The work identified will be constructed by the Water Division's field forces. Once the new water pipelines are installed, Riverside Public Utilities (RPU) will be responsible for standard trench repaving per the County of Riverside standard. Near the end of pipeline construction, staff will solicit paving bids for paving the trench area through the Public Utilities Paving Contractor's Panel. A budgetary estimate for the paving work has been included in this authorization.
