The City of Sunnyvale Water SCADA System

Owner:
City of Sunnyvale, CA

Location:
Sunnyvale, CA
Project Description:
The City of Sunnyvale Water SCADA system is comprised of DYNAC® SCADA software running on dual redundant servers computers with 2 PC workstations communicating over a Fast Ethernet LAN located at the City's Corporation yard. The system communicates with 27 remote sites via licensed 450Mhz, 940Mhz & 900Mhz spread spectrum radios. The radios at the corporation yard are also installed in a dual redundant configuration.

Each remote site is equipped with a SCADAPack PLC/RTU that communicates back to the Corporation yard via radio system. The RTUs at the remote sites are used to control pumps, valves and other devices as well as to report information such as water flow and pressure back to the Corporation yard control center.

Video security surveillance cameras are also installed at 8 of the remote sites. Images from the cameras will be sent back to the Corporation yard via the licensed 940Mhz radio system for display on the DYNAC® operator workstations.
