The document is intended to provide guidance to water suppliers and Water Safety Plan (WSP) teams who have already adopted the WSP approach and are developing and implementing WSPs. It aims to enhance their understanding of climate change and how it can be integrated into the WSP process. The guide covers various topics, including the broader issues of climate change, regional climate vulnerability assessments, disaster risk reduction, and integrated water resources management. The approach for integrating climate change considerations into WSPs may vary depending on local circumstances. Therefore, the guide offers general guidance and recommends tailoring the WSP approach to local conditions.
