W A T E R E N E R G Y t I F F Em RIVERSIDE PUBLIC UTILITIES waBoard Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: June 7. 2013 ITEM NO: 3 SUBJECT: CONSTRUCTION OF THE CANYON CREST BOOSTER STATION REHABILITATION PROJECT— PHASE 1 —WORK ORDER NO. 1320705 ISSUE: The item for Board of Public Utilities consideration is approval of the capital expenditure in the amount of $262,500 to construct the Canyon Crest Booster Station Rehabilitation Project — Phase 1 (PRV Relocation). RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $262,500 for Work Order No. 1320705 which includes all design, construction, paving, contract administration and construction contingency costs for the Canyon Crest Booster Station Rehabilitation Project— Phase 1. BACKGROUND: The Canyon Crest Booster Station was constructed in 1962 and needs to be rehabilitated. Within the booster station are pressure reducing valves (PRVs), which provide water to the Canyon Crest 1300 Zone. Because the PRVs rely on the pressurized water within the station, they will not function when the booster station is taken out of service for rehabilitation work. The PRV Relocation will move the PRVs to a new location (Attachment 1). This will provide an immediately reliable source of water for the Canyon Crest 1300 Zone and will allow the booster station to be isolated for rehabilitation work (Phase 2). Staff will seek Board approval for Phase 2 at a future date; with an estimated project cost of $950,000. Even in the absence of Phase 2, staff would still recommend approval of this project as it increases the reliability of service to the Canyon Crest 1300 zone. The project includes installation of approximately 400 linear feet of new 8-inch ductile iron pipe, construction of a new underground vault, installation of new 6-inch and 3-inch PRVs, a flow meter, and related appurtenances. The PRV relocation work will be performed by Riverside Public Utilities' (RPU) Water Division field forces. Once the new water pipelines are installed, RPU will be responsible for standard trench repaving in accordance with Public Works paving standards. Due to the relatively small size of the project area, the trench resurfacing work will be performed by the Public Works Department Streets Division. However, if the backlog of streets division projects precludes the paving to occur on schedule, staff will solicit paving bids from RPU's Contractor Panel. A budgetary estimate for the paving work has been included in this authorization.
