Wet Side Redundant Power Improvements

This project included the installation and testing of two 2000 kW diesel standby power generators, two 4000-gallon subbase fuel tanks, 1 MW load bank, cable tray installation and structural modifications to existing facilities. Transfer of responsibility for the generators was required between the manufacturer and the installation contractor. A rigorous pre-offloading inspection was specified for the generators and installation required modifications that included demolition and removal of a steel fixed film reactor (FFR) exoskeletal structure.

The generators were set and assembled on a concrete pad within the FFR footprint on top of existing stem walls and connected to a 480V switchgear which required routing of two 130-foot runs of 24-inch wide cable tray through congested treatment plant galleries. Connection and startup of the generators involved full shutdowns of the switchgear which supplied power to active plant equipment. Startup included close coordination with facility staff to demonstrate that all equipment would perform as expected in the event of a power outage.
