This interactive tool supports the implementation of the WSP step of hazard assessment by providing an overview of hazardous events, including those relating to climate change. The compilation was piloted and adapted based on experiences gathered, and aims to support practitioners, particularly water suppliers, health agencies and consultants, in implementing WSPs for climate resiliance. It was piloted in large (urban), professionally managed water supplies in limited resource settings, however, can also be applied and adapted for water supplies in other settings. This is not intended to be an exhaustive list, and may need to be adapted for application in the local context. It is intended to complement existing comprehensive guidance for implementation by providing a tool for practical application.
