RECOMMENDATIONS: That the Board of Public Utilities: Award Bid No. RPU -7602 for the Canyon Crest Area 2 Cable Rejuvenation Project to Southern Contracting Company, of San Marcos, California, in the amount of $496,666.65; and 2. Approve Work Order No. 1724058 in the amount of $746,000 for work associated with the Canyon Crest Area 2 Cable Rejuvenation Project. BACKGROUND: On June 25, 2018, the Board of Public Utilities (Board) received the Planned Routine Electric and Water Capital Projects Over $500,000 in Fiscal Year 2018/19 report. The report provides an overview of the routine infrastructure projects and highlights the importance of these capital improvement projects. Discussion of these projects provided context and familiarity to streamline Board approval of individual project actions throughout the fiscal year. One of the projects discussed was the planned replacement of obsolete High Molecular Weight Polyethylene (HMPE) Cable -In -Conduit (CIC) in the Canyon Crest residential service area to improve system capacity and reliability as recommended in the Electric System Master Plan (ESMP). This area has experienced the highest incidence of underground cable failures, over the past 10 years, and was prioritized for cable replacement to enhance electric system reliability. In 2016, as part of the cable replacement program, RPU completed a cable rejuvenation pilot project that tested and treated underground electrical cable to extend its useful life. Cable rejuvenation technology has been successfully used by other utilities as a substitute of cable replacement, which is less intrusive and more cost efficient. The cable rejuvenation process injects a special fluid into the cable to strengthen weak points and achieve service life extension. The process rejuvenates underground distribution cable by filling voids in the cable's
