SUBJECT: 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 $40,112
Recommendation: Approve
SUMMARY
On July 18, 2017, the City Council approved a Purchase Order with Waterline
Technologies, Inc. in the amount of $39,065.60 for the purchase and delivery of liquid
sodium hypochlorite that is used for the disinfection of the City’s municipal water
system. Waterline Technologies, Inc. is reaching the end of their Purchase Order and
has submitted a written offer to extend the existing Purchase Order for an additional
year. The contractor’s offer of extension reflects a 2.6%, or $1,046.40, cost increase
due to higher production and transportation costs. This will be the contractor’s second
Purchase Order extension and all other terms and conditions of the purchase order will
remain in effect.
Based on the excellent level of services provided by Waterline Technologies during the
previous year, it is recommended that the City Council approve a one-year Purchase
Order extension 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 $40,112.
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
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
On July 18, 2019, 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 supply. Annually, the City
purchases approximately 36,000 gallons of sodium hypochlorite. Waterline
Technologies, Inc. is reaching the end of their Purchase Order extension and has
submitted a written offer to extend the existing Purchase Order for an additional year.
The contractor’s offer of extension reflects a 2.6%, or $1,046.40, cost increase due to
higher production and transportation costs . This will be the contractor’s second
Purchase Order extension and all other terms and conditions of the purchase order will
remain in effect. Waterline Technologies, Inc. has provided excellent service during the
entire term of the purchase order.
ENVIRONMENTAL ANALYSIS
The proposed action does not constitute a project under the California Environmental
Quality Act (“CEQA”), and it can be seen with certainty that it will have no impact on the
environment. Thus, this matter is exempt under CEQA.
FISCAL IMPACT
Sufficient funds have been budgeted in the Fiscal Year 2019-20 Water Operations
Budget for the purchase of bulk liquid sodium hypochlorite.
RECOMMENDATION
It is recommended 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
$40,112.
