Seismic Practices to Improve Water System Resilience

Abstract eng:
The seismic resiliency of a water system dictates the seismic resiliency of an entire urban region. As a result, it is critical for water systems to rapidly recover from earthquake impacts. Unfortunately, most water systems are not designed or constructed to withstand earthquake forces. As a result, there is a strong need for water systems to manage seismic programs and implement seismic practices. The purpose of a water system seismic program is to ensure the safe provision of water following an earthquake. This purpose is realized through six goals, described in the paper, intended to make resilient water systems through reduced failure probability, reduced consequences from failures, and reduced time to recovery. This paper summarizes practices implemented by operational Water Systems worldwide to improve their seismic resilience and identifies several areas of needed advancement in this young field of practice. The information is useful for other infrastructure systems.
