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 $44,080
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 to be used for the disinfection of the City’s municipal water system.
Waterline Technologies, Inc. is reaching the end of their second purchase order
extension and has submitted a written offer to extend the existing purchase order for
one final year. Due to a manufacturer’s price increase, the contractor’s offer of
extension reflects a one-cent per unit price increase from last year’s extension. In
addition, the quantity of sodium hypochlorite to be purchased will increase by 2,000
gallons to account for the Live Oak Well returning to service in Fiscal Year 2020-2021.
This would bring the total purchase order to $44,080, a 10% increase from the last
purchase order extension of $40,112. This will be the contractor’s third and final
purchase order extension. All other terms and conditions of the purchase order will
remain in effect.
Based on the excellent level of service 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 to disinfect the City’s municipal water supply in the amount of
$44,080.

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 State
Water Resources and Control Board 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
Public Works Services Department (“PWSD”) to convert the disinfection system over to
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 stored
onsite, where it is injected into the water distribution system using precision-metering
devices to deliver accurate concentrations in accordance with DDW standards. The
City’s W ater Production Technicians monitor the chlorine residuals on a daily basis to
ensure levels are consistent and safe.
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 between 35,000 to 36,000 gallons of sodium hypochlorite. However, with the
completion of the Live Oak water treatment facility, Live Oak W ell is expected to be
brought back into service in FY 2020-21. Although the treated water from Live Oak Well
meets drinking water standards, the injection of sodium hypochlorite is necessary
protocol to offer residual disinfection properties as the treated water joins the City’s
distribution system. As such, an additional 2,000 gallons of sodium hypochlorite is
needed, bringing the total quantity for purchase to 38,000 gallons in Fiscal Year 2020-
2021.
Waterline Technologies, Inc. is reaching the end of their second 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 one-cent per gallon
increase, due to an increase in manufacturing costs. This will be the contractor’s third
and final purchase order extension with all other terms and conditions of the purchase
order to 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 Section 15061(b)(3) of the
Guidelines of 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 2020-2021 Water Operations
Budget for the purchase of bulk sodium hypochlorite.
RECOMMENDATION
It is recommended the City Council determine that this action does not constitute a
project and is therefore exempt under the California Environmental Quality Act
(“CEQA”); and 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 $44,080.
