BACKGROUND The disinfection of drinking water by public water agencies is essential in eliminating potential water quality problems. The City’s municipal water supply system permit from the Division of Drinking Water (“DDW”) 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 City of Arcadia Public Works Services Department (“PWSD”) to convert the disinfection system over to liquid sodium hypochlorite. Liquid sodium hypochlorite (commonly referred to as chlorine bleach) is much less hazardous to work with and has the same effect and residual protection as chlorine gas. The liquid sodium hypochlorite is delivered in bulk to the City’s well sites and stored onsite where it is then injected into the water distribution Purchase Order for Sodium Hypochlorite July 18, 2017 Page 2 of 2 system using precision metering devices to assure the proper concentration of disinfectant. Chlorine residuals are monitored on a daily basis by the City’s water Production Technicians. DISCUSSION In order to receive the best prices for sodium hypochlorite, the City conducted a formal bid process. A Notice Inviting Bids was published in the City’s adjudicated newspaper, and bid packages were sent to vendors who provide sodium hypochlorite to municipal water systems. On June 13, 2017, the City Clerk received 3 bids with the following results: Bidder Location Bid Amount Waterline Technologies, Inc. Santa Ana, CA $39,065.60 Fuller Engineering, Inc. Anaheim, CA $42,728.00 Univar USA, Inc. Santa Fe Springs, CA $45,971.84 All bid documents were reviewed for content and the contractor’s background was investigated.
