BACKGROUND: The San Bernardino Transmission Pipeline is an important facility for Riverside Public Utilities (RPU), as it delivers a significant portion of the City's water supply. This pipeline begins in the City of San Bernardino and makes its way southerly toward the City of Riverside through public street right -of -ways and easement corridors. It ultimately terminates at the Linden /Evans Reservoir Complex located at the corner of Linden Street and Cranford Avenue. This pipeline was originally constructed in the 1920's out of concrete pipe. Although many segments of this pipeline have been replaced over the years with Cement Mortar Lined and Coated Steel Pipe (CML &C), several segments of the original vintage concrete pipe remain. To better understand the overall condition of the remaining segments of concrete pipe and to assist with planning future replacements of these segments, RPU hired URS Corporation (URS) in 2011 to conduct an evaluation of these sections to determine their condition and likelihood of failing in the near horizon. URS' findings prioritized the pipeline segments and appurtenances in need of replacement or rehabilitation based on the risk of failure that each poses. The work of the subject project will cover the highest priority improvements identified. The lower priority improvements will be completed in phases, including the budget and work schedule at a future date; and coordinated with other capital projects, as appropriate. The work of the subject project will generally entail replacement of approximately 220 linear feet of existing concrete pipe with new 42 -inch CML &C Steel pipe along with all related valves, fittings and appurtenances. The work will also involve localized repairs to existing outlets and appurtenances at various locations inside the existing 42 -inch concrete pipeline in addition to all required pavement
