W A T E R E H E R G Y L 1 F G RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: March 15, 2013 ITEM NO: 2 SUBJECT: CONSTRUCTION OF THE RIVERSIDE ENERGY RESOURCE CENTER RECYCLED WATER SERVICE—WORK ORDER NO. 1311852 ISSUE: The item for Board of Public Utilities consideration is approval of the capital expenditure in the amount of $198,000 to construct the Riverside Energy Resource Center Recycled Water Service. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $188,000 for Work Order No. 1311852 which includes all design, construction, contract administration, inspection and construction contingency costs for the Riverside Energy Resource Center Recycled Water Service. BACKGROUND: In 2008, the Board of Public Utilities approved a construction project involving the installation of a new recycled water pipeline in Jurupa and Payton Avenues to provide recycled water service in the surrounding area including the Riverside Energy Resource Center(RERC). The RERC facility utilizes recycled water to cool certain equipment, which augments power production and maintains emission levels below regulatory limits. With the completion of RERC Units 3 and 4, recycled water demands have almost doubled. This project will connect the recycled water pipeline located in Payton Avenue to the RERC facility and provide a second source of recycled water for RERC operations. This project should be completed prior to the upcoming summer season to ensure that RERC's operation will not be interrupted. For this reason, staff will solicit construction bids through the Riverside Public Utilities' (RPU) Contractor's Panel to complete the work. The project will include the installation of approximately 1,200 linear feet of 6-inch ductile iron onsite piping with its associated fittings and appurtenances. The existing recycled water supply will be maintained as a backup source and will augment water needs at the plant. FISCAL IMPACT: The total capital expenditure for Work Order No. 1311852 is estimated to be $188,000, as summarized in the following table: Description Cost Percent of Total Design $18,000 9.0% Construction $150,000 75.8% Construction Contingency $15,000 7.6% Construction Survey/Testing $5,000 2.5% Contract Management/inspection $10,000 5.1% Work Order Total $198,000 100.0%
