  2. ACWD Service Area and Supply • 103 Sq. Mile Service Area • Serving Fremont, Newark, & Union City • Approx. 330,000 population • 50 mgd average production • range of demand approx. 30 mgd to 75 mgd • 3 sources of supply • Groundwater (30 %) • California State Water Project (50%) • SFPUC / Hetch Hetchy (20%)

  3. ACWD Service Area and Hayward Fault Location

  4. Max Credible Event: Our 2008 Seismic Vulnerability Study • ACWD can expect: • 1,500 to 2,000 pipeline failures leading to… • System “bleed-out” in as little as six hours • 250,000 residents without water • Loss of surface water supply sources (SWP and SFPUC) • Production facilities shutdown • Groundwater supply interruption due to power supply loss • Our primary focus will be to: • Repair our system (taking weeks to months)

  5. Regional and Statewide Water Sector Collaboration • Tangible successes to date • CalWARN Agreement • Mutual Aid amongst water & wastewater agencies • Annual exercises on sharing resources • B.A.E.S.I.C. • SF Bay Area large water agencies working together • Key contacts communication directory • Potable Water Procurement Guidance • Adopted by Cal EMA • More important efforts underway (Ed’s talk)

  6. Common Mission, Common Risks, Common Needs in Recovery • Our Mission: …to provide a reliable supply of high quality drinking water at a reasonable cost… • Regionally, a catastrophic seismic event will affect ALL water utilities with: • Failed pipelines • Interrupted sources of supply • Damaged production facilities • Ultimately… DENIAL OF SERVICE • And to recover, we will ALL need: • The ability to communicate • Key resources: People, Equipment, Power, Fuel • Clear access to affect repairs

  7. Forward Advance Down the Long and Winding Road… • The Bay Area Water Sector “Bus” is running strong and will continue to edge forward However… • Successfully maneuvering the rough stretches can only be done in “caravan” style

  8. The Bottom Line • Restoration of water service after disaster will take much longer without effective working partnerships and coordinated preparedness with our interdependent service providers • Remember: Water is Life
