This tool is intended to support the practical application of the guidance presented in the Water safety plan manual: step-by-step risk management for drinking-water suppliers, second edition (WHO & IWA, 2023). Refer to Module 10 in the manual for detailed guidance.

This tool provides key questions and considerations for conducting successful water safety plan (WSP) reviews, including post-event reviews (e.g. following a significant incident, near miss or emergency). It can also support reviews with a particular focus on strengthening equity and climate considerations as part of continuous WSP improvement.
