City of Santa Ana, CA I WATER RATE STUDY <br />grouping projects by area. Based on criticality criteria (PoF and CoF), Black & Veatch developed a list of <br />projects to address immediate system needs over the next 5 years. <br />As shown in Figure ES 3 and explained in more detail in Appendices A through D, the City's water system <br />has approximately 0.08 miles ($0.2 million, 2012 dollars) of mains that are in extremely critical condition <br />(red zone - highest risk of failure). Examining the next tiers of criticality, the City has another 1.35 miles <br />($3.2 million, 2012 dollars) of mains in highly critical condition (gold zone), and 3.30 miles ($7.2 million, <br />2012 dollars) of mains that are danger of imminent failure (yellow and green zones). <br />Figure ES - 3: Criticality Heat Map Graphic by Cost (2012 dollars) and R &R Strategy Groups <br />10 <br />L <br />9 <br />M 8 <br />LL <br />4- 7 <br />O <br />6 <br />v <br />= 5 <br />0) <br />3 4 <br />41 3 <br />h <br />C 2 <br />O <br />V 1 <br />Probability of Failure <br />1 2 3 4 5 6 7 8 9 10 <br />MPFO.3 <br />$0.7 <br />$0.1 <br />$0.1 <br />$0.0 <br />$0.0 <br />$0.0 <br />$0.3 <br />$1.3 <br />$6.1 <br />$0.2 <br />$0.0 <br />$0.0 <br />$0.2 <br />$0.6 <br />$1.2 <br />$2.8 <br />$0.0 <br />$0.0 <br />$1.9 <br />$0.0 <br />$0.7 <br />$0.3 <br />$2.3 <br />$6.1 <br />$6.4 <br />$0.1 <br />$0.0 <br />$0.0 <br />$0.0 <br />$0.0 <br />$3.3 <br />$1.1 <br />$4.6 <br />$16.4 <br />$9.2 <br />$0.2 <br />$2.3 <br />$0.0 <br />$0.9 <br />$0.0 <br />$0.5 <br />$4.3 <br />$3.0 <br />$2.1 <br />$16.9 <br />$2.5 <br />$14.8 <br />$10.9 <br />.4 <br />$0.0 <br />$0.8 <br />$20.9 <br />$17.5 <br />$11.7 <br />$55.7 <br />$6.7 <br />$44.8 <br />$21.3 <br />0.9 <br />$0.9 <br />$5.4 <br />$4.1 <br />$1.9 <br />$3.9 <br />$22.0 <br />$1.2 <br />$4.8 <br />$3.1 <br />` $4.2 <br />$0.9 <br />$0.9 <br />$38.7 <br />$25.1 <br />$15.3 <br />$91.4 <br />$12.8 <br />$35.5 <br />$18.9 <br />$11.5 <br />$3.4 <br />$4.9 <br />$1.7 <br />$6.01 <br />$9.2 <br />$75.2 <br />1 $24.5 <br />1 $54.3 <br />$47.4 <br />$26.8 <br />$4.0 <br />$3.0 <br />Millions of Dollars <br />Extremely High Probabi l ity and Consequence <br />Very High Probability and Consequence <br />C High Probability and Consequence <br />D Moderate Probability and Consequence <br />E Extremely High Probability and Lowto Moderate Consequence <br />F High Probability and Lowto Moderate Consequence <br />Lowto Moderate Probability and Extremely High Consequence <br />Lowto Moderate Probability and High Consequence <br />y Unknown <br />Z Low Criticality <br />Total Cost: $888.8 <br />Table ES 1 summarizes the results of the preliminary asset condition evaluation and indicates that over <br />the next 5 years, the City should invest approximately $11.2 million (2012 dollars) in its water system to <br />catch -up with deferred activities (replacement of assets prioritized as "critical', "very high likelihood of <br />failure ", "high likelihood ", "very high consequence of failure' and "high consequence').
