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.
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 spring 2019 and 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: Hereward Road; Ker Avenue; Selkirk Avenue
Section 2: No current pipe installation
Section 3: Interurban at Viaduct Ave
Section 4: Wallace 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.
Pump Stations
Knappett Projects Inc. was selected by the Capital Regional District through a competitive selection process to build three small pump stations along the Residual Solids Conveyance Line. Pump stations are used to move wastewater from a lower elevation to a higher elevation. They are being built within the road right-of-way and will be located at:
- 4298 Interurban Road (Courtland Ave and Interurban Road)
- 5062 West Saanich Road (near West Saanich Road and Observatory Road)
- 280 Willis Point Road
The pump stations are designed with state-of-the-art odour control systems that contain and suppress odour so there is no discernible smell in the community. Operating noise will be minimal and comply with District of Saanich standard practice. Landscaping features include a variety of trees, shrubs and ground coverings that will be planted and maintained.
Construction activities are anticipated to begin in May 2019 and take approximately 14 months to complete.
Community Engagement
The Project Team held two community information open houses in November 2017 and two more at the end of November 2018 prior to construction beginning on the Residual Solids Conveyance Line to provide information on construction timing and impacts.
