, : 11 <br /> o Operational Storage <br /> o Equalizing Storage <br /> o Fire Flow Storage/Standby Storage (use greater of either if approved by local fire <br /> authority) <br /> o Dead Storage <br /> • Provide analysis for each pressure zone in the distribution system <br /> • Identify potential solutions to any deficiencies in storage <br /> • Determine the maximum number of ERUs that can be supplied by the existing storage <br /> • Develop listing of Capital Improvements (as required) <br /> 9.3 City Responsibilities <br /> 1. Provide uncalibrated model in H2OMAP Water <br /> 2. Obtain calibrated models from Alderwood Water and Sewer District, Mukilteo, and Silver <br /> Lake for inclusion in model <br /> 3. Provide staff knowledgeable in the operation of the water system for discussions with HDR <br /> personnel <br /> 4. Identify locations within existing system where pressure or flow problems exist <br /> 5. Work with consultant to determine appropriate locations for fire flow tests and recording <br /> meters. <br /> 6. Provide traffic control for fire flow tests. <br /> 7. Provide data from C-factor analysis collected during flushing program, if available. <br /> 8. Deliver information needed for initial C-factor determination (pipe material and age) <br /> 9. Assist in the verification of the allocation of demands. <br /> 10. Provide transmission line flows and reservoir levels on a maximum 15 minute interval for <br /> diurnal curve calculations, if available. <br /> 11. Work with local fire authority to authorize nesting of fire flow and standby storage <br /> 12. Assist in the development of the Capital Improvement Listing and Map Development. <br /> 9.4 Assumptions <br /> 1. Model will be provided in H2OMAP Water <br /> 2. Model provided by City contains all necessary pipes, pumps, and reservoirs <br /> 3. Alderwood Water and Sewer District, Mukilteo, and Silver Lake models are fully calibrated <br /> 4. No water quality calibration is included in this scope of work <br /> 5. Detailed system analysis information or maps judged to be important to system <br /> vulnerability will only be included in the working draft and will not be included in the final <br /> system description. <br /> 6. IDSE simulations are not included in this scope of services. Should the City elect to add <br /> IDSE model simulations, a scope of services and budget will be developed for City <br /> approval. <br /> Everett Comprehensive Water Plan April 15, 2005 <br /> Exhibit A—Scope of Services 1 9 Page 14 of 21 <br /> � <br />
