SUBJECT: Resolution Authorizing Award of Contract for Recycled Water Pump Station
Upgrades Project
RECOMMENDATION
It is recommended that the City-Council approve the resolution authorizing the award of contract
for the,Recycled Water Pump Station Upgrades Project.
BACKGROUND
The City ofPetaluma's recycled water system was constructed in 1981 and modified in 2009
with the completion of the Ellis Creek Water Recycling Facility(ECWRF) to allow use of
tertiary treated wastewater forrecycled water. The system consistsof four pump stations and 12
miles of pipelines, delivering water to over 1,000 acres of land'. The system had previously
conveyed secondary treated wastewater from the oxidation ponds at Lakeville Highway to
agricultural land for irrigation;of vineyards, golf courses and agricultural lands. Recently, staff
installed a temporary connection to allow the ECWRF;tertiary filters to provide water to recycled
water users. Previously, tertiary water was used only at the ECWRF for plant processing and site
irrigation. During the dry-weather season, May 1 —October 31, the City is restricted from
discharging into the Petaluma River, thus tertiary treated wastewater is distributed to recycled
irrigation,customers. During the remaining 6 months, secondary treated wastewater is discharged
to the River. Recycled water accounts for up to 48% of the City's total annual effluent flow.
The proposed project will assist in the expansion of recycled water use within Petaluma city
limits, including an increase in the amount of"potable water offset" credits, while improving
delivery reliability to all users..The project will allow termination of secondary treated
wastewater for recycled water use and eliminate the use of two of the City's four recycled water
• pump stations for this purpose. The project location is shown on Attachment 2.
DISCUSSION 1
The project will modify two of the existing pump stations; upgrade a critical pressure reducing
station,rehabilitate mechanical, electrical and control systems; and, correct structural and HVAC

deficiencies. The plant's 3W Pump Station forxecycled water will be upgraded with anew
jockey pump for delivering.low flows for plant use. Other improvements inelude,an additional
variable-frequency drive, flowmeter and vault,;:and modifications to_piping.and valving to
accommodate offsite reuse. Improvements at Pump Station No. I include installation of a 20"
pipeline connection and a pond outfall. Booster Pump Station No. 2 will see HVAC
improvements. The construction project will include startup and testing of all systems, including
updating station programming.
The Notice Inviting Bids was issued on December 13, 2012. On January 23, 2013, three bids
were received as followings:
Name of Bidder Bid Total
Pacific Infrastructure Corp. $1;,189,000 Lowest Responsible Bidder
Arnold Construction Co. $1,320,000
Cats4U, Inc. $1,387,064
Engineer's Estimate $1,650,000
The lowest responsible bidder, Pacific Infrastructure Corporation (PIC), has performed similar
projects for the City of Petaluma, East Bay Municipal Utility District and the Las Gallinas
Sanitation District. Staff verified that PIC possesses a valid Class A California Contractor's
License, license number 799927, which expires on October 31, 2013, that qualifies PIC to
perform the work.
Construction is scheduled to begin in March of:2013 and to be completed in December of 2013.
It is anticipated that construction management, programming and inspection services will be
conducted by City staff with assistance by an outside consultant for electrical and mechanical
expertise, addressed by a separate agenda item.
The proposed action meets Council.Goals: "Plan for and implement priority capital projects as
funding permits" and "Lnprove and enhance fiscal stability and sustainability"
FINANCIAL IMPACTS
The total project budget for the Recycled Water Pump Station Upgrades Project (C66400902) is
$3,341,000 and'$450,000 has been expended to date forpre-engineering, assessments and
design. The actual construction costs are significantly less than originally budgeted due to a
favorable bidding climate and a 2012 project scope reduction to eliminate the secondary recycled
water component and serve all recycled water users using tertiary treated wastewater. The
savings, approximately $1 million, will remain in the project account until project closeout; at
which time balance will be returned to the Recycled Water CIP Fund. The following is a
breakdown of the project budget:
