RECOMTUIENDED AGTION: Adopt resolution authorizing City Manager to execute Amendment
No. 2 to 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 $110,000.
BAGKGROUND ¡NFORMATION: 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, upgrading the existing supervisory control and data
acquisition (SCADA) system, and other instrumentation and electrical related upgrades needed to bring
this S0-year-old facility 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. 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.
Task Order No. 40 (the next phase of work also nearing completion) includes engineering design,
computer software and hardware, and training services related to the implementation of SCADA system
improvements. These improvements are next in overall project priority and will replace the existing,
obsolete SCADA software and hardware used to monitor and control plant operations at the facility.
During the initial SCADA budget development, West Yost Associates made certain project budget
assumptions about the existing SCADA system based on its experience with other facilities of similar age
and configuration. The assumptions were necessary because the existing SCADA infrastructure is
embedded in old conduit and electric motor control centers throughout the treatment facility and it was
not practical to perform the complete infrastructure assessment prior to project budget development. As
the work progressed, it was found that several elements of the system are obsolete and no longer

supported; hardware controlling the various plant functions do not use consistent programming language
and naming conventions; Control Building wiring and facility infrastructure is in very poor condition, and
there is little reliable programming documentation requiring significant reverse eng¡neering effort to
ensure the new graphic interface is compatible with the existing system. Amendment No. 2 is necessary
to address the items above and will not to exceed $1 10,000, increasing the total contract amount to
$770,010.
Staff recommends authorizing City Manager to execute Amendment No. 2 to 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 $110,000.
FISCAL IMPAGT:This unplanned but necessary work is needed to complete the
SCADA system upgrade element of this contract. This additional cost
will not impact the General Fund.
FUNDING AVAILABLE: Funding for Task Order No. 40 is budgeted in Fiscal Year 2018119
Wastewater Capital Outlay Fund (53099000.77020) - $t 10,000
