PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt resolution authorizing City Manager to execute Task Order No.
40 with West Yost Associates, of Davis, for White Slough Water
Pollution Control Facility supervisory control and data acquisition
system upgrade, arc flash investigating and training, and preliminary design of odor control, electrical
building, and ultraviolet disinfection system communication improvements, in the amount of $660,010.
BACKGROUND INFORMATION: The City is currently in the process of conducting needed improvements
at the 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 50 -year-old facility up to current
standards.
This work includes two phases since the estimated cost of the improvements referenced above is
approximately $13 million. Funding for this work is available over the next several fiscal years in accordance
with the City's wastewater rate model projections. The initial phase includes 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. At this time, the initial phase is substantially complete.
The second phase includes the design and construction of SCADA improvements; construction of a coarse
screen system and septage receiving station, and replacing the existing south electrical building. The work
will also include an arc flash analysis of the facility and preparation of an electrical facility plan. The
estimated costs for this phase are expected to be $11 million. Final design and construction of this phase is
expected to take place during Fiscal Year 2018/19 through Fiscal Year 2020/21.
Task Order No. 40 includes engineering design, computer software and hardware, and training services
related to the implementation of SCADA system improvements. These improvements are next in priority and
are intended to replace the existing, obsolete SCADA software and hardware used to monitor and control
plant operations at the facility.

Task Order No. 40 also includes the preliminary design and construction cost estimates for the coarse
screening and septage receiving facility, a new south electrical building, and necessary improvements to
enhance communications between the ultraviolet disinfection system and the SCADA system. Preliminary
design of odor control improvements will be conducted as part of this task order because their location must
integrate with the other facilities mentioned above. Construction of odor control improvements is not planned
as part of this second phase of work.
Additionally, West Yost Associates will conduct an arc flash investigation of the existing electrical distribution
system. Arc flash occurs when the current from high amperage circuits diverts from its intended path toward
an alternate grounding source and can pose serious hazards to employees and equipment. City electricians
are trained to minimize this risk, but as facilities age, the potential for arc flash to occur can increase. This
task includes electrical distribution system modeling and arc flash hazard calculations, and electrical and arc
flash safety training for WSWPCF staff operators and electricians.
Staff recommends authorizing the City Manager to execute Task Order No. 40 with West Yost Associates,
of Davis, for White Slough Water Pollution Control Facility SCADA system upgrade, arc flash investigation
and training, and preliminary design of odor control, electrical building, and ultraviolet disinfection system
communication improvements, in the amount of $660,010.
FISCAL IMPACT:
Completing the second phase of work will enhance plant operations,
reduce employee exposure to potentially dangerous electrical conditions,
and will establish baseline design information for remaining facility
upgrades needed to bring the WSWPCF up to current standards.
FUNDING AVAILABLE: Funding for Task Order No. 40 is budgeted in Fiscal Year 2016/17
Wastewater Capital Outlay Fund (530).
