PROJECT DISCUSSION
The Zone III and IV water pump stations are located at the City's Big Canyon Reservoir (BCR)
facility in Corona del Mar. The two pump stations boost water into the City's upper water
pressure zones from BCR. The Zone III station was used solely as a backup to the Metropolitan
Water District until the City reestablished its groundwater supply in 1997 through the
Groundwater Development Project. Now the Zone III pump station is used for continuous daily
service throughout the year. The station was constructed in the early 1960's. The pumps are
worn and responsible for significant energy losses. With the installation of the new Zone III and
IV electrical improvements and pumps, the energy savings that will be realized over the next ten
years should repay the cost of the project.
The project calls for the installation of the new pumps, motors and electrical controls to run both
the Zone III and IV pump stations. Variable frequency drives will be installed in the Zone III
pump station to provide a more energy efficient system for this pressure zone, which covers
one -third of the City. A backup generator is also being installed to provide emergency power to
the Zone III pump station. The Zone IV pump station is already equipped with a diesel driven
backup pump in case of a power failure.
By replacing the pumps and motors and utilizing the new variable frequency drives in the Zone
III controls, energy costs can be reduced by twenty -five percent. This equates to a yearly cost
savings of approximately $55,000.00.

ZONE III AND IV PUMP STATION ELECTRICAL IMPROVEMENTS
At 2:15 p.m. on June 12, 2001, the City Clerk opened and read the following bids for the Zone III
and IV Pump Station Electrical Improvement, C -3417:
BIDDER TOTAL BID AMOUNT
Low Rich Construction $609,654.00
2 Olsson Construction $698,185.00
3 Tamang Electric $773,898.00
4 Beador Construction $840,000.00
The low total bid amount is 1 percent above the Engineer's Estimate of $600,000.00. The low
bidder, Rich Construction, possesses the required Electrical Classification C -10 and General "A"
contractor's licenses. Rich Construction has satisfactorily completed the electrical portions of
the 16`" Street Reservoir and Pump Station project under the general contractor. They are
qualified to complete the requirements for this project.
ZONE III REPLACEMENT BOOSTER PUMPS
Staff requested bids from three pump manufacturers and four distributors. Since the City went
direct to the manufacturers for bids, only one distributor provided a bid (Beylick Drilling). By
ordering pumps directly from the manufacturer a significant cost savings can be realized. The
following were the bid results to supply four new replacement pumps for the Zone III pump
station, not including sales tax.
BIDDER TOTAL BID AMOUNT*
Low Sterling Peerless Pumps $129,036.00
2 Paco Pumps (Johnson Pump Company) $159,088.00
3 Beylick Drilling (Floway Pumps) $188,686.00
* Does not include sales tax.
There are sufficient funds available in the Water Enterprise Fund under Capital Project Account
No. 7503- C5500531 for award of Contract No. 3417 and for the purchase of the replacement
booster pumps.
