Presentation for PDM Workshop summarizing key planning data and highlighting questions for <br /> discussion or confirmation. <br /> 3. Workshop agenda, notes, and responses to comments <br /> Task 12 Transmission and Distribution System <br /> Analysis <br /> 12.1 Objective <br /> Complete an analysis of pressure zone sources and storage facilities to identify deficiencies identify <br /> capital project needs, and develop preliminary sizing of proposed new or updated facilities. <br /> Use the City's existing InfoWater hydraulic model of the water system to identify hydraulic <br /> deficiencies, perform fire flow analysis, identify capital project needs, and develop preliminary sizing <br /> of proposed new or updated facilities. Update hydraulic components as required, and calibrate the <br /> existing InfoWater model based on hydrant test data. <br /> 12.2 HDR Services <br /> Storage Capacity Evaluation <br /> 1. Review City fire flow requirements. <br /> 2. Determine highest service elevation in each pressure zone. <br /> 3. By pressure zone, determine the required storage volumes for the following types of storage: <br /> a. Operational Storage <br /> b. Equalizing Storage <br /> c. Fire Flow Storage <br /> d. Standby Storage <br /> 4. Evaluate the existing storage capacity and compare it to the required storage based on <br /> projected demands. <br /> 5. Provide analysis for each pressure zone or pressure zone grouping in the distribution <br /> system. <br /> 6. Identify potential solutions to any deficiencies in storage. <br /> 7. Determine the maximum number of ERUs that can be supplied by the existing storage. <br /> 8. Develop list of projects for the Capital Improvement Program (if required based on results <br /> from analysis). <br /> 9. Determine depleted storage volume elevations for use in distribution system analysis: <br /> Everett Comprehensive Water Plan June 12, 2019 <br /> Exhibit A—Scope of Services Page 17 of 30 <br />
