Presentation Transcript

  1. TACOMA WATER RESILIENCY Providing Clean, Reliable Water Now And In The Future.

  2. Built-in Resiliency • Resiliency in Sources and System • Reliable, high-performing system • Protected watershed • Redundant pipelines feeding City by gravity • Large groundwater source with actively managed groundwater protection • Extensive interties with other utilities

  3. Tacoma Water’s Supply System

  4. Source Resiliency • Surplus capacity • First and Second Diversion Water Rights, North Fork Wells • In-town groundwater sources

  5. Climate Change Resiliency

  6. Infrastructure Resiliency • Large, redundant storage reservoirs • High quality, long lasting materials for water mains • Looped distribution mains (where possible) • Buried, welded steel pump stations • Substantial portable power generation capacity

  7. Business Resiliency Asset Management Strategic Asset Management Plans • 18 Strategic Asset Categories • Using new maintenance strategies to focus work on critical, risk prone assets. • Starting a Strategic Maintenance Management Program. • Conducting Business Case Evaluations to determine which assets to rehabilitate (and when). • Reliability Centered Maintenance for some highly critical assets

  8. Work Force Changes
