Jeff Martin has over 25 years of experience in planning, design, project management, strategic planning, and business management in the areas of computer systems, instrumentation, process automation for water, wastewater, industrial, aquaculture, mining and military systems. 2

3 Presentation Outline Challenges/Concerns of a typical SCADA Control System Case Study Polk County Utilities SCADA Master Framework Summary 3

4 Challenges/Concerns of a typical SCADA Control System Management: Difficulties in making key decisions due to unavailability of big picture data Engineering: Dealing with inconsistencies in control system architecture; Non-isolation of process networks and other networks Operations and Maintenance: No remote access to all process data IT: Cyber Threats 4

5 Challenges/Concerns of a typical SCADA Control System 5

6 Case Study Polk County Utilities Total Area: 2011 sq mi; Population: 623,009 6

7 Case Study Polk County Utilities Facilities 3 regional WWTFs and 4 packaged WWTFs 37 WPFs Over 300 Lift Stations Central Monitoring Facility Other Facilities such as Well sites, Booster Stations, Meter Stations, Reclaim Water Store/Re-pump facilities and Facility interconnects Communication between different facilities Different technologies/frequencies using Wireless Radio and Auto dialer for alarms 7

8 Case Study Polk County Utilities Challenges: Varying Network Architectures Mix of SCADA and IT networks Different Hardware and Software platforms Disparate communications to facilities Non-availability of centralized management Non-availability of remote access to process data and other software applications Non-availability of communication to certain facilities 8

9 Case Study Polk County Utilities Approach to SCADA Master Framework Conducted a kick off meeting with PCU s Senior Management and Engineering Staff Identified Critical Success Factors for PCU. The top 3 factors were: Data Access Reliability Overall with a solid foundation Came up with a step-by-step approach for PCU s SCADA Master effort 9

11 SCADA Master Framework Needs Analysis and Problem Identification Communications, Operator Access and Security SCADA Architecture Standards SCADA Master Report 11

12 SCADA Master Framework 12

13 SCADA Master Framework 13

14 SCADA Master Framework Results of this approach: Development of the following based on the needs of the operational group (Management, Engineers, IT, Operators and Maintenance Staff): Centralized system allowing for remote data access Reliable Communication methods Ideal SCADA architectures for consistency Hardware and Software Standards The workshop/survey results exactly matched the top 3 critical success factors identified by PCU s Senior level staff 14
