Description

Residual solids from the McLoughlin Point Wastewater Treatment Plant will be piped through the Residual Solids Conveyance Line to the Residuals Treatment Facility at Hartland Landfill, where they will be turned into what are known as “Class A” biosolids. These biosolids are a high quality by-product treated such that they are safe for further use.

The Residual Solids Conveyance Line includes two pipes along with four or five pumping stations. The two pipes will be installed in a common trench where possible and will connect the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility at Hartland Landfill. The first pipe will be 200mm in diameter, 18.5km long, and will transport residual solids from the McLoughlin Point Wastewater Treatment Plant to the Residuals Treatment Facility. The second pipe will be 350mm in diameter, 11.5km 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 collection system.

The Wastewater Treatment Project Team is currently working with the municipalities of Saanich, Esquimalt, and Victoria on the route of the Residual Solids Conveyance Line. Preliminary geophysical and geotechnical work will provide additional information about the subsurface conditions along the proposed route. This information will assist in developing the indicative design and alignment of the Residual Solids Conveyance Line.

Construction of the Residual Solids Conveyance Line is anticipated to begin in the second quarter of 2018.

Community Engagement

The Wastewater Treatment Project Team is currently establishing a process for communications and engagement in Saanich that will include working with community associations and/or the Saanich Community Association Network.

Before and during the construction phase of the Residual Solids Conveyance Line the Project Team will engage with nearby communities as we plan communications activities and develop plans to mitigate construction impacts. The team will also provide information about communications tools and seek feedback about the most effective ways to communicate with impacted communities during construction.

The Project Team anticipates holding information meetings in Saanich in the fall of this year. The Project Team plans to coordinate these meetings with staff from the District of Saanich and members of the Saanich Community Advisory Network, as well as, Willis Point, Todd Creek and Peninsula Streams. The purpose of these meetings will be to share the indicative design for the Residual Solids Conveyance Line alignment (including the anticipated location of the pump stations) and to seek public input that could be considered, along with technical and financial considerations, in finalizing the design.
