RECOMMENDATION: That the Board of Public Utilities approve Work Order No. 2225902 in the amount of $234,000 for all engineering, construction, paving and construction contingency costs for the Monteel Place Water Main Replacement Project. BACKGROUND: Riverside Public Utilities (RPU) budgets annually to replace high-priority water pipelines that have reached their end -of -life. An end -of -life determination is based on parameters such as pipeline age, material, and maintenance records via a Business Risk Exposure (BRE) model, which identifies high-risk water distribution pipeline segments needing replacement. The BRE model has proven valuable in identifying and prioritizing water main replacement projects and was presented on October 13, 2021, to the RPU Water Committee. The Monteel Place Water Main Replacement Project was identified through the BRE model as an old, high-priority water main needing replacement. The current water pipeline consists of an existing 4 -inch cast iron water pipeline installed in 1963. Since 1997, the pipeline has experienced 14 leaks. Replacement of this pipeline will ensure water system reliability and increase fire flow in this area. DISCUSSION: The work generally entails the construction of approximately 435 linear feet of 6 -inch Polyvinyl Chloride (PVCO) pipe, 15 water services, one system connection, and all necessary fittings appurtenances, and related incidental work, which will be installed according to RPU's current standards. The Water Division's field forces will construct the work. Besides routine service tie - overs, there will be no disruption of service.
