The City's groundwater delivery system conveys groundwater pumped from four (4)
existing wells in Fountain Valley to the 16th Street Reservoir. The 161h Street Pump
Station pumps water from the three (3) million gallon reservoir into the water distribution
system to meet demands and to Big Canyon Reservoir (BCR) for storage. The City, in
cooperation with Southern California Edison (SCE), recently performed an energy audit
of its current water wells and 161h Street pump station and found that significant energy
savings could be realized if pump motor and drive shaft improvements were done at
both the wells and the 16th Street Pump Station.
The City engaged the design services of Dudek and Associates to conduct a preliminary
evaluation of the water wells and 16th Street pump station to determine the necessary
improvements. The following improvements were recommended to meet the energy
saving project objectives:
A. 16th Street Pump Station Project Objectives:
o Improve the pump station's overall energy efficiency by replacing the solid
state soft start motor controllers of the two (2) pumps with variable

frequency drives. This will eliminate throttling of the pump control valves
(PCV's) thus saving electricity and reducing the City's electric utility costs.
U Install two new vertical turbine pumps at a lower horsepower but at a faster
revolution per minute to improve efficiency.
B. Dolphin and Tamura Water Well Project Objectives:
Replace each well site's solid state soft start motor controllers (two at each
site) with variable frequency drives. This will eliminate, throttling of the pump
control valves, thus saving electricity and reducing the City's electric utility
costs.
Replacing the soft - starters with Variable Frequency Drives (VFDs) will improve
operational efficiency and reduce energy consumption by eliminating throttling of the
PCVs. Because of the dramatic energy savings, Southern California Edison (SCE) will
provide an estimated $250,000 in rebates if the City proceeds with the project. In
addition, the on -going annual energy savings of the completed project will allow the City
to recoup its investment in less than three (3) years.
Dudek was authorized to prepare contract documents to accomplish the project
objectives noted above. Those documents were completed earlier this year and bids
were solicited. At 10:00 A.M. on May 7, 2013, the City Clerk opened and read the
following bids for this project:
The low total bid amount is 9.1 percent below the Engineer's Estimate of $850,000.
The low bidder, SCW Contracting Corporation, possesses a California State
Contractors License Classification "A" as required by the project specifications. A
check of the contractor's references indicates satisfactory completion of similar projects
for other public agencies. The work necessary to complete this contract consists of
installing six (6) new variable frequency drives (VFDs) on the City's four wells and two
of the five pumps at the 16th Street Pump Station. In addition; two new energy efficient
pumps will be installed at the 16th Street Pump Station.

Construction Support Services
A Professional Services Agreement (PSA) with Dudek and Associates was executed in
August 2012 that included preliminary design for the water wells and 161h Street Pump
Station and final design efforts for the water wells only for a total fee of $97,460. It was
determined that it would be more cost effective to complete the 16th Street Pump Station
improvements in concert with the wells. Amendment No. 1 to the PSA was executed in
February 2013 to include the necessary contract documents for the 161h Street Pump
Station and increased the compensation to $119,420.
The original PSA included some minor construction support assistance. However
based on the final completed design, additional construction support services are
needed to complete this project. Upon City Council approval, Amendment No. 2 to the
Professional Services Agreement with Dudek and Associates will be prepared on a form
approved by the City Attorney to increase the total not -to- exceed compensation to
$135,000.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this project exempt from the California
Environmental Quality Act ( "CEQX) pursuant to Section 15302 Class 2 (c) of the CEQA
Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no
potential to have a significant effect on the environment as the project is a replacement
of existing utility systems involving no expansion of capacity.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of
the meeting at which the City Council considers the item). The Notice Inviting Bids for
this project was advertised in the City's official publication and in construction industry
publications.
Prior to implementation, staff intends to notice adjacent schools, churches and
businesses.
