standards developed or revised in accordance with this guidance will reflect the best practices identified in the WHO Guidelines for Drinking-water Quality to most effectively protect public health. Moreover, the regulations and standards will consider local ne...eds, priorities and capacities to ensure that they are realistic and appropriate. Topics covered include:
- Guiding principles
- Getting started
- Selecting parameters and parameter limits
- Setting out compliance monitoring requirements

La quatrième édition des Lignes directrices de l'OMS pour la qualité de l'eau potable s'appuie sur plus de 50 ans d'orientations sur la qualité de l'eau potable qui font autorité en matière de mesures de santé publique lorsqu’il s’agit de mettre en place des réglementations et des normes... nationales pour garantir la sécurité de l'eau.
Ces lignes directrices s’adressent principalement aux responsables de la réglementation dans le domaine de l’eau et de la santé, aux décideurs et à leurs conseillers, et ont pour objectif d’aider lors de la mise au point de normes nationales. Elles sont aussi utilisées, ainsi que les documents associés, par comme source d’informations sur la qualité et l’hygiène de l’eau et sur les stratégies de gestion efficaces.

Using an ensemble of climate models and socioeconomic scenarios, WRI scored and ranked future water stress—a measure of competition and depletion of surface water—in 167 countries by 2020, 2030, and 2040. We found that 33 countries face extremely high water stress in 2040 (see the full list). We... also found that Chile, Estonia, Namibia, and Botswana could face an especially significant increase in water stress by 2040. This means that businesses, farms, and communities in these countries in particular may be more vulnerable to scarcity than they are today.

The guide is presented in two parts:
Part 1. Principles of Operational Monitoring: Describes the key principles of operational monitoring, alongside the types of operational monitoring that may be performed and the information required within an OMP.
Part 2. Operational Monitorin...g Plan Development: Describes the stepwise development of an OMP for a water supply system, including the source, water treatment, intermediate storage, distribution and household. For illustration purposes, practical guidance is provided using a specimen water supply system considered to be representative of a conventional small- to medium-sized supply in a lower resource setting. This template may be used to develop system-specific OMPs for individual water supply systems.

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.

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

Providing improved water supply to low-income urban communities is a difficult challenge faced by water utilities throughout Africa and Asia.
This guide provides an introduction to available options for serving these communities.
The guide draws on sector experience in general, and more particular...ly on WSUP’s extensive experience of implementing urban WASH programmes in sub-Saharan Africa and elsewhere.
