1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop item is to provide the Board with updated information regarding the
SCADA Reliability Improvement Project.
2. HISTORY
The District has 5 electric and 55 water facilities located throughout our service
territory. These facilities include electric substations, pump stations, wells, storage
tanks and control valves. We communicate to these facilities over several types of
media including leased phone company data circuits, dial -up telephone lines, cellular
modems and a variety of radio systems. Starting in 2011, the District has installed
optical cables to many of these facilities in a systematic effort to replace older
communication media with a reliable and robust "future proof" technology. Optical
cables are immune to electromagnetic interference and have a virtually unlimited
lifespan. As technology and District needs change in the future, we can replace
electronic end use equipment without the need to replace the optical cables.
The SCADA Reliability Improvement Project (SRIP) is the overall project name given
to District efforts to replace antiquated communication media with optical cable
technology. Since 2011, the Board has approved and the District has successfully
completed 3 phases of this Project. The Phase 1 project included construction of
optical links from the District office to Martis Valley and Truckee Substations,
Glenshire Drive Well and Old Greenwood Well. The Phase 2 project connected the
District office and Richards Drive Pump Station, Donner Lake Tank, West Reed PRV,
and Wolfe Estates Hydro Station areas. The Phase 3 project connected the District
office with the Trails End Storage Tank, Prosser Heights, Prosser Village, Fibreboard
and Old Greenwood wells and China Camp Hydrostation.
A summary of SRIP projects by phase is shown in the table below:
No. Electric No. Water Optical
Facilities Facilities Cable

SRIP 1 2 2 37,200
SRIP 2 1 4 331500
SRIP 3 - 6 45,100
Totals 3 12 115,800
Staff is preparing bid documents for a contractor to procure, install, and test fiber optic
cables in a proposed Phase 4 project to extend optical cable between the Glenshire
Drive Well and Glenshire area. Facilities that will be connected in the Glenshire area
include the Glenshire Recloser, the Strand Pump Station, Well 20, and the Hirschdale
Well. In addition, this project will also fill gaps in our network by connecting two water
system control valves to existing optical cables installed in the Phase 1 project. These
two valves include the Gateway valve near the hospital and the Sierra College valve
located at the college campus entrance. We anticipate bringing the Phase 4 project
bid results to the Board for possible approval at the July Board meeting.
