Transcription

1 Cal WARN Mutual Aid Response: East Bay Municipal Utility District Resource Deployment Allen Goodson Manager, Operations & Maintenance Planning East Bay Municipal Utility District Raymond Riordan CalWARN State Steering Committee Chair Computer Sciences Corporation

2 Objectives Provide three WARN response scenarios and results from actual response Small Resource deployment for short term up to 72 hours Medium - Specialized efforts lasting less than a week Large - Complex water system support deployments Response to pre-warn events Lessons learned in each response Differences

3 EBMUD Supply and Service Area

4 EBMUD s Water Infrastructure Located in Oakland, California 1.3 million customers 325 sq. mile service area 152 pressure zones 4000 miles of mains 5 treatment plants 246 distribution reservoirs 167 pumping plants 150 rate control stations/regulators

5 WARN: Small Response 2001, Sonora Fire Responder: EBMUD Sonora Water, Sonora, California Issue: Fire destroyed water delivery system, a wooden water flume, circa 1890 still in operation Objective: Provide potable water pumps, fittings and high pressure flexible hose to provide temporary water service Response prepared for deployment and cancelled due to policy decisions to drill for water

6

7 Lessons Learned High volume portable pumps As-build drawings and hydraulic information Hose deployment abilities Lack of planning

8 WARN: Medium Response 1998, El Nino Storms Responder: EBMUD Cal American Water, Carmel, California Issue: Transmission water main failure at bottom of steep canyon due to landslide, isolating large portions of their distribution system from supply and fire protection Objective: Install temporary mitigations, restoring domestic and fire feeds until long term capital improvements identified and completed Prevented precautionary evacuation of hospital

9

10 Medium Response Lessons Learned WARN agreement critical to response timing Pre-deployment recon is critical in right-sizing deployment As-build drawings and valve maintenance are critical Single point of MA management ensures continuity Flexible hose deployment can be accomplished almost anywhere

11 WARN: Large Response 1994, Northridge Earthquake Responder: EBMUD LADWP, City of Los Angeles, CA Issue: Major earthquake causes significant damage to raw water, treatment and distribution infrastructure Objective: Provide self-sustained sustained and directed repair team of 15 personnel and 20 pieces of equipment with primary focus on 5 key distribution pressure zones

25 Large Response Lessons Learned WARN agreement vital Vehicle/equipment mechanics and fuel trucks are critical Must be self-sufficient sufficient Common communication devices vital Main break-to to-service failure ratio ranges from 1:5 (parallel) to 1:14 (perpendicular) Valve failure greater than 10% on mains perpendicular to forces Breakaway bolts on hydrants susceptible to failure Functioning air valves minimize main failures

26 Large Response Lessons 2 Distribution reservoir footings and valve pits Pressure zone sequence repair strategy is vital Residential home movement damages service laterals Mental fitness Single point of MA management ensures continuity Potable water deployment plan is critical

27 Localized Pre-WARN Deployment , Loma Prieta Earthquake Issue: Provide specialized equipment and personnel to the State of California (Caltrans) and the City of Oakland Objective: Support life-safety requests while sustaining fire-fighting fighting water system infrastructure repairs

38 Summary WARN agreement critical to operational response and recovery timelines Incident Command System invaluable Organizational value: Lessons learned from your deployments are vital to your own response and recovery planning Advanced planning on how you will quantify and manage incoming resources Next Presentation
