Multi-Agency Response Guidance for Emergency Drinking Water What you need to know…

1. Multi-Agency Response Guidance for Emergency Drinking WaterWhat you need to know… 2008 Annual BASIC Meeting Irvine Ranch Water District May 14, 2008

2. Overview • The Effort Behind the Guidance • Recognizing the need • Outlining the problem statements/key questions • The process: stakeholders, workshops • Deliverables: • A more precise water system damage picture following a disaster • Revised guidance for procurement and distribution of emergency drinking water • Guidance Overview • Next steps – What’s Left to Do…

3. How we got here • Lessons learned from Katrina • December 2005 – BASIC takes on the problem • The need for alternative drinking water following a regional disaster in the Bay Area (i.e. major earthquake) • Understanding that our #1 water utility priority will be to repair and restore system • Desire to clarify alternative drinking water procurement and distribution responsibilities within California SEMS/NIMS structure

4. BASIC’s Action Plan • Determine the true risk from a large earthquake in the Bay Area • How much alternative water will be needed? • Partner with CA State OES • Outline how responsibility for procurement and distribution of alternative drinking water will change during the event • Determine how will FEMA fall into the equation

5. Determining the Need to Outline a Solution • The Assignment for each BASIC agency • Independently develop true risk and effect scenarios for how each of our systems would fare in a max credible earthquake • Based on these analyses, determine the quantities of alternative drinking water supplies we would expect to request from State OES • Bring in all Stakeholders to present our findings and open a planning dialogue (2-Day Workshop) • Commit to take a lead role in developing solutions to the problem statements

6. Earthquake Scenario Analysis • Each BASIC agency investigated the expected impacts of a max credible quake on the Hayward Fault (6.9M) • USGS Shake maps used for study • Existing emergency response plans considered • Objective was to determine the quantity of alternative drinking water that each agency would be requesting from OES for days 3 to 7 following the event • Presentation of findings prepared by each agency for 2-day stakeholder forum held on 04/12 – 04/13/2006

7. Hayward Fault Earthquake Scenario • Event Assumptions • Maximum credible (6.9 magnitude) North/South Hayward Fault event • 98% of ACWD service area projected to receive “Very Strong” to “Very Violent” shaking (source: ABAG Shake Maps)

8. ACWD Service Area and Hayward Fault Location

10. ACWD’s Damage Estimates • Production Facilities: • Production rate immediately cut to 50% • Loss of well production, SFPUC rate, treatment plants damaged • At least 3 critical large transmission mains with catastrophic failure at fault crossing • 500 AC pipeline main breaks throughout system • Estimated 300 - 6” line breaks • Estimated 150 – 8” line breaks • Estimated 50 – 12” line breaks • +/- 30,000 gpm instantaneous added demand

11. ACWD Alt. Potable Water Needs – Request Estimates to OES • Assumes limited available treated water storage availability and reduced production capacity • All available staff utilized for system repairs • Requests are for 1 gallon of water per person per day • Assumes all local supplies fully utilized or unavailable • Day 3: • 250,000 customers without water – 1.75 million gallons of drinking water requested (supply for next 7 days) • Day 10: • 150,000 customers without water – 1.5 million gallons of drinking water requested (supply for next 10 days) • Day 20: • 75,000 customers without water – 750,000 gallons of drinking water requested (Day 20 to Day 30)

12. April 2006 2-Day Forum • USGS Presentation (Quake Risk/Effects Scenario) • BASIC agencies presented damage assessments • Attended by California OES (State, Regional, and Local Operational Areas), CDHS, EPA, ABAG, USGS, and CUEA • Ultimately, 2.5 – 5 million gallons of alternative supply drinking water will be needed for days 3-7 after the event (depending on 1 or 2 gallons per person supplied) for BASIC agencies • Following the resource assessment presentation, an open forum stakeholder discussion took place • First step identified was to revise and amend 1996 potable water procurement plan

13. Accomplishments to Date • Each BASIC agency now has clearer picture of the damage assessment and emergency water needs following major seismic event • Revised and Amended Alternative Emergency Drinking Water guidance • Product of broad stakeholder participation • SEMS/NIMS compliant • A critical component for an effective response • Through coordination with CUEA, the guidance was signed by the Director of California OES for formal adoption on August 30, 2007

14. Multi-Agency Response Guidance For Emergency Drinking Water Procurement & Distribution 2nd Edition The Guidance • The Guidance Includes: • Preparedness steps for all stakeholders • Roles and Responsibilities for each stakeholder – Local Water Utility thru FEMA • Concept of Operation – SEMS/NIMS • Establishes a “Water Coordinator” for EOCs • Establishes concept of Multi-Agency Coordinating System (MACS) for drinking water • Flow Charts • Emergency Action Checklists for all agencies/responders
