Department: Utilities
Cost Center: 6003
For Agenda of: 7/16/2024
Placement: Consent
Estimated Time: N/A
FROM: Aaron Floyd, Utilities Director
Prepared By: Miguel Barcenas, Deputy Director – Engineering and Planning
Shawna Scott, Special Projects Manager
SUBJECT: AUTHORIZATION TO ADVERTISE THE WATER TREATMENT PLANT
OZONE CONTAINMENT IMPROVEMENT PROJECT, SPECIFICATION
2001026
RECOMMENDATION
1. Approve the project plans and special provisions for the Water Treatment Plant Ozone
Containment Improvement Project, Specification Number 2001026; and
2. Authorize staff to advertise for bids; and
3. Authorize the City Manager to award the construction contract for the bid total if the
lowest responsible bid is within the available budget for the Water Treatment Plant
Major Equipment Maintenance Project; and
4. Authorize the City Engineer to approve Contract Change Orders up to the available
project budget; and
5. Find the Project categorically exempt from the California Environmental Quality Act
pursuant to State CEQA Guidelines Section 15301 and 15303.
POLICY CONTEXT
The Water Treatment Plant Ozone Containment Improvement Project (Project) is
consistent with the City adopted General Plan Water and Wastewater Element (WWE)
Goals A 2.1 and A 3.1 because maintenance of the Water Treatment Plant (WTP) is
necessary to ensure a long-term, reliable water supply and manage the City’s water
resources to meet both current and future water demand associated with development
envisioned by the General Plan.
DISCUSSION
Background
The City’s Water Treatment Plant was originally constructed in 1961. In 1995, a significant
upgrade to the plant was completed to meet changing water quality requirements. This
upgrade included installation of ozone generators and an ozone contact basin to provide
an ozone-based process in place of the traditional chlorine-based process to meet water
quality regulations.
Page 27 of 401
Item 6c
In March of 2023, another major upgrade project was completed that replaced older
disinfection equipment including replacement of the ozone generation system and added
additional source water capacities needed to enhance the treatment processes. Ongoing
maintenance of the facilities and equipment at the Water Treatment Plant is necessary to
prolong the useful life of the facilities and ensure staff’s ability to operate the plant and
treat water to State and Federal standards.
Starting in early October 2021, ozone started being detected in the Water Treatment Plant
Air Prep Room. The cause of the release and location of the ozone was identified through
field investigations, which traced the leak to the ozone contact basin and necessitated
inclusion of the ozone containment project within the Water Treatment Plant Major
Equipment Maintenance Project (Project Number 2001026) in the City’s Mid-year Budget
Review for Fiscal Year 2023-24.
The proposed ozone containment project will consist of the demolition of an existing riser
and valve box, construction of a new manhole and valve, interception of a 12-inch ozone
contact basin overflow pipe, redirection of an existing chemical main to the new manhole,
construction of fabricated metal shade structures, extension of existing concrete flatwork
to include stairs and extension of a walkway, and installation of hazard signs. All work will
occur within the existing Water Treatment Plant. As a result of the project, ozone gas
would be prevented from entering the manhole under normal operating and maintenance
activities and reduce potential risks to Water Treatment Plant staff.
Previous Council or Advisory Body Action
In June 2023, the City Council adopted the 2023-25 Financial Plan, which allocated
$189,000 in fiscal year 2023-24 and $180,000 in fiscal year 2024-25 for Water Treatment
Plant Major Equipment Maintenance (Project Number 99653 [2001026]).
During the Mid-Year Budget Review for Fiscal Year 2023 -24, the City Council approved
an additional $180,000 for Water Treatment Plant Major Equipment Maintenance
including water treatment plant ozone containment repairs.
Public Engagement
This capital project was included in the 2023-25 Financial Plan and Mid-Year Budget
Review which had extensive community outreach and afforded opportunities for the public
to review and comment on all capital projects.
CONCURRENCE
The Water Treatment Plant Supervisor concurs with the proposed scope and approach
of the ozone containment maintenance task.
Page 28 of 401
Item 6c
ENVIRONMENTAL REVIEW
The project qualifies for a Categorical Exemption to the California Environmental Quality
Act (CEQA) pursuant to State CEQA Guidelines Sections 15301 (Existing Facilities) and
15303 (New Construction or Conversion of Small Structures) because the project consists
of the repair, maintenance, and minor alteration of existing facilities and equipment, and
the construction of small structures within the Water Treatment Plant. The project would
not result in an expansion of the existing use of the facility, nor increase capacity.

Total $496,722.72 $216,000 $280,722.72 N/A
The 2023-25 Financial Plan includes $180,000 in fiscal year 2024-25 for Water Treatment
Plant Major Equipment Maintenance (Project Number 99653 [2001026]).
During the Mid-Year Budget Review for Fiscal Year 2023 -24, the City Council approved
an additional $180,000 for Water Treatment Plant Major Equipment Maintenance
including water treatment plant ozone containment repairs. The budget change was
identified as a one-time request that will address minor modifications to meet required
permit compliance for the water treatment plant. There is $496,722.72 remaining in the
Maintenance Project account, including $477,535.51 for ozone system maintenance,
inclusive of the ozone containment project. Therefore, there are adequate funds available
to construct the project and $280,722 would remain in the Maintenance Project account.
ALTERNATIVES
Deny the approval to advertise the project. City Council could choose to deny the
authorization to advertise this project. Staff does not recommend this alternative as the
maintenance project is necessary to address potential worker safety issues associated
with release of ozone within the Water Treatment Plant.

1.01 DESCRIPTION
This section generally describes the project and includes work sequence and schedule,
Contractor's use of premises, and maintenance and operation of existing facilities.
1.02 LOCATION OF PROJECT SITE
The project site is located at the City water treatment plant located on Stenner Creek
Road.
1.03 GENERAL NATURE OF WORK
The work involves construction of a new manhole, intercepting a 12 inch gravity drain
line, construction of fabricated steel structures, concrete flatwork, coring holes in ozone
contact basin, and installation of hazard signs. Work is to be performed within an active
water treatment plant.
1.04 HEALTH AND SAFETY
Work within an active water treatment plant presents a number of hazards including but
not limited to:
A.Exposure to Ozone Gas - The existing 12-inch overflow pipe from the ozone contact
basin is intended to convey accidental basin overflows to Manhole 11 (MH-11), and
could potentially convey ozone gas. Additionally, entry into the ozone contactor is a
confined space, and could potentially contain ozone gas
1.Contractor shall furnish and install PortaSens III Model D-16 portable ozone gas
detector by Analytical Technology Inc. and deliver to City at project completion.
2.Contractor shall continuously monitor ambient ozone concentration when workers
are in excavations, manholes, or ozone contact basins.
B.Exposure to Large Volumes of Water Passing Through Pipes and Manholes at the
Project Site - Filter backwash water with flow rates up to 12,000 gallons per minute will
pass through the 24-inch piping and MH-11 two (2) times per day without warning when
the plant is in operation. Entry or modifications to MH-11, including modifications to
the 12-inch ozone contact basin overflow pipe, are prohibited while plant is in operation
(Approximately 5:00 AM – 6:00 PM, Monday through Friday). Perform night work as
required, outside of regular plant operating hours.
C.Entry into the ozone contact basin is prohibited while the plant is in operation
(Approximately 5:00 AM – 6:00 PM, Monday through Friday). Only one train of the
Page 73 of 401
