FINANCIAL STATEMENT The anticipated total expenditure for this project is $2,027,643 for the construction award, contingency, support services, and other miscellaneous costs. A total of $1,105,911 is budgeted in the Capital Improvement Program, leaving a project shortfall of $921,732. Staff recommends the allocation of $645,212 from the Water Replacement Fund (Fund 421) and $276,520 from the Water Expansion Fund (Fund 422) to cover the project shortfall. The funding and anticipated project expenditures are detailed in Attachment 1. BACKGROUND The City has historically experienced water quality issues associated with nitrification during the summer and fall months within the potable water distribution system. The City contracted with Carollo to investigate the possible reason(s) for nitrification. After an intensive sampling program in 2019, it was found that the cause of nitrification was the reduction of chloramines (used to disinfect the water) to unacceptable levels. Chloramines are introduced by Zone 7 at their Del Valle Water Treatment Plant and Zone 7 groundwater production wells, as well as at city-owned groundwater production wells. However, these chloramines slowly degrade the longer water resides in the distribution system. Working with the City's Utilities Division staff, Carollo recommended chloramine levels to be boosted within the City's distribution system and identified the Sycamore and Foothill Reservoirs as the optimal locations to introduce the chloramines based upon system operational practices. As the mechanism to introduce the additional chloramines, Carollo recommended installation of a Residual Control Systems (RCS) at the Sycamore and Foothill Tank Reservoirs. The City then contracted with Carollo to prepare plans and specifications to purchase and install the RCS equipment. The total design cost of$95,911 was funded through the Bi-Annual Water Quality Improvements Project, CIP No. 17100, with another $10,000 expected to be invoiced by Carollo for their work supporting the bid phase of the project and charged against CIP No. 17100. The plans and specifications were completed in December 2020 and the project was advertised to request construction bids on January 7, 2021. Two pre-bid meetings were held for the project: one on January 19, 2021, and the other on January 22, 2021. In accordance with the bid documents, attendance at one of the two pre-bid meetings was required for a contractor to submit a responsive bid. The pre-bid meetings were attended by 11 contractors. Two addendums were issued, providing supplemental information as was requested by bidders at the pre-bid meetings. The bid period closed on January 29, 2021, with eight contractors submitting a bid by the bidding deadline. DISCUSSION The Sycamore and Foothill Reservoir Residual Control System Project includes procurement and installation of a pre-manufactured Residual Control Systems (RCS) from UGSI Solutions Company (UGSI), electrical system modification/installation, installation of fencing and general site improvements, and installation of piping at the Sycamore and Foothill Reservoir tank sites.
