Harbor Brook Constructed Wetlands Pilot Treatment System

The Harbor Brook CSO 018 Constructed Wetlands Pilot Project serves the dual purposes of treating overflows from CSO 018, currently discharged into Harbor Brook, while also acting as a demonstration project to test the effectiveness of three types of constructed wetland treatment systems (floating wetland island, vertical down flow, and surface water treatment wetlands). The project is located within the approximately 34 contiguous acres of Onondaga County-owned land known as the Velasko Road Detention Basin. This constructed wetland pilot project captures and treats approximately 14.8 million gallons of combined sewage each year and substantially improves the quality of the stormwater discharge into Harbor Brook.
