Special Focus on COVID-19 The report provides updated estimates for drinking water, sanitation and hygiene in schools including progress from 2015 to 2019. It highlights the rapid improvement needed to ensure students have access to handwashing facilities with soap and water during the COVID-19 pandemic, and to meet associated SDG targets by 2030

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 needs, 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 requirement

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 number 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 practical guide for improving quality of care through water, sanitation and hygiene in health care facilities . WASH FIT is a risk-based, continuous improvement framework with a set of tools for undertaking water, sanitation and hygiene (WASH) improvements as part of wider quality improvements in health care facilities. It is aimed at small primary, and in some instances secondary, health care facilities in low and middle income countries. An app, for front line data collection is also available in the Android Google Play store or as a web ap

Le présent guide pratique explique ce qu’est un plan de gestion de la sécurité sanitaire de l’eau (PGSSE) et de quelle manière celui-ci peut vous aider à renforcer la sécurité sanitaire de votre alimentation en eau potable, notamment par une amélioration progressive, étape par étape et quotidienne de votre système. Il vous fournit une gamme de modèles prêts à l’emploi pour vous aider à concevoir votre propre PGSSE. Les conseils prodigués et les modèles fournis vous aideront à prendre conscience de la facilité avec laquelle un PGSSE peut être mis en œuvre et vous permettront de mettre en place des améliorations rapidement.

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 Monitoring 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

This guide is intended for people involved in the management and operation of small- to mediumsized organized water supply systems. The content has been developed with particular consideration for operational-level personnel with responsibility for chlorination (for example, water treatment plant operators and technicians). The material presented within this guide may also be relevant for engineers and representatives from public health, local government, non-governmental organizations, as well as any other individuals supporting water safety planning activities for the supply of safe drinking-water.
Part 1. Chlorination principles: Describes key chlorination concepts, providing a knowledge foundation for the implementation of effective chlorination practices.
Part 2. Chlorination practices: Describes the practical application of the concepts presented in Part 1, including calculations and procedures for safe and effective chlorination of drinking-water supplies.
