City of Santa Ana, CAI WATER RATE STUDY <br />• CIP Project Identification: individual CIP projects identified based on high -risk assets and /or <br />assets that are in close proximity. Pipe segment identification, budgets and schedules often <br />differ from the previous lists due to logical regrouping of assets. For example, it makes more <br />sense to inspect or replace an entire continuous stretch of pipe even though the risk <br />prioritization may have scheduled specific segments to have been done at different times. <br />Therefore a single project will likely have segments with differing risk strategy group <br />assignments. <br />Note: risk prioritization and R &R replacement planning was based on existing data provided by the City. <br />Although the source data is believed to be the best available it may not reflect current conditions of all <br />facilities. Additionally, recent R &R activities may have already addressed some of the issues identified. <br />Therefore, recommendations should be verified with current R &R records and /or pipe inspection prior <br />to actual replacement. <br />BRE REPLACEMENT PRIORITIZATION <br />Using the results of the BRE analysis and replacement costing table, each water main pipe segment was <br />ranked from highest to lowest risk and assigned a replacement cost estimate. A partial list (risk scores of <br />50 or higher) of water main pipeline segments ranked by BRE score is included in Table C - 2 below. This <br />list includes the top 146 of the 21,477 total ranked records. <br />Table C -2: Partial List of Water Main Pipe Segments Ranked by BRE Score <br />Rank <br />1 <br />Unique <br />Pipe ID <br />4875 <br />Material <br />DI <br />Size <br />(in) <br />24 <br />Year <br />Installed <br />1970 <br />Decade <br />1970s <br />Length <br />0.07 <br />Cohort <br />5 <br />PoF <br />10.0 <br />CoF <br />10.0 <br />100.0 <br />Estimated <br />$190,577 <br />2 <br />11288 <br />CMLC <br />36 <br />0 <br />UNK <br />0.77 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$2,464,515 <br />3 <br />11296 <br />CMLC <br />36 <br />0 <br />UNK <br />0.04 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$133,496 <br />4 <br />11302 <br />CMLC <br />36 <br />0 <br />UNK <br />0.22 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$692,575 <br />5 <br />11308 <br />CMLC <br />36 <br />0 <br />UNK <br />0.35 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$1,130,456 <br />6 <br />11310 <br />CMLC <br />36 <br />0 <br />UNK <br />0.01 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$19,067 <br />7 <br />11326 <br />CMLC <br />36 <br />0 <br />UNK <br />0.31 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$986,112 <br />8 <br />11332 <br />CMLC <br />36 <br />0 <br />UNK <br />0.41 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$1,303,576 <br />9 <br />11337 <br />CMLC <br />36 <br />0 <br />UNK <br />0.29 <br />1 5 <br />10.0 <br />10.0 <br />100.0 <br />$930,778 <br />10 <br />11338 <br />CMLC <br />36 <br />0 <br />UNK <br />0.33 <br />5 <br />10.0 <br />1 10.0 <br />100.0 <br />$1,050,971 <br />11 <br />11339 <br />CMLC <br />36 <br />0 <br />UNK <br />0.26 <br />5 <br />10.0 <br />10.0 <br />1 100.0 <br />$818,127 <br />12 <br />11383 <br />CMLC <br />36 <br />0 <br />UNK <br />0.30 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$967,834 <br />13 <br />11401 <br />CMLC <br />36 <br />0 <br />UNK <br />0.03 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$93,426 <br />14 <br />11422 <br />CMLC <br />36 <br />0 <br />UNK <br />0.37 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$1,184,887 <br />15 <br />11423 <br />CMLC <br />36 <br />0 <br />UNK <br />0.30 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$970,724 <br />16 <br />11424 <br />CMLC <br />36 <br />0 <br />UNK <br />0.11 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$365,904 <br />17 <br />11425 <br />CMLC <br />36 <br />0 <br />UNK <br />0.31 <br />1 5 <br />10.0 <br />10.0 <br />100.0 <br />$997,434 <br />18 <br />11426 <br />CMLC <br />36 <br />0 <br />UNK <br />0.35 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$1,115,092 <br />19 <br />11427 <br />CMLC <br />36 <br />0 <br />UNK <br />0.40 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$1,271,689 <br />20 <br />11428 <br />CMLC <br />36 <br />0 <br />UNK <br />0.10 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$319,249 <br />21 <br />11444 <br />CMLC <br />36 <br />0 <br />UNK <br />0.10 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$318,859 <br />22 <br />11445 <br />CMLC <br />36 <br />0 <br />UNK <br />0.08 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$255,366 <br />23 <br />11446 <br />CMLC <br />36 <br />0 <br />UNK <br />0.07 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$224,415 <br />24 <br />11518 <br />CMLC <br />36 <br />0 <br />UNK <br />0.25 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$791,631 <br />25 <br />20333 <br />CMLC <br />36 <br />0 <br />UNK <br />0.00 <br />5 <br />10.0 <br />10.0 <br />100.0 <br />$7,989 <br />BLACK & VEATCH i Appendix C: ',I!
