BACKGROUND
The Orange County Sanitation District (OC San) operates 15 pump stations as part of its collection system. These pump stations require emergency power during the loss of utility power. Seven of the pump stations include dedicated, on-site standby generators. The remaining eight pump stations have connectors to quickly connect a portable generator.
Pump stations typically have a main switchboard to distribute power, either from Southern California Edison or standby generator, through motor control centers to all the loads in the pump station. These switchboards require periodic inspection and maintenance that requires them to be de-energized.
RELEVANT STANDARDS
• Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
• Commitment to safety & reducing risk in all operations
PROBLEM
The current configuration of the Southern California Edison and emergency generator power feeds through the main switchboard do not allow for pump station operation during switchboard inspection and maintenance. The main switchboard must be fully de-energized to perform the required inspection and maintenance.
The current maintenance practice is to by-pass a pump station or do the work at night during low flow periods while carefully monitoring wet well levels and certain low-lying upstream manholes to be sure that no spill occurs. If the level does rise too quickly, the work must be immediately stopped to put the pump station back in service.
PROPOSED SOLUTION
Award a Construction Contract for Pump Station Portable Generator Connectors, Project No. FE19-01 to reconfigure the generator connections to allow pump station operation and switchboard maintenance at the same time. This project will install new generator connectors at 13 of the 15 pump stations. An earlier project installed a portable generator connector at one of the pump stations which is operating satisfactorily, and the other pump station is planned for demolition in the near future.
TIMING CONCERNS
Until these generator connectors are installed, routine switchboard maintenance runs the risk of creating a sewage spill.
RAMIFICATIONS OF NOT TAKING ACTION
Routine maintenance on the main switchboard will continue to be more difficult to perform during the limited low flow windows or with costly by-pass pumping.
