64 <br />SEWER RATE STUDY I City of Santa Ana, CA <br />Table A 10 summarizes the total funding needs identified during the 30 -year model period by <br />infrastructure group based on available information. <br />Table A - 30: Total Modeled R &R 30 Year Costs <br />Sewer Sewer $1,337,400 <br />Sewer Mains and Lift <br />Stations $118,765,100 <br />Total Sewer System $120,102,500 <br />*Costs have been escalated to the year of R &R, using a 3% escalation from FY2013 <br />As identified above, each system has a unique profile of Capital Asset R &R needs that is dependent on <br />overall age of the infrastructure, type of infrastructure assets (predominantly short or long asset lives), <br />and detailed asset knowledge as determined through inspections. Figure A 2 illustrates this unique <br />profile for the Sewer system. <br />Figure A- 2: Annual Capital Asset R &R Needs for the Sewer System <br />*Costs have been escalated to the year of R &R, using a 3% escalation from FY2013 <br />As discussed earlier, R &R schedules derived using depreciation methodologies are a good tool when <br />condition assessment data is not available. For the City, some information for sewer mains exist and as <br />such, Black & Veatch made refinements to the schedules proposed above. R &R projections for all other <br />assets remain until the City has completed its condition assessment work for aboveground assets. <br />65B -223 <br />NOVEMBER 2014 <br />
