The manual is targeted at water suppliers and organisations supporting water safety planning programmes, including government agencies responsible for public health, or regulation and surveillance of drinking-water quality, nongovernmental or intergovernmental organisations. The guidance provides a broad range of examples and case studies from lower- to higher-income settings, highlighting practical solutions to real-world challenges from around the globe to help readers apply the guidance in diverse contexts.

This second edition streamlines guidance on the integration of climate resilience and equity into the water safety planning approach, to help support access to safely managed drinking-water services for all users, despite growing uncertainties from a changing climate.
