These updated guidelines are intended primarily for decision-makers at national and subnational levels with responsibility for developing and implementing drinking-water quality regulatory frameworks and associated programmes for risk management and surveillance of small water supplies. This includes those supplies managed by households, communities and professional entities. The WHO guidelines provide a comprehensive overview of the health risks associated with drinking-water, the principles and approaches for ensuring its safety, and the practical steps to develop and implement water safety plans (WSPs). There is also guidance on assessing the enabling environment to inform planning and system strengthening, and on improving the use of data on small water supplies.
