The CDC report on Preventing Diarrheal Disease in Developing Countries highlights five effective household water treatment methods to reduce waterborne illnesses, which cause millions of deaths annually. These methods include ceramic filtration, sol
...
ar disinfection (SODIS), flocculant/disinfectant powder (PUR), household chlorination, and slow sand filtration. Each method varies in effectiveness, cost, and ease of use, with benefits such as pathogen removal, affordability, and scalability, but also challenges like maintenance, recontamination risks, and user acceptance. The report emphasizes the importance of safe water storage and education to maximize health benefits.

r sources. It highlights the importance of safe water, noting that contaminated water is a major cause of waterborne diseases such as diarrhea and cholera. Treating water at the household level is emphasized as an effective way to reduce health risks.
The document outlines several treatment methods, including boiling, which kills most pathogens; chlorination, which disinfects water by adding chlorine; filtration, which removes dirt and certain microbes using simple or advanced filters; and solar disinfection (SODIS), which involves exposing water in clear plastic bottles to sunlight for several hours to kill microbes. Additionally, it stresses the importance of safe water storage, such as using clean and covered containers to prevent recontamination, and practicing good hygiene, including regular handwashing and maintaining cleanliness around water sources.
By promoting these methods, the document aims to raise awareness and provide practical solutions for improving water quality at the household level, thereby reducing the spread of diseases and enhancing public health.

The importance of insecticide-treated nets, oral rehydration salts (ORS), breastfeeding, immunisation, hygiene, access to clean water, deworming and emotional care for child development is also emphasised. The practical advice provided helps families to create safer and healthier environments, and to recognise when medical help is needed.

manual, the term “safety” encompasses these three elements. Although the principles in this manual can be broadly applied to all types of drinking-water 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.

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.

Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe a
...
nd reliable services. The needs and opportunities 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.

processing. CCFH requested the Food and Agriculture Organization of the United Nations
(FAO) and the World Health Organization (WHO) to provide guidance 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.
