Waterline Technologies, Inc. is reaching the end of their second extension and has submitted a written offer to extend the existing purchase order an additional year with no increase in pricing. This is the last extension to the purchase order and all other terms and conditions will remain the same. Based on the excellent services provided by Water Technologies, Inc., it is recommended that the City Council authorize and direct the City Manager to approve a one year extension to the purchase order with Waterline Technologies, Inc. for the purchase and delivery of sodium hypochlorite for the disinfection of the City's municipal water supply in the amount of $49,785. DISCUSSION The disinfection of drinking water by public water agencies is essential to eliminating water quality problems. 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 ( "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 and it has the same effect and residual protection as Extension of Sodium Hypochlorite Purchase Order June 2, 2015 Page 2 of 2 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 distribution system using precision metering devices to assure the proper concentration of disinfectant. These concentrations are monitored on a daily basis by the City's Water Production Technicians. On June 19, 2012, the City Council approved a purchase order with Waterline Technologies, Inc. for the purchase and delivery of sodium hypochlorite for the disinfection of the City's municipal water supply. Annually, the City purchases approximately 40,000 gallons of sodium hypochlorite. Waterline Technologies, Inc. is reaching the end of their second extension and has submitted a written offer to extend the existing purchase order for an additional year with no increase in unit cost. The contract language allows for annual contract extensions, subject to City Council approval. Waterline Technologies, Inc. has provided excellent service during the term of the contract. FISCAL IMPACT Sufficient funds have been budgeted in the Fiscal Year 2014 -15 Water Operations Budget for the purchase of bulk liquid sodium hypochlorite. Funds for the Fiscal Year 2015 -16 portion of the purchase order extension have also been included in the proposed budget. RECOMMENDATION It is recommended that the City Council approve a one year extension to the Purchase Order with Waterline Technologies, Inc. for the purchase and delivery of sodium hypochlorite for the disinfection of the City's municipal water supply in the amount of $49,785. Approved: Dominic Lazzar City Manager
