The purpose of this project is to upgrade the Supervisory and Control and Data Acquisition (SCADA) system to allow for system-wide monitoring and control of remote facilities. The upgraded system, as well as additional monitoring and control facilities at several sites, will reduce the risks associated with unplanned outages, improve the efficiency of making planned outages, and generally improve the ability to remotely monitor and control system pressure and flow from a centralized location.

Description
The project primarily consists of:

• Establish a common software platform and migrate all elements to this platform.
• Connect existing flow meters and new pressure transmitters, and provide communication to SCADA master station at five major Bay Area Water Supply and Conservation Agency (BAWSCA) customer sites.
• Install pressure transmitters, perform piping modifications, and provide communication to SCADA master station at seven existing regulating valves in the City distribution system.
• Install new flow and pressure monitoring devices at 23 key locations in the City distribution system.

Scope Refinements

The original project scope prior to the project’s needs assessment included new equipment and improvements at numerous facility sites. However, during project planning it was determined that the current scope represents most critical system needs. In addition to this project, all WSIP projects include site-specific SCADA improvements as appropriate. In addition to the current scope, the project was originally anticipated to include the integration of security components at 14 critical sites. This integration has been transferred to the System Security Upgrade Project.
