RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: August 2, 2013 ITEM NO: 5 SUBJECT: RAUB CHLORINATION RETROFIT PROJECT, BID NO. 1033-13-04 — REJECTION OF BIDS ISSUE: The item for Board of Public Utilities consideration is rejection of all bids for the Raub Chlorination Retrofit Project— Bid No. 1033-13-04. RECOMMENDATION: That the Board of Public Utilities reject all bids received for the Raub Chlorination Retrofit Project — Bid No. 1033-13-04. BACKGROUND: Riverside Public Utilities (RPU) protects the water system by injecting a small amount of chlorine near the well fields. RPU uses two sources of chlorine: one is a liquid sodium hypochlorite, which is delivered to the site by tanker trucks and stored in a tank; the other is an onsite generation unit that converts salt to sodium hypochlorite. Considering life-cycle costs, an onsite generation system is typically less expensive to own and operate than a liquid sodium hypochlorite system. The existing Raub Chlorination Station uses liquid sodium hypochlorite. The storage tank, where the liquid sodium hypochlorite is kept, is leaking and cannot be repaired. The building that houses the leaky tank was not designed to facilitate removing and replacing the tank without performing major improvements to the building. The leaky tank was isolated and taken off line. Staff provided a temporary storage tank and piping located outside the building while a permanent and feasible solution is constructed. As an alternate to replacing the liquid sodium hypochlorite tank, staff prepared plans to re-purpose and augment the existing structure for a proposed onsite generation chlorine unit. Bids were opened on June 14, 2013. For informational purposes, the three bids received were summarized in the table below: CONTRACTOR CITY LOCATION BID TOTAL 1 SCW Contracting Corp.
