Subject: Consideration of a Purchase of Radios for the Water SCADA System
1. WHY THIS MATTER IS BEFORE THE BOARD
Board approval is required for expenditures in excess of $15,000.
2. HISTORY
In December 2004, the Federal Communications Commission (FCC) announced that
all radio licensees operating 25kHz (wideband) systems in the 150-174 MHz and
421-512 MHz bands must migrate to 12.5kHz narrowband channels by January 1,
2013.
In December 2012, District staff discovered that Truckee Donner PUD Water SCADA
radios would soon be out of compliance with the FCC narrowbanding mandate.
3. NEW INFORMATION
Current District Water SCADA radios operate at 452MHz wideband. These radios
violate the FCC narrowbanding mandate.
The FCC has noted it will remove wideband systems off the air after the deadline or
assess heavy fines. Radios operating on wideband may cause interference on
frequencies used for public safety.
Existing Water SCADA radios will need to be replaced and several radio models were
evaluated and tested to check compatibility with legacy SCADA equipment. These
new radios will have the capability to operate with both old and new Water SCADA
RTUs.
After evaluating several models, staff determined the Teledesign model TS4000 radio,
will work with the old SCADA RTUs and will also operate on the new Water SCADA
RTUs.
On January 17th the District went out to bid for replacement of 45 SCADA radios.
Four sealed bids were received and a bid opening was held on January 25th. A
summary of the bids is included in the following table. Sage Designs, Inc. from Mill
Valley, CA was the lowest responsive bid at $78,133.52.

4. FISCAL IMPACT

amount of $78,134 with a 10% change order authorization for an amount not to
exceed $85,947 excluding tax.
