Post-earthquake functionality of utilities (water supply and wastewater treatment) is vital to the seismic resiliency of communities. The operation of this critical infrastructure is fundamental to the social and economic vitality of society. This presentation will compare the lessons-learned from the 2017 Central Mexico earthquake and the findings from a recent systemwide seismic resiliency study conducted by the King County Wastewater Treatment Division and the Seattle Public Utilities’ water system. Find out how to identify vulnerabilities and risks, prioritize seismic hazard mitigation investments, and develop a plan for implementing mitigation strategies.

Learning Objectives:

1. Plan, design, and conduct a systemwide seismic resiliency study of interconnected public infrastructure and then, implement a combination of seismic standards that can be applied to evaluate systemwide seismic resiliency.

2. Discuss the importance of post-earthquake functionality of utilities by sharing lessons-learned from the 2017 Central Mexico Earthquake and comparing with recent studies in the Pacific Northwest.

3. Conceptualize and develop a framework for creating seismic resiliency plan.
