Sewage Collection System Photo Gallery

Construction activity on the Sewage Collection System (SCS) component of the Harbour Solutions project has been underway since fall 2003. Completion is scheduled for summer/fall 2008.

The function of the SCS is to convey effluent to the three new wastewater treatment plants. The SCS is made up of all required piping, pumping stations, a 1-km tunnel under downtown Halifax, outfalls and diffusers which help to distribute/diffuse the treated water over a wider area once it is discharged into the harbour.
