Background and Analysis:
Olympia's water system includes 12 drinking water reservoirs that are essential for maintaining system pressure, providing fire suppression capacity and ensuring emergency water storage. These reservoirs are critical to the reliable delivery of water to residents, businesses and emergency services. However, some of these structures were constructed prior to the adoption of modern seismic standards and are considered vulnerable to significant damage or failure in the event of a major earthquake.
As part of its ongoing asset management efforts, the City completed evaluations of most of these reservoirs to assess their structural condition and seismic performance. These assessments have confirmed the need for substantial upgrades to meet current seismic resilience requirements. Ensuring that all 12 reservoirs can withstand a major seismic event is crucial for public safety, emergency response readiness and post-disaster recovery.
At this time, the total funding required to bring all of Olympia's reservoirs up to current seismic standards is still being determined. Preliminary evaluations indicate that the cost will be substantial. As further engineering analysis is completed, staff will be able to deliver more detailed and refined cost estimates, along with an updated Capital Facilities Plan that includes a prioritized list of projects.
Given the scale of work and current funding levels, it is clear that a significant rate increase will be needed soon to adequately fund these necessary upgrades. Without additional investment, the City remai...
