The Capital Regional District (CRD) on Vancouver Island 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 (awarded to Victoria-based Don Mann Excavating in Nov. 2018/Parsons is the design consultant) for the District’s Wastewater Treatment Project.
Knappett is a Victoria-based general contractor with over 35 years of experience working on institutional, commercial, civil and industrial projects.
Construction of the pump stations is anticipated to begin in May and take approximately 14 months to complete. The 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.
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 and 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.
