North Shore Sanitary District, Gurnee, Illinois

2003 ACEC Wisconsin Best of State Award Winner

Donohue & Associates and the North Shore Sanitary District (NSSD) in Gurnee, Illinois received a Best of State Award in the 2003 ACEC Wisconsin Engineering Excellence competition. The award recognizes the planning and design of odor control improvements for sludge handling facilities at NSSD’s wastewater treatment facility.

The new facilities are the most advanced odor control system in the country and are achieving record levels of performance, better than any comparable system in the wastewater industry. The improvements include several innovations that resulted in the removal of high levels of complex odorous compounds. Prior to the project, NSSD was receiving numerous complaints relating to odors from the sludge handling facilities.
