Outfall Construction

Construction of the CWWTP outfall began Monday, November 23, 2020 with the arrival of the first of seven truckloads of pipe.

The timeline for the outfall construction is currently scheduled between December 1, 2020 and February 15, 2021, which is the Department of Fisheries and Ocean prescribed winter timing window of least risk for in-water construction activities, provided that environmental monitoring and proposed environmental mitigation measures are being followed to ensure compliance with the Fisheries Act and Marine Mammal Regulations.

The outfall will discharge treated effluent into the Salish Sea. We will be treating and disinfecting 100 per cent of the effluent prior to discharging to the outfall once the facility is completed as per provincial and federal regulations.

The pipeline will extend about 700 metres offshore, with approximately 650 metres suspended above the ocean floor on concrete ballast blocks, and 50 metres of pipe will be buried in the inter-tidal zone. There will be approximately 100 metres of outfall that the future CWWTP will connect to. Temporary bypasses connecting the existing Townsite Treatment Plant outfall pipes to the new CWWTP outfall are currently proposed by the contractor.

The outfall construction contract was executed by the contractor, Caribou Mountain Construction (CMC) on Thursday, November 26, 2020, and Notice to Proceed was issued from Associated Engineering (AE) to CMC on Friday, November 27, 2020 following contract execution by the City of Powell River.

Caribou Mountain Construction of Alberta, a 100 per cent owned First Nation company, is the outfall contractor and has begun the mobilization of crew and equipment to the laydown area adjacent to the site.
