COUNCIL COMMUNICATION
AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for White
Slough Water Pollution Control Facility Electrical Building & Related Improvements
Project
MEETING DATE: May 18, 2022
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve Plans and Specifications and Authorize Advertisement for
Bids for White Slough Water Pollution Control Facility Electrical
Building & Related Improvements Project
BACKGROUND INFORMATION: The White Slough Water Pollution Control Facility (WSWPCF) South
Electric Building (SEB) 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 -1990 technology that are now obsolete
and both replacement parts and product support are 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.
The design of this facility (including delays associated with the COVID pandemic) has taken approximately
24 months to complete. The project includes the construction of all elements of the SEB including the
building structure, motor control centers, communication/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.
The construction work associated with this complex project is expected to take between 18 and 24 months
upon contract award. The schedule could be impacted due to lingering supply chain interruptions, and
long lead times associated with obtaining the specialty electrical equipment being installed. 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 2023/24
Staff recommends Council approve plans and specifications and authorize advertisement for bids for White
Slough Water Pollution Control Facility Electrical Building & Related Improvements Project.

The plans and specifications are on file in the Public Works Department. The planned bid opening date is
June 29, 2022. The project cost is not expected to exceed $12 million dollars. Project award is scheduled
for July 20th, 2022 with construction anticipated to begin this Fall.
FISCAL IMPACT: Relocating and updating the SEB will enhance overall treatment 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. Through prudent financial planning, funding for this
work is available over the next several fiscal years in accordance with the
City's wastewater rate model projections. The project does not impact the
General Fund.
FUNDING AVAILABLE: Funding is available from the Wastewater Enterprise Capital Fund and will be
identified at project award.
