The Village of Cary, Illinois, Wastewater Treatment Plant (WWTP) Phase I Improvements project was selected for a Project of the Year Award through the Chicago Metro Chapter–Fox Valley Branch of the American Public Works Association; the award was presented on January 14 in Aurora, Illinois. The Village operates a WWTP that discharges into the Fox River. The Illinois Environmental Protection Agency listed the Fox River as impaired for water quality parameters. The Village engaged us for the Phase I WWTP Improvements project, with the primary goal to meet current and foreseeable regulatory requirements. The project included converting a portion of the activated sludge system to biological phosphorus removal – within the existing aeration tanks – with chemical phosphorus removal backup. It also included replacing existing chlorination facilities with an ultraviolet disinfection system, adding a new digester mixing system for the primary anaerobic digester, incorporating various energy efficiency improvements, and integrating supervisory and data acquisition system improvements.
