The water safety plan (WSP) approach is widely recognized as the most reliable and effective way to consistently manage drinking-water supplies to safeguard public health. Since the introduction of WSPs in the third edition of the WHO Guidelines for Drinking-water Quality (GDWQ) and the International Water Association (IWA) Bonn Charter for Safe Drinking Water in 2004, a significant number of water suppliers have implemented WSPs and many governments are actively promoting their implementation and/or inclusion in national legislation. According to preliminary results from a recent WHO/IWA global survey on WSPs (or equivalent risk assessment and risk management approaches), more than 90 countries have implemented WSPs and nearly 70 countries have policies or regulations pertaining to WSPs in place or under development.
This WSP auditing guidance document contributes to a growing body of practical WSP tools and resources developed by WHO and IWA, in collaboration with a number of other key partners.
