A water utility's resiliency - the ability to provide an uninterrupted supply of safe, clean water - can be affected by natural occurrences such as earthquakes, drought, climate change and water quality conditions. The Water Supply Forum has embarked on a project to help water utilities in King, Pierce and Snohomish counties proactively evaluate the region's existing water supply systems resiliency and plan for potential water supply disruptions.
Phase 1 of this project was done in 2015-16, identifying key risks to water supply. These included risks related to earthquakes, climate change, drought, and threats to water quality that could have regional impact. Phase 2 was completed in 2018 and features more in-depth study of key topics, focusing largely on earthquake risks. Additional detailed information on appropriate approaches to climate change modeling, and response to water quality risks was also developed. The findings for both phases are listed to the right.
