Description
The Residual Solids Conveyance Line is part of the Wastewater Treatment Project. It includes two pipes along with three pumping stations. The two pipes will connect the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility at Hartland Landfill and will be installed in a common trench where possible.
Don Mann Excavating was selected by the Capital Regional District through a competitive selection process to build the Residual Solids Conveyance Line. Construction activities began in is expected to take approximately 18 months to complete.
Current Construction Activities
Pipe installation began in February 2019 with multiple crews working along the alignment.
Section 1: Wollaston Street and Newbury Street
Section 2: No current pipe installation
Section 3: Interurban at Camosun College
Section 4: Willis Point Drive
Background
The first pipe will be 250mm (10 inches) in diameter and 19.3km long, and will transport residual solids from the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility for treatment. The second pipe will be 300mm (12 inches) in diameter and 12.4km long, and will return the liquid removed from the residual solids during the treatment process to the Marigold Pump Station, from where it will be returned to the McLoughlin Point Wastewater Treatment Plant through the existing conveyance system. The Wastewater Treatment Project team has worked with the municipalities of Saanich, Esquimalt, and Victoria on the alignment of the Residual Solids Conveyance Line.
As requested by the District of Saanich, infrastructure improvements during construction will be completed. This includes traffic calming measures and pedestrian connectivity through a new traffic circle at Vincent Avenue/Bodega Road, and a new concrete curb, gutter and sidewalk on Esson Road.

Following a competitive process, the Wastewater Treatment Project Team has awarded a contract for the construction of the pipes to Don Mann Excavating Ltd. The team is partway through a competitive selection process for the construction of the pump stations, and has issued a Request for Proposals (RFP) to three qualified proponents as part of the competitive selection process for the contract to build the pump stations.
