SOUTH BAYSIDE SYSTEM AUTHORITY (SBSA)
	Control System Design & Integration Services
	SBSA is a publicly-owned treatment works located in the San Francisco Bay Area. They provide wastewater transmission and treatment for three municipalities and another sanitary district.

Issue
SBSA needed a long-term solution for reliable and cost-effective implementation of process control and instrumentation systems. These systems monitor, control and automate SBSA’s regional wastewater treatment plant and pump stations. Rather than a conventional, design-bid-build solution, SBSA wanted to build the systems in a phased approach which spread the cost impact over several years.

Solution
Westin prepared a SCADA Master Plan that laid the foundation for technology, automation and system improvement projects that were required to meet the technical and business requirements of SBSA.
Westin defined a control system architecture for hardware and software as well as a project delivery method. Westin has executed this program incrementally through a series of projects and services including:

• New SCADA HMI and central data acquisition unit
• PLC control of four main pump stations
• PLC control of wastewater treatment plant unit process areas including:
  • Chlorination/dechlorination
  • Final effluent pumping
  • Dewatering systems
  • Dual media filters, feed pumps and auxiliary systems
  • Reclaimed water
• Detailed control system designs including instrumentation, electrical, control panels, PLC hardware and networks
• PLC programming, HMI software configuration, systems integration, training and start-up services
• Annual system maintenance and support

Outcome
SBSA is a progressive organization that has leveraged their SCADA strategy to:

• Improve operational efficiency and productivity through automation
• Comply with NPDES permit requirements
• Align projects and expenditures with available annual funding
• Standardize hardware and software
