Lions Gate Secondary Wastewater Treatment Plant

Description:As identified in Metro Vancouver's Integrated Liquid Waste and Resource Management Plan, the existing Lions Gate Primary Wastewater Treatment Plant, servicing the North Shore Communities of Metro Vancouver, will be replaced by a new secondary wastewater treatment plant by 2020. In upgrading the Lions Gate plant, Metro Vancouver embarked on an Integrative Design Process (IDP) that is proving to realize this project's potential to demonstrate Metro Vancouver's commitment to sustainability, provide leadership, and build a model wastewater treatment facility, while fulfilling its mandate of provision of a core service. On November 15, 2013, the Metro Vancouver Board unanimously endorsed the Indicative Design for the new Lions Gate Secondary Wastewater Treatment Plant. The Indicative Design will be used as the basis for pursuing Senior Government Funding and the design and construction phase. The Indicative Design is the key outcome of the Project Definition Phase completed by Metro Vancouver. Grounded in the key project objectives, the Project Definition Phase has been guided by the IDP that brought together technical experts, community interests, and decision makers which expanded the potential of the Lions Gate Secondary Treatment Plant. The indicative design considered many issues including visual aesthetics, odour control, truck traffic, noise, resiliency to sea-level rise and future adaptability, and costs to taxpayers. The configuration of the new plant is a compact and contextual addition to the diverse zoning in the neighbourhood. At a recent public meeting, 80% of the respondents felt that the plant design met the values of the community. Some of the design features include a translucent gallery to reduce the apparent height of the building from street level, extensive planting along the front facade, and a pedestrian scaled public entrance and outdoor open space. Odour control applies the principles of prevention by minimizing the release of odours, containment by physical covers, treatment by equipping with a two-stage odour treatment system, and dispersion by discharging treated air through a stack. The presentation will provide an overview of the Indicative Design of the new facility. It will describe the recommended treatment technology, architectural character, and community integration opportunities and lay out the next steps in Metro Vancouver's approach for this new integrated facility.
