Victoria, BC – The Capital Regional District (CRD) has awarded a $29-million contract to Don Mann Excavating Ltd. to construct the Residual Solids Conveyance Line (RSCL). As part of the Wastewater Treatment Project, the Residual Solids Conveyance Line will convey 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.
Don Mann Excavating is a Victoria-based civil contracting company with over 70 years’ experience specializing in excavation, road building, and installation of underground utilities.
Construction of the RSCL will begin this winter and will take approximately 18 months to complete. The RSCL will be installed in segments within existing road rights of way. It will be constructed in accordance with a traffic management plan to minimize impacts to vehicle traffic, cyclists and pedestrians, including measures to minimize work hours at the major intersections the route crosses to accommodate commuter traffic.
The RSCL includes two pipes and three small pump stations. The first pipe will be 250mm (10 inches) in diameter and 19.3km long connecting the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility. 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 at the Residuals Treatment Facility to the Marigold Pump Station, from where it will be returned to the McLoughlin Point Wastewater Treatment Plant through the existing conveyance system. The alignment was developed based on technical, environmental, social and economic considerations and included input from the municipalities of Saanich, Esquimalt and Victoria.
As part of constructing the RSCL, infrastructure improvements will be made at certain points along the route including new curbs, sidewalks and watermain upgrades.
The Wastewater Treatment Project is being funded by the Government of Canada, the Government of British Columbia and the CRD.
