Description

The Residual Solids Conveyance Line is part of the Wastewater Treatment Project. It includes two pipes along with four pumping stations. The two pipes will connect the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility at Hartland Landfill and will be installed in a common trench where possible.

Don Mann Excavating was selected by the Capital Regional District through a competitive selection process to build the Residual Solids Conveyance Line. It is anticipated that construction will begin in Winter 2018, and is expected to take approximately 18 months to complete.

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.The Wastewater Treatment Project team has worked with the municipalities of Saanich, Esquimalt, and Victoria on the alignment of the Residual Solids Conveyance Line.

As requested by the District of Saanich, infrastructure improvements during construction will be completed. This includes traffic calming measures and pedestrian connectivity through a new traffic circle at Vincent Avenue/Bodega Road, a new concrete curb, gutter and sidewalk on Esson Road and on Grange Road.

Procurement

Following a competitive process, the Wastewater Treatment Project Team has awarded a contract for the construction of the pipes to Don Mann Excavating Ltd. The team is partway through a competitive selection process for the construction of the pump stations, and has issued a Request for Proposals (RFP) to three qualified proponents as part of the competitive selection process for the contract to build the pump stations.

Five submissions were received in response to the Request for Qualifications (RFQ) which closed September 11, 2018. The following teams have been selected to participate in the RFP stage:

• Bennett Mechanical Installations (2001) Ltd.
• Graham Infrastructure LP
• Knappett Projects Inc.

Proponents are scheduled to submit their proposals in December 2018 and the Wastewater Treatment Project Team expects to award a contract in winter 2018-19.

Community Engagement

The Project Team will hold two community information open houses prior to construction beginning on the Residual Solids Conveyance Line to provide information on construction timing and impacts.
