Pump Station Management

• JEA operates and maintains gt1,100 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.

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.

Advantages During Power Outages

• 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 (SSOs) 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 JEAs 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 SSOs were prevented.

14
Lessons Learned

• Sharing available assets between JEAs 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 anothers
  problems that they may have a possible solution
  to.
