FY <br /> a. Operational and equalizing storage depleted at current, 10-year, and 20-year <br /> planning horizons <br /> b. Operational, equalizing, and fire flow storage depleted at current, 10-year, and 20- <br /> year planning horizons <br /> Source Capacity Evaluation <br /> 1. Perform spreadsheet analysis of sources for each pressure zone in the distribution system to <br /> meet forecasted demands. Booster pump stations will be considered as sources to pressure <br /> zones. <br /> 2. Identify potential solutions to any deficiencies in sources. <br /> 3. Determine the maximum number of ERUs that can be supplied by the existing sources. <br /> 4. Develop list of projects for the Capital Improvement Program (if required based on results <br /> from analysis). <br /> Distribution System Analysis <br /> Model Review and Update <br /> 1. Receive existing, up-to-date InfoWater model from City and verify operability on HDR <br /> computers. <br /> 2. Meet with City operations and engineering staff to discuss system operational practices, <br /> such as pump operation rationale, areas of low pressures, reservoir operation philosophy, <br /> etc. <br /> 3. Perform initial review of model. Create a summary of questions and improvements for the <br /> model, and system design criteria that will be used in the model. Provide summary to City for <br /> review and comment. Design criteria will be used in the model to identify distribution system <br /> deficiencies. <br /> 4. Meet with City staff to discuss questions of model and have City staff provide overview of <br /> model. <br /> 5. Add to model planned improvement projects and system changes for future scenarios. <br /> 6. Perform high level verification that piping in model is currently up-to-date. It is assumed that <br /> the model is up-to-date for the current system and significant updates are not necessary. <br /> Any significant updates necessary will be completed by the City. <br /> Development of Model Demands <br /> 1. Review spreadsheet of customer demands provided by City for completeness and format <br /> spreadsheet as necessary for demand allocation work. Spreadsheet shall have all the <br /> information necessary to calculate the annual water demand by each meter(service and <br /> wholesale) in the system for the last three years, and include the customer class for each <br /> meter. <br /> 2. Calculate the 3-year average day demand for each meter. <br /> Everett Comprehensive Water Plan June 12, 2019 <br /> Exhibit A—Scope of Services Page 18 of 30 <br />
