The Capital Regional District (CRD), based in Victoria, has awarded a $15.9-million contract to Knappett Projects Inc. to construct three pump stations and bridge crossings along the Residual Solids Conveyance Line for its Wastewater Treatment Project.
Construction of the pump stations is anticipated to begin in May 2019 and take approximately 14 months to complete. 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 (Courtland Ave and Interurban Road)
- West Saanich Road (near West Saanich Road and Observatory Road)
- 280 Willis Point Road
The pump stations will be equipped with state-of-the-art odour control systems that contain and suppress odour so there will be 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.
The Residual Solids Conveyance Line consists of two pipes and three small pump stations. It will convey the residual solids from the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility at Hartland Landfill where they will be treated and processed into Class A biosolids. The second pipe will return the liquid removed 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. Installation of the pipes began in February 2019 and will take approximately 18 months to complete.
The Wastewater Treatment Project will provide tertiary treatment for wastewater from the core area municipalities of Victoria, Esquimalt, Saanich, Oak Bay, View Royal, Langford, Colwood, and the Esquimalt and Songhees Nations. The project consists of the McLoughlin Point Wastewater Treatment Plant and the Residuals Treatment Facility at Hartland Landfill. It also includes the conveyance system that will carry wastewater from across the core area to the McLoughlin Point Wastewater Treatment Plant and residual solids to the Residuals Treatment Facility.
