  1. Utility Asset Management Application on Pump Stations Jens Sapin, P.E. Environmental Services - Facility Compliance and Incident Response Utility Asset Management Working Session Washington, D.C. May 5, 2005

  2. JEA at a Glance Customer Accounts: • 365,000 Electric Accounts • 260,000 Water Accounts • 200,000 Wastewater Accounts Service Area: • Duval, Nassau, and St. Johns County and a small portion of Clay County. Facilities: • 5 Regional WWTP’s • 12 Satellite WWTP’s • 43 WTP’s • > 1,100 Pump Stations

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

  4. JEA operates and maintains >1,100 Pump Stations. 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. Pump Station Management

  5. Pump Run Time Maintenance

  6. Schematic Overview of SCADA System

  7. Screen Shot of Station Status

  8. Another Screen Shot of Station Status

  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. • All SCADA pump stations can now be viewed under their respective circuit with a real time account of the status of the circuit.

  10. Screen Shot of Pump Station/Circuit Status

  11. 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. Prevents Sanitary Sewer Overflows (SSO’s) which, in turn, saves on incident response, remediation, and regulatory enforcement. Advantages During Power Outages

  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. • 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. • 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. • 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.
