Description

The Residual Solids Conveyance Line (RSCL) is part of the Wastewater Treatment Project. It includes two pipes along with three small pump stations. The two pipes connect the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility at Hartland Landfill.

The first pipe is 250mm (10 inches) in diameter and 19.3km long, and transports residual solids from the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility for treatment. The second pipe is 300mm (12 inches) in diameter and 12.4km long, and returns the liquid removed from the residual solids during the treatment process to the Marigold Pump Station. From there it is returned to the McLoughlin Point Wastewater Treatment Plant through the existing conveyance system.

Construction of the RSCL began in February 2019 and was completed in summer 2020.

Pump Stations

Knappett Projects Inc. was selected by the CRD 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 within the road right-of-way and are 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, once the commissioning phase is complete, there is no discernible odour 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 majority of construction is complete at all three pump stations. The work to get the odour control systems up to full service, as well as final cleanup, and landscaping will be complete in spring 2021.
