6. TVMWD Imported Water Purchases – Water Supply Allocation Plan and
Calendar Year Data [2]
Staff informed that CY to date 2010 Three Valleys MWD has delivered 50K acrefeet,
with 20K acre-feet remaining to deliver prior to CY end. It is anticipated that
Three Valleys MWD will have surplus Tier 1 water available.
Four months into FY 2010-2011, a total of 26K acre-feet of WSAP water has been
delivered, with a remaining 45K acre-feet to be delivered by end of FY 2010-2011.
WSAP is currently trending comparable to FY 2009-2010 and it is anticipated that
the District will not exceed its allocation. MWD has estimated that for year two of
WSAP, based upon the final year one results, that the allocation has increased by
6K acre-feet. It is anticipated that there will be a surplus of WSAP water of
approximately 12K acre-feet.
7. Miramar Supervisor Control and Data Acquisition (SCADA) Programmable
Logic Controller (PLC) Replacement [1]
Staff informed the Committee that that the existing SCADA equipment is well
over ten years old and is now obsolete and only marginally supported by the
current software platform in use.
Staff has received a bid from its existing vendor, Prime Systems, Inc., for
approximately $100,000 to replace the SCADA PLC. The funding for this project
is budgeted for FY 2010-2011.
Discussion occurred regarding the pros and cons of continuing with Prime
Systems as a sole source vendor versus sending the project out for a competitive
bid, as well as policy considerations concerning this request. Some of the factors
staff conveyed included: the current vendor has been providing services for ten
years and has an intimate knowledge of Three Valleys operations as it relates to
its SCADA control functions. This is not something that can be easily duplicated
