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 />After the 5 -year period, the suggested CIP is split between annual R &R distribution system projects and <br />addressing non - distribution system (booster stations, reservoirs, etc.) assets. At a minimum, Black & <br />Veatch suggests that the City invest approximately $8 million annually into infrastructure needs. <br />Appendix D contains a suggested level of investment for non - distribution system assets. <br />As shown in Figure 4 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). The $888.8 million <br />value in Figure 4 represents the cost of repairing or replacing the portion of main impacted. It does not <br />represent the replacement cost of the entire system. <br />P,LACK & VEATCH I Water Rate Study <br />[INTENTIONALLY LEFT BLANK] <br />65B -39 <br />27 <br />
