A A T E R I E N E R G Y I L I F E <br />RIVERSIDE PUBLIC UTILITIES <br />Board Memorandum <br />P U B L I C U 7 I I I T I F 5 <br />BOARD OF PUBLIC UTILITIES DATE: AUGUST 14, 2023 <br />SUBJECT: CONSTRUCTION OF THE MARKET STREET WATER MAIN REPLACEMENT <br />PROJECT — WORK ORDER NO. 2223289 IN THE AMOUNT OF $1,186,000 <br />ISSUE: <br />Consider approval of Work Order No. 2223289 in the total amount of $1,186,000 for all <br />engineering, construction, paving and construction contingency costs for the Market Street Water <br />Main Replacement Project. <br />RECOMMENDATION: <br />That the Board of Public Utilities approve Work Order No. 2223289 in the total amount of <br />$1,186,000 for all engineering, construction, paving and construction contingency costs for the <br />Market Street Water Main Replacement Project. <br />BACKGROUND: <br />Aging and high risk of failure water pipelines are planned for replacement annually. These <br />pipelines are evaluated based on parameters such as pipeline age, construction material, and <br />maintenance records via a Business Risk Exposure (BRE) model. RPU staff created the BRE <br />model to identify high-priority water distribution pipeline segments needing replacement, and it <br />has proven valuable in identifying and prioritizing water main replacement projects. Details of the <br />BRE model and its use was presented to the Board of Public Utilities Water Committee on October <br />13, 2021. <br />This project is part of RPU's ongoing water main replacement program to replace old and high- <br />priority water mains. The project involves replacing an 8 -inch Matheson Steel water pipeline <br />installed in 1914, which has experienced over seven reported leaks since 1983. In addition, it is <br />a strong candidate for replacement based on age, construction material, and size. Replacement <br />of this pipeline will enhance the water system's reliability and fire flow in the area. Although this <br />pipeline does not directly serve the Riverside Community Hospital, pipeline failure in this area has <br />the potential to significantly impact traffic around and path of travel to the hospital facility. <br />DISCUSSION: <br />The work generally entails construction of approximately 1,200 linear feet of 12 -inch ductile iron <br />pipe, 15 water services, two fire hydrants, and five system connections, along with all necessary <br />fittings, appurtenances, and related incidental work, which will be installed according to RPU's <br />current standards. The Water Division's field forces will construct the work. Besides routine <br />
