2015 ISA WWAC SymposiumAug 4-6, 2015 – Orlando, Florida, USA 4
Challenges/Concerns of a typicalSCADA Control System
• Management: Difficulties in making key decisions due tounavailability of big picture data
• Engineering: Dealing with inconsistencies in controlsystem architecture; Non-isolation of process networksand other networks
• Operations and Maintenance: No remote access to allprocess data
• IT: Cyber Threats

• Total Area: 2011 sq mi; Population: 623,009
2015 ISA WWAC SymposiumAug 4-6, 2015 – Orlando, Florida, USA 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, MeterStations, Reclaim Water Store/Re-pump facilities and Facilityinterconnects
• Communication between different facilities– Different technologies/frequencies using Wireless Radio and
Auto dialer for alarms
2015 ISA WWAC SymposiumAug 4-6, 2015 – Orlando, Florida, USA 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 othersoftware applications
– Non-availability of communication to certain facilities
2015 ISA WWAC SymposiumAug 4-6, 2015 – Orlando, Florida, USA
• Approach to SCADA Master Plan Framework
– Conducted a kick off meeting with PCU’s Senior Managementand Engineering Staff
– Identified Critical Success Factors for PCU. The top 3 factorswere:
Data Access
Reliability
Overall Plan with a solid foundation
– Came up with a step-by-step approach for PCU’s SCADA MasterPlan effort

SCADA Master Plan Framework
• Results of this approach:– Development of the following based on the needs of the
operational group (Management, Engineers, IT, Operators andMaintenance 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 3critical success factors identified by PCU’s Senior level staff

SCADA Master Plan Framework
• Ok, so how should you implement these upgrades?– Identify Priorities
– Coordinate with other Master Plans/Goals
– Calculate estimated Cost of each upgrade
– Allocate the cost to the correct budget type
– Identify in-house upgrades and upgrades requiring externalassistance

Summary
Key points of this presentation:
•Obtain common groundsbetween your operational groups
•Identify the best communicationand network architecture
•Defining Hardware and Softwarestandards becomes easy at thisstep
•Identify the upgrades andprioritize based on criticality anditems that currently requires themost maintenance
•Come up with a plan toperiodically review and updateyour standards document
