The West Branch Combined Sewer Overflow Operations Building New Westminster, BC
The primary goal of the facility is to protect the Fraser River from untreated wastewater overflows during sustained heavy rainfall, by detaining excess combined waste and storm water before releasing it in to the Annacis Island Wastewater Treatment Plant.
In order to minimize its environmental impact, the CSO building relies heavily on materials reclaimed from a local deconstructed sawmill. A minimal amount of matching new material was added only where necessary.
The heavy timber frame reflects the industrial heritage of the area and connects the building to the design of the surrounding park, a former brownfield site.
The mixture of materials, textures and building forms helps mitigate the imposition of a large operating municipal facility on the public outdoor space. As well, the warmth and scale of wood encourages the use of the park as well as informing the public about the facility’s environmental objectives.
Wood Materials used in the project are:
- Reclaimed heavy timber Douglas fir posts and beams
- Reclaimed timber used to fabricate roof trusses
- Reclaimed glulam beams
- T&G Douglas fir horizontal siding (25% reclaimed)
- T&G Douglas fir roof decking (80% reclaimed)
- Re-sawn fir veneer plywood with cedar battens
- Framed wood stud infill walls
