City of Santa Ana, CA I SEWER RATE STUDY <br />Table A - 9: Asset Valuation by System <br />Sewer $499,433,649 $232,229,889 46% <br />1. Replacement Costs (in 2012 dollars) are calculated using the unit costs presented in within this report applied to all <br />assets Water and Sewer assets. <br />2. The asset valuation methodology (RCNLD) represents an estimate of total infrastructure value, accounting for <br />depreciation of assets. <br />A comparison of the current infrastructure value with the total replacement cost in Table A 9 is an <br />indicator of overall infrastructure age, and represented as a Value Ratio. The value ratio is calculated as <br />the Asset Value divided by Replacement Cost. <br />Total System Capital Asset Schedule of R &R Needs <br />Using the R &R needs forecasting methodology described previously, Figure A 1 illustrates the overall <br />R &R needs identified projected over a 30 -year period, beginning with FY2013 for the combined Water <br />and Sewer Enterprises. <br />Figure A -1: Annual Capital Asset R &R Needs for Water and Sewer Assets over 30 -Year Period <br />*Costs have been escalated to the year of R &R, using a 3% escalation from FY2013 <br />Observations <br />1. There were a significant number of assets that were modeled to be beyond their Class -Based <br />Useful Life (Approx $37M). Of this total, 99% are for Water and Sewer mains. <br />2. Of this 99 %, 76% are for Water mains, which have no condition assessment information (Approx <br />$28M). <br />3. R &R needs profiles for R &R vary considerably between Water and Sewer system assets. <br />BLACK & VEATCH I Appendix A: Refurbishment & Replacement Program <br />65B -222 <br />
