SCA Water Treatment Plant Supplemental Treatment and Design Work Plan
The Sediment Containment Area (SCA) Water Treatment Plant normally discharges treated effluent to the Metropolitan Syracuse Wastewater Treatment Facility (Metro) for supplemental treatment, prior to discharge to Onondaga Lake. The design average and peak discharge flows are 6.5 and 10 million gallons per day (MGD), respectively. During wet weather events, the hydraulic capacity of the Metro facility may be reached. This periodically results in Metro being unable to receive flow from the SCA Water Treatment Plant. In order to maximize operational up-time for future dredging operations, provisions (supplemental treatment) will be made to facilitate discharge of up to 6.5 MGD of SCA Water Treatment Plant effluent to Onondaga Lake.This discharge is expected to occur only during wet weather shutdowns.
