MEETING DATE: MAY 18, 2010
TO: WILLIAM A. HUSTON, CITY MANAGER
FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER
SUBJECT: AUTHORIZATION TO AWARD CONTRACT FOR THE REPAIR OF
VANDENBERG WELL
SUMMARY
The Vandenberg Well recently experienced a mechanical failure. A detailed inspection determined
that the well pump, shaft and column pipe need to be replaced to make the well operable.
Competitive bids were solicited and received from qualified contractors and the contract is now
ready to be awarded to the lowest responsive/responsible bidder.
RECOMMENDATION
It is recommended that the City Council award the contract to the lowest responsive/responsible
bid submitted by General Pump Company and authorize the Director of Public Works/City Engineer
to expend a total of $103,000 for necessary repairs.
FISCAL IMPACT
Sufficient funds are available and budgeted in the FY 2009/10 Water Division Operating Budget to
compensate for this expense. Additionally, this repair expense may be partially reimbursed to the
City through the submittal of a claim to the City's insurance carrier for mechanical equipment
failure.
DISCUSSION/BACKGROUND
Vandenberg Well recently experienced an unexpected mechanical failure. The well was drilled in
March 1993 at a depth of 920 feet and equipped in 1995 to produce 1,500 gallons per minute
(gpm) of groundwater. It is an important groundwater producer for the western part of the City.
Upon pulling the pump and inspecting it for damage, it was discovered that the pump had
proceeded to seize during operation, most likely the result of normal wear and tear. The scope of
work needed to repair the damage incurred at Vandenberg includes installation of a new pump,
pump bearings, pump shaft and column piping. In addition, the well will be scrubbed and bailed to
well bottom. The well and all equipment shall be disinfected with chlorine and motor reinstalled,
tested and returned to operation.
Competitive bids were solicited from qualified contractors to make the necessary replacements and
repairs. A total of four (4) bids were received and tabulated below in the order of the least dollar
amount:
• General Pump Company ..............................................................................$103,000
• Palm Springs Pump & Drilling ......................................................................$113,741
• Zim Industries, dba Bakersfield Well & Pump Co .........................................$129,546
• Best Drilling & Pump Co ...............................................................................$135,421

All groundwater wells assist in the City's ability to adequately meet the operational, emergency and
fire flow requirements of the water service area. When any one well is off-line, the City must
compensate the ongoing water demand by purchasing more expensive imported water through
East Orange County Water District at approximately twice the cost it takes to pump groundwater.
In addition, with imported water being more restricted, it is imperative that the City maintain and
fully maximize its ability to deliver water from its own groundwater supply allocation.
It is recommended that the City Council award the contract for the repair of Vandenberg Well to
General Pump Company, the lowest responsive/responsible bidder. General Pump Company has
extensive working knowledge and is familiar with the set up of our wells and will allow us to return
the well to service in the most efficient time frame.
