SUMMARY:  The Monterey Peninsula Water Management District (MPWMD or District) has been developing facilities for full-scale operation of the Phase 1 Aquifer Storage and Recovery (ASR) Project in cooperation with California American Water (Cal-Am).  The Phase 1 ASR site, also known as the Santa Margarita ASR site, is located near General Jim Moore Boulevard and Eucalyptus Road in Seaside.  One of the key facilities at the site is the “chemical/electrical” facility building, which is currently under construction and scheduled for completion this year.  This new building will house all the permanent chemical and electrical control equipment for the two onsite ASR wells.  The District has solicited bids for the three principal components of the permanent electrical equipment for the building.  Issuance of contract awards for qualified bids from electrical manufacturers is scheduled for late October to enable this equipment to be ordered and manufactured as soon as possible, so the equipment can be installed and used during the upcoming Water Year (WY) 2011 injection season.  Bids have been solicited for three components of the building’s electrical equipment:

                        Component Description                                                Estimated Cost

1.               meter and main switchboard                                            $ 54,500

2.               variable frequency drive with transfer switch                    $ 91,000

3.               motor control center gear                                                $ 16,000

                                                                                                Total    $161,500

Separate bids have been requested for each component as manufacturers may not be able to supply all three components.  The estimated cost for the three components above is $161,500.  With a 10% contingency ($16,150), the total estimate is $177,650.


RECOMMENDATION:   District staff recommends authorization to award contracts for bids for the permanent electrical control equipment listed above for use in the Santa Margarita Phase 1 ASR facility building, for a not-to-exceed total estimated cost of $177,650.  The requested funding authorization includes a 10% contingency amount over the estimated cost, in the event that actual costs differ from the component estimates.  If approved, staff will proceed with processing contract awards for qualified bids to the successful electrical equipment manufacturers. 


IMPACT ON STAFF/RESOURCES:  Planning, design, construction and operation of the Phase 1 ASR Project facilities and initiation of the Phase 2 ASR expansion are ongoing significant staff commitments, as reflected in the District’s Strategic Plan.  Funds for this work are included in the MPWMD FY 2010-11 budget under Line Item 1-2-1 A.1 a (adopted June 21, 2010).


BACKGROUND:  The Santa Margarita Phase 1 ASR site is designed as a dual-well injection and recovery facility.  The facility building that is currently under construction will house all the necessary chemical and electrical control equipment needed for recovery of injected water from the onsite ASR wells.  The MPWMD and Cal-Am have coordinated on the design of this building in order to accommodate the additional equipment needs for ASR expansion to other sites within the Seaside Basin, consistent with Cal-Am’s Coastal Water Project plans.


The electrical equipment components described in this item are planned to be purchased and installed as soon as possible so that the ASR wells will be able to utilize this permanent equipment during the upcoming WY 2011 injection season.  The installation of this equipment will be done by separate contractor bid award.  The timing for purchase and installation of this equipment is critical as it is a necessary prerequisite before Pacific Gas & Electric (PG&E) will authorize installation of the new upgraded electrical transformer to be located at the new facility building.  The PG&E work is currently scheduled to take place in January 2011, but this schedule may have to change as it is staff’s current understanding that some of the electrical equipment may not be manufactured in time to meet this schedule.  This schedule will be confirmed once all bids are awarded and the equipment installation can be coordinated with PG&E’s transformer installation schedule.
