Project Overview

Felix was the General Contractor (part of a Job Order Contract) on this project that involved converting old traveling bridge sand filters at the 157th Ave Wastewater Treatment Plant to Disk filters.  The scope included installation of three (3) disk filters and associated equipment, valves, instrumentation, and electrical panels in two phases to allow the plant to stay operational while demo’ing the existing traveling bridge filters and associated launders, bridge rails, leveling strips, underdrain system, media and accessories.  Concrete demo and new walls were constructed to allow the new disc filters to fit/operate in the existing footprint of the old filters.  New handrail, grating, and a shade structure were added to provide additional equipment shading.  Development of the SCADA screens was completed to monitor and control the disk filters.  All modifications were done as the plant stayed in operation and when needed bypass pumping was strategically set up to maintain plant flow requirements.
