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 more

Safe Water School Training Manual
recommended
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 opportun
...
ities associated with these supplies therefore warrant explicit consideration in policies and regulations.
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.

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. more

Guidelines for drinking-water quality: Fourth edition incorporating the first and second addenda
recommended
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.

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. more

agement of the drinking-water supply in your community. It can also be used by YOU as a staff member of 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.

er supply. Sanitary inspections are a well-established and widely-applied practice. They can support 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.

ification processes. As background for the recommendations we first give an overview of the main water use categories in Myanmar. We then provide preliminary suggestions for typology criteria and indices for assessing ecological status in lakes and rivers in Myanmar. The typology factors and physico-chemical parameters are based on common used factors in the EU countries. The biological elements include phytoplankton and aquatic macrophytes for lakes, and benthic invertebrates for rivers.
