Water Quality Surveillance
Objective:
To promote public health, safety and welfare by ensuring quality standards of drinking water
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

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 numbe...r 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.

The Joint Monitoring Programme (JMP) report – Progress on household drinking water, sanitation and hygiene 2000 - 2020 – presents estimates on household access to safely managed drinking water, sanitation and hygiene services over the past five years, and assesses progress toward achieving the s...ixth sustainable development goal (SDG) to ‘Ensure availability and sustainable management of water and sanitation for all by 2030’.

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.

The Guidelines for drinking-water quality: small water supplies have been developed to address the needs and opportunities associated with small supplies to facilitate progressive improvement towards safe and sustainable drinking-water services for all. These Guidelines are based on the principal re...commendation in the World Health Organization’s Guidelines for drinking-water quality, and they provide guidance on applying that recommendation to small water supplies in particular. These Guidelines aim to help governments and practitioners improve the safety of drinking-water delivered through small supplies.

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.

The public health community has tried for decades to show, through evidence-based research, that safe water, sanitation, and hygiene (WASH) and clean cooking fuels that reduce household air pollution are essential to safeguard he...alth and save lives in low-income and middle-income countries. In the past 40 decades, there have been many innovations in the development of low-cost and efficacious technologies for WASH and household air pollution, but many of these technologies have been associated with disappointing health outcomes, often because low-income households have either not adopted, or inconsistently adopted, these technologies.

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.

WASH Ex-Post Evaluation Series - Water Communications and Knowledge Management (CKM) Project
This evaluation examines the sustainability of selected components of the USAID/Indonesia Environmental Services Program (ESP), which was implemented from 2004–2010. Among other objectives, this activ...ity sought to improve health and livelihoods of Indonesians through enhanced and expanded access to key environmental services.
Following up on the program seven years after it ended, this evaluation addresses the sustainability of ESP’s capacity-building efforts with Indonesian municipal water utilities, known as Perusahaan Daerah Air Minum (PDAM), and financial mechanisms to improve utility management and expanded water access in urban areas.
