The Residual Solids Conveyance Line is part of the Wastewater Treatment Project. It includes two pipes along with three small pump 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.
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.
As requested by the District of Saanich, infrastructure improvements including a new traffic circle at Vincent Avenue/Bodega Road, and a new concrete curb, gutter and sidewalk on Esson Road will be completed during construction.
Construction of the RSCL began in February 2019 and is expected to be complete in spring 2020. There are multiple crews working along the alignment.
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:
- Interurban Road and Courtland Avenue
- Interurban Rail Trail near West Saanich Road and Observatory Road
- Willis Point Road within the footprint of the Hartland Landfill
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 began in May 2019 and will take approximately 14 months to complete. Construction is underway at all three pump stations.
