SUMMARY
On June 4, 2024, the City Council approved a purchase order extension with Waterline Technologies, Inc. for the purchase and delivery of liquid sodium hypochlorite to be used for the disinfection of the City’s municipal water system. Waterline Technologies, Inc. has reached the end of their extended contract period and has submitted a written offer to extend for an additional year with no cost increase. This will be the third and final extension of the Purchase Order; all other terms and conditions will remain in effect.
Based on the excellent service provided in the previous year, 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 to disinfect the City’s municipal water supply in the amount of $136,434.37.
BACKGROUND
The disinfection of drinking water by public water agencies is essential in preventing water-borne diseases. 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 was 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, is also less hazardous to work with and has the same residual protection as chlorine gas. The liquid sodium hypochlorite is delivered in bulk to the City’s well sites and is stored onsite, where it is then injected into the water distribution system using precision-metering devices to deliver accurate concentrations, in

accordance with DDW standards. The City’s Water Production Technicians monitor the chlorine residuals on a daily basis to ensure levels are consistent and safe.
DISCUSSION
On May 17, 2022, the City Council approved a purchase order with Waterline Technologies, Inc., with three optional one-year extensions for the purchase and delivery of Sodium Hypochlorite, for the disinfection of the City’s municipal water system. On June 4, 2024, the City Council approved the second of three possible contract extensions based on the excellent level of service that was provided. Waterline Technologies, Inc. has submitted a written offer to extend the Purchase Order for an additional year with no cost increase. It is recommended that the City Council extend the Purchase Order with Waterline Technologies, Inc. for an additional year; this will be the third and final extension.
ENVIRONMENTAL ANLYSIS
The proposed action does not constitute a project under Section 15061(b)(3) of the California Environmental Quality Act (“CEQA”), as it can be seen with certainty that it will have no impact on the environment.
FISCAL IMPACT
It is expected that the City will purchase up to $136,434.37 in liquid sodium hypochlorite during the upcoming Fiscal Year, in order to maintain the system and have an adequate supply on hand. Staff will only purchase the amount necessary for the City’s water system and will be charged according to actual volumes acquired. Sufficient funds have been budgeted in the Fiscal Year 2025-26 Water Operations Budget for the purchase of liquid sodium hypochlorite.
RECOMMENDATION
It is recommended that the City Council determine that this action does not constitute a project under the California Environmental Quality Act (“CEQA”); and approve an 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 $136,434.37.
