Design of Electrical Building and Related lmprovements ($1,355,628), and
Appropriating Funds ($1,500,000)
MEETING DATE: October 2,2019
PREPARED BY: Public Works Director
RECOMMENDED AGTION: Adopt resolution authorizing City Manager to execute Task Order No.
48 with West Yost Associates, of Davis, for White Slough Water
Pollution Control Facility Design of Electrical Building and Related
lmprovements, in the amount of $1,355,628, and appropriating funds in the amount of $1,500,000.
BACKGROUND INFORMATION: The City is currently in the process of conducting needed improvements
at White Slough Water Pollution Control Facility (WSWPCF). The
improvements include corrosion repairs to exposed concrete process
channels, installation of a coarse screen and septage receiving station, replacing the existing south electrical
building, and upgrading the existing supervisory control and data acquisition (SCADA) system; and other
instrumentation and electrical related upgrades needed to bring this 5O-year-old facilíty up to current
standards.
Due to the substantial cost and complexity of the overall project, and the impacts to the treatment process,
the project is broken up into multiple phases and prioritized based on various factors such as employee
safety, regulatory risk, and/or potential facility infrastructure failures. The initial phase included the
assessment and repair of corrosion damage to the headworks influent channels, domestic and industrial
pump discharge chambers, primary sedimentation basin influent channel, and other miscellaneous non-
submerged concrete in the primary sedimentation basin area. This phase was accepted by Council on
November 1,2017. The second phase of work included the engineering design, computer software and
hardware and integration services related to the implementation of SCADA system improvements to replace
the outdated system. This work is substantially complete.
The next phase of work includes the relocation of the existing South Electric Building (SEB) which was
constructed in 1990. The existing building is located downwind of the headworks facility and has been
subjected to poor air quality due to hydrogen sulfide gas exposure from the headworks. This has
accelerated corrosion of the internal switchgear, conduit, wire, and other electrical components of the SEB.
Additionally, the aged components of the SEB are based on pre-'t990 technology that are now obsolete and
replacement parts and product support is difficult to obtain. Considering the SEB and associated
infrastructure are the "central nervous system" of the treatment plant, relocating this building to a less
corrosive location, and updating the electrical components to current standards, is now the priority project.
By relocating the SEB to a more desirable location, the building can be constructed with minimal disruption to
plant operations. Once the new building is completed, power will be "switched over" to the new building and
the existing building will be decommissioned and repurposed for storage/machine shop purposes.

Adopt Resolution Authorizing City Manager to Execute Task Order No. 48 with West Yost Associates, of Davis, for White Slough Water Pollution Control Facil¡ty

Task Order No. 48 includes engineering design of all elements of the SEB including the building structure,
motor control centers, commun¡cation/security and switchgear systems, heating, ventilating and air
conditioning system, pad mount transformers, wire and conduit runs, and general site improvements such as
access, parking, fencing, underground utilities, and area lighting.
Task Order No. 48 also includes coordinating with Pacific Gas & Electric (PG&E) to reactivate the existing
PG&E service to the WSWPCF as a standby power source when power from the Northern California Power
Agency (NCPA) is not available. Generally, on an annual basis, NCPA power is unavailable for a period of
two to three weeks during times when the Lodi Energy Center and/or Steam lnjected Combustion Turbine
plant are down for maintenance. During this time, the Wastewater Utility must use its onsite backup
generator, and rent an additional generator as a backup to the onsite generator, in order to be compliant with
the City's Regional Water Quality Control Board requirements. Annually, the utility budgets $150,000 for this
event to be used for the generator rental and fuel costs. Reactivating the PG&E service is anticipated to
yield substantial savings an annual backup generator costs.
The engineering and design work associated with this complex project is expected to take between 12 and
18 months; construction is anticipated to take approximately 24 months after the contract is awarded. The
costs for both the design and construction of this project are programmed into the City's wastewater utility
rate model over the next four fiscal years, through Fiscal Year 2023124.
Staff recommends authorizing City Manager to execute Task Order No. 48 with West Yost Associates, of
Davis, for White Slough Water Pollution Control Facility Design of Electrical Building and Related
lmprovements, in the amount of $1,355,628, and appropriating funds in the amount of $1,500,500.
FISCAL IMPAGT:Completing this phase of work will enhance plant reliability, reduce
employee exposure to potentially dangerous electrical conditions, and will
reduce the City's exposure to regulatory violations due to electrical
system failures. Funding for this work is available over the next several
fiscal years in accordance with the City's wastewater rate model
projections.
