Utilizing Electric Utility Component in Asset Management of Pump Stations Overview Pump Station Management Pump Station Management Application of Electrical Assets into Pump Station Management Application of Electrical Assets into Pump Station Management Advantages in Action: September 2004 Advantages in Action: September 2004 Lessons Learned Lessons Learned

4. Pump Station Management JEA operates and maintains >1,100 Pump Stations. JEA operates and maintains >1,100 Pump Stations. Almost all (~90%) are on a Sequencing Control and Data Acquisition (SCADA) system. Almost all (~90%) are on a Sequencing Control and Data Acquisition (SCADA) system. Real time and recorded data of parameters such as well level and pump status are available for observation continuously.

9. Implementation of Electric Utility Assets into Pump Station Management Approximately 4 years ago, an effort was made to track SCADA pump stations by electric circuit. Approximately 4 years ago, an effort was made to track SCADA pump stations by electric circuit. All SCADA pump stations can now be viewed under their respective circuit with a real time account of the status of the circuit.

11. Advantages During Power Outages Real time communication allows for immediate assessment of pump station status. Real time communication allows for immediate assessment of pump station status. Allows operation and maintenance personnel to efficiently deploy mechanics and prioritize critical problems accordingly. Allows operation and maintenance personnel to efficiently deploy mechanics and prioritize critical problems accordingly. Prevents Sanitary Sewer Overflows (SSO’s) which, in turn, saves on incident response, remediation, and regulatory enforcement.

12. Advantages in Action Asset Management undertakings proved to be vital in September 2004 during Hurricanes Charley and Jeanne, which impacted Jacksonville greatly.

13. Advantages in Action (cont.) Storms caused extended periods without power in many areas of JEA’s service area. Storms caused extended periods without power in many areas of JEA’s service area. Because of Pump Station / Circuit Tracking, collection system personnel were able to prioritize which circuits needed restoration immediately based on pump station status. Because of Pump Station / Circuit Tracking, collection system personnel were able to prioritize which circuits needed restoration immediately based on pump station status. This allowed for the most efficient use of generators. This allowed for the most efficient use of generators. Numerous SSO’s were prevented. Numerous SSO’s were prevented.

14. Lessons Learned Sharing available assets between JEA’s different sectors (water, wastewater, electricity) can lead to a greatly improved process. Sharing available assets between JEA’s different sectors (water, wastewater, electricity) can lead to a greatly improved process. In this case, pump station management was enhanced as a result of resources from the electrical side. In this case, pump station management was enhanced as a result of resources from the electrical side. Communication between sectors is essential since it familiarizes one section with another’s problems that they may have a possible solution to.
