FOR THE PURCHASE AND DELIVERY OF SODIUM HYPOCHLORITE TO BE USED FOR THE DISINFECTION OF THE CITY'S MUNICIPAL WATER SUPPLY IN THE AMOUNT OF $42,891 Recommendation: Approve SUMMARY The disinfection of drinking water by public water agencies is essential to eliminating water quality problems. The City's water system utilizes liquid sodium hypochlorite to disinfect groundwater pumped from the groundwater basin. As such, the City recently went out to bid for vendors to deliver in bulk liquid sodium hypochlorite to the City's water facilities. It is recommended the City Council award a one year purchase order contract to Waterline Technologies, Inc. for the purchase and delivery of liquid sodium hypochlorite to be used for the disinfection of the City's municipal water supply in the amount of $42,891. DISCUSSION The disinfection of drinking water by public water agencies is essential in eliminating potential water quality problems. Chlorination is an acceptable method used by municipal water systems. The City's municipal water supply system permit from the California Department of Public Health (CDPH) specifies that the City's water system use chlorination as a means of disinfection. Gaseous chlorine had been the standard for municipal water disinfection for many years. However, safety concerns related to the hazardous and corrosive nature of chlorine gas prompted the Public Works Services Department to convert the disinfection system over to liquid sodium hypochlorite solution. Mayor and City Council June 19, 2012 Page 2 of 2 Liquid sodium hypochlorite (commonly referred to as chlorine bleach) is much less hazardous to work with than gaseous chlorine and has the same effect and residual protection as chlorine gas. The sodium hypochlorite is delivered in bulk to well sites and stored onsite where it is then injected into the distribution system using precision metering devices to assure the proper concentration of disinfectant. These concentrations are monitored on a daily basis by water technicians. Notices inviting bids were published in the adjudicated paper and bid packages were distributed to area vendors. The City Clerk publicly opened the following three sealed bids on May 8, 2012: Bidder Location Bid Amount Waterline Technologies Inc. Santa Ana, CA $42,891.00 Fuller Engineering, Inc. Anaheim, CA $44,370.00 Univar USA Santa Fe Springs, CA $64,753.55 The bid documents were reviewed for content and the background and competency of the lowest responsible bidder, Waterline Technologies, Inc., was verified. The business of delivering bulk liquid sodium hypochlorite is rather small, and there are only a few vendors who offer these services. The City has worked with Waterline Technologies Inc., and in the past, they have done an excellent job providing the City with this service. It is recommended the City Council award a one year purchase order contract to Waterline Technologies, Inc. for the purchase and delivery of liquid sodium hypochlorite to be used for the disinfection of the City's municipal water supply in the amount of $42,891. FISCAL IMPACT Sufficient funds have been budgeted in the Fiscal Year 2012-13 Water Operations Fund for the purchase of liquid sodium hypochlorite.
