Pump Stations Maintenance

Flood control is provided by a system of levees, channels and storm drains. All stormwater runoff is conveyed by gravity through a system of drainage lines and canals into the suction bays of various pump stations then pumped to a higher elevation into larger levees or the ocean. The pump station operators are responsible for the operation and maintenance of 8 pump stations, 4 dams, 5 urban run-off diversions, containing 46 pumps  throughout the Orange County watershed area. The primary goal of the group is to provide staffing for operations and maintenance of all pumping equipment and associated machinery.
 
All pumping equipment is driven by either natural gas combustion engines with propane back-up or electric motor drives. Some pump stations are now monitored using SCADA, which stands for Supervisory Control and Data Acquisition. SCADA systems interface with District computers to alert staff of operational problems. The technology saves time money by pinpointing malfunctions and minimizing staff time to shut off general alarms for non-critical situations.
