Effective Utility Management
• Pressure to do more with less resources• Aging Facility Automation systems• Increasingly stringent regulatory requirements• Rising labor and components costs• Rapidly changing workforce
• Legacy SCADA systems reaching the end of their shelf life
• Most Utilities try to turn from one urgent priority to another
Utility SCADA Bottom Line
• Need accurate field information in order to plan
• Need methods to access information regarding asset inventory and energy consumption
• Need to be able trust and depend on the field information
Utility Managers and SCADA
RAMS – Reliability, Accessibility, Maintainability, Security (asset, SCADA and network)Connectivity to UMS (Auto. Reporting, CMMS)Systems standardization (Efficient O&M)Process optimization (for cost saving - labor, power and chemicals use) Systems upgrade to comply with growth needs Remote access (via secure connection)

Benefits to Utility
• Increased Operational Efficiency• Lower Operating Costs• Document Regulatory
Compliance• Systems Upgrades and
replacements are planned and financially based on CIP and not O&M expenditure
• Framework for educated decision making process
Questions for the Utility
Are you getting value out from your automation and SCADA investments?
Are your facilities operating at peak efficiency? Are you able to automatically generate
Regulatory and internal reports & trends based on laboratory, control/SCADA system, & operator data?
Do you trust your data collection methods and communication systems?
Do you have a plan for automating the monitoring & control of your operations?
Do you have a SCADA Master Plan in place?
Garland Duck Creek WWTC
The Duck Creek Wastewater Treatment Center (WWTC) began operation as a trickling filter/solids contact (TF/SC) plant in 1986, with a permitted capacity of 30 mgd.
The plant was evaluated in 2001-2002 and a need was identified to expand the capacity to provide for future growth and planned diversion of flow from the Rowlett Creek WWTC.
Garland Duck Creek WWTC
The project to expand the plant from a nominal treatment capacity of 20 mgd to a capacity of 40 mgd was initiated in 2002.
The expansion, completed in 2006, provides a new stand-alone activated sludge system that has the capacity to treat 50-percent of the 40 mgd design flow, with the TF/SC system treating the remaining 50-percent.
Garland Duck Creek WWTC
Since the client was familiar with Control Microsystems controllers, nine new Control Microsystems SCADA Pack 32 controllers were added, seven new SCADA Pack controllers were added, and the existing SCADA Pack controllers were relocated to the filters.
Garland Duck Creek WWTC
Redundant Wonderware servers were added along with three operator workstations. A Historian with reporting capability was added. The system was originally designed to monitor plant operations only. However, we were able to provide remote control as well.
Garland Duck Creek WWTC
Data from packaged control systems was also brought into the HMI to allow remote monitoring for systems such as the diesel engine generators and the aeration blowers.
Garland Duck Creek WWTC
Misc. instruments were added throughout the plant:• 12 Hach LDO probes in the new aeration basins• Flowmeters on sludge piping throughout the facility• Pressure and level devices throughout the plant.

Next Step:Assisting the Client with Maintenance support to include: Phone Support On site Support Systems’ Yearly Maintenance Support
Example: City of Rio Rancho, NM
Objectives: • Assess the existing
SCADA and Telemetry systems
• Identify SCADA and Communication System needs
• Formulate a practical and cost-effective implementation
Recommendations: • Formulate SCADA system standards: develop
standards for the SCADA system and the PLCs• Relocate central operations to a newer site• Develop Network Master Plan: to improve SCADA
system security & to establish comm. standards
CoRR, NM SCADA Master Plan
• SCADA Master Plan included:• Assess the existing conditions• Define the client’s requirements• Study and compare the applicable
technologies and options • Interview / work with Vendors• Perform pilot tests
• Perform Cost Analysis of various options
• Produce a phased, sequenced road map to deliver final SCADA system

Road Map / Master Plan
CoRR, NM SCADA Master Plan
• Study included:• Communications between treatment plants
and all conveyance points (lift stations etc)• Radio path studies between sites• Methods for data reporting for compliance• Methods for saving and accessing data
across the entire Utility• Methodology for verifying and collecting
field and manually entered data• Accuracy of primary field instruments• Communication protocols between
processors and remote sites• Tie in with CMMS, LIMS and other systems
