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 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 document provides officials in developing countries with a manual that can assist in the planning of community piped water supply systems and is intended to be the basis for the preparation of country planning manuals. A checklist for planning and priorities for selection of projects precedes the elaboration of principles for planning. Principles include consideration of health, economic and social benefits; environmental and social constraints; and technical, economic, financial, logistic, institutional, and sociocultural considerations. The use of low-cost indigenous materials, simplicity for easy operation and maintenance, financial and institutional capacity, and community participation are emphasized. Project preparation, including project identification, pre-feasibility studies, monitoring and evaluation and technical planning are described. Technical subjects include water quality, system capacity, selection and development of sources, pumps, transmission lines, distribution networks, and water treatment. Attention is given to operation and maintenance, economic and financial considerations, logistic support, and local institutions, including human resources development.
