9 Utility Managers and SCADA

10 Utility Managers and SCADA

11 Effective Utility Management May 2007: 6 major water and wastewater associations and EPA signed an agreement to support Effective Utility Management AWWA WEF AWCWA NAWC APWA AMWA Result: Primer for Water and Wastewater Utilities: Ten Attributes of Effectively Managed Water Sector Utilities

12 Ten Attributes of Effectively Managed Water / Wastewater Sector Utilities Source: Effective Utility Management, A Primer for Water and Wastewater Utilities, June 2008

13 How a SCADA System Fits In Planning and long-term Monitoring Up to date information on the quality of W/WW Information to make uniformed decisions Real-time Monitoring for fast responses Tie into CMMS Fine tuning processes Maximizing energy and chemical usage

14 How a SCADA System Fits In Asset Management Analysis Capital Asset Management GIS Geographical Information System Reports and Financial Statements ERP Enterprise Resource Planning CMMS Computerized Maintenance Management System SCADA Supervisory Control and Data Acquisition Usage Information Analytical Equipment Results LIMS Laboratory Information Management System Customer Services

15 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

16 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

17 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)

24 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

25 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?

26 Garland Duck Creek WWTC

27 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 and a need was identified to expand the capacity to provide for future growth and planned diversion of flow from the Rowlett Creek WWTC.

28 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 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.

30 Garland P&ID Detail

31 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.

32 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.

33 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.

34 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.

35 Garland SCADA Maint. support Next Step: Assisting the Client with Maintenance support to include: Phone Support On site Support Systems Yearly Maintenance Support

36 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

37 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 Assess Define Study Cost Road Map / Master Plan

38 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
