City of Santa Ana, CA I SEWER RATE STUDY <br />INTRODUCTION <br />The final step in this assessment process is to calculate the overall inspection and replacement cost for <br />each asset. Average facility inspection and replacement cost look -up tables were used to determine <br />overall budgetary estimates and schedules (see Table C 1 below). Construction cost (2012 dollars) values <br />were based on an informal survey of Southern California utilities in recent years, and inspection costs <br />were based on estimates from nation -wide projects. Specific cost estimates based on experience in <br />Santa Ana were not available at the time of printing. Replacement costs were not specific to pipe <br />material, and replacement was assumed to be the same diameter. Pipe segments with a diameter of 0 <br />or unknown were replaced with a 6 inch pipe. Costs also assume basic construction practices, including <br />imported sand bedding and backfill, compaction, pavement removal, hauling, shoring, trench <br />excavation, testing and disinfection. <br />Table C -1: Sewer Pipe Inspection and Replacement Costs (2012 dollars) <br />BLACK & VEATCH I Appendix C Inspection and Replacement Cost Calculation <br />65B -266 <br />i� i <br />�I�f. <br />797�1YN1��[ K�S. ti.
