Approve Plans and Specifications and Authorize Advertisement for Bids for Well 7
Electrical I mprovements
August 5,2020
Public Works Director
RECOMMENDED ACTION Approve plans and specifications and authorize advertisement for
bids for Well 7 Electrical lmprovements.
BACKGROUND INFORMATION: Built in 1978, the motor controlcenter serving WellT is antiquated
and is in need of replacement to comply with current industry
standards. ln 1994, additional electrical upgradeswere performed,
including the installation of a standby generator to provide emergency power back-up for both Well 7 and
the Lodi Lake Storm Drain Pumping Station. Well 7 site location is shown on Exhibit A.
This project will complete the on-site electrical upgrades by adding a new motor control panel replacing
wire feeds to the pump, site lighting and site equipment/electrical controls, and other related work, all as
shown on the plans and specifications for the above project. The new pump motor control panel will
regulate voltage, provide better pump efficiency, and comply with current electrical standards.
The specifications are on file in the Public Works Department. The planned bid opening date is
September 2,2020. The project estimate is $90,000.
Square D is an American manufacturer of electrical equipment and a registered trademark of Schneider
Electric. On August 18, 1982, Council approved the standardization of Square D for low voltage panels
to be used in water wells, sewage and storm water pumps, park lighting and public buildings (Exhibit B).
ln compliance with the August 18,1982 Council action, the project specifications will require provision of
Square D (Schneider Electric) low voltage electrical panels.
FISCAL IMPACT: The project will have a minimal impact on total maintenance costs but
enhance the safety and reliability of the pumps served by the upgraded
electrical system.
FUNDING AVAILABLE: Funding will be identified at project award.

COUNCIL COMMUNICATION
SUBJECT: Standardization of Low Voltage Electrical Panels
RECOMMENDED ACTION: That the City Council standardize low voltage electrical
panels. The recommended standard to be manufactured by the "Square D" Company.
BACKGROUND INFORMATION: The City's low voltage electrical panels are used to
control equipment suc as water wells, sewage and storm water pumps, park lighting
and pub Ii_c_bua-l-dings. Generally, the Utility Department se -leets, purchases and
Installs the panels in these facilities for other City Departments-.
The cost of these panels is now exceeding the $5,000 informal-bld limit. Purchas-
Ing them under formal bidding would more than likely provide the City with panels
by many different manufacturers. A major problem with this is one of spare parts
availability. Electrical components are generally not interchangeable from manu-
facturer to_manufacturer. This would mean that the City would have to stock parts
for each specific panel; in many cases, duplicating parts of similar function.
Choosing a supplier based solely upon low bid would not solve the problem. 1t has
been the Utility Department's experience that of the six or so major electrical.
equipment manufacturers, none are consistantly low bidders on equipment. Factors
such as reliability, repair costs, serviceability. and parts availability play a
much larger role in keeping the equipment in service economl'cally.
The City currently has over 40 low voltage panels In operation Most of these
panels were manufactured by the "Square D" Company. They have proven to be of
high quality and excellent reliability. All contain components manufactured by
Square D" with parts readily available in Stockton or from the manufacturer.
Parts for older panels are likewise available or easily fitted with new style com-
ponents. Utility Department experience has shown that parts for other brand
name, older equipment are no longer available and that there are no reasonable
substitutes. The City Electrici=ans have noted that "Square D" panels require only
periodic maintenance and are well organized internally and easily serviced.
Many of these low voltage panels are not "off the shelf" items; they are built for
specific customer- application, thus it Ts necessary for the manufacturer to lay
out and design such panels. The "Square D" Company has engineering staff located
in Stockton, Sacramento, and Los Angeles and during the design stage their plan-
ning and design engineers have been readily available to City Staff providing
expert service. This has enabled the City to obtain many specialized, high quality,
low maintenance control panels.
APPROVED: I FILE NO.
