The East Orange Water Commission retained our firm to design the installation of an emergency power system to provide back-up power for the entire White Oak Ridge Pumping Station. New equipment included a 2MW – 5kV outdoor diesel genset in a sound attenuated enclosure with in-base fuel tank & fuel transfer system from an aboveground fuel tank; 5kV automatic transfer switchgear; 1000kW, 5kV load bank; 2500kVA, 34.5kV:4160kV substation transformer and related switchgear. This project involved all aspects of building construction and design disciplines. Challenges included planning and implementing the work to tie in the new equipment while maintaining operations.
