Secondary treatment process at Lions Gate The plant will be designed for a life span of 80 years, with all the major equipment to be installed at a safe height to protect them from a 100-year sea level rise.īiogas produced by the treatment process will be recovered to generate electricity at the site, heat from the treated effluent will be supplied to a local district energy system and biosolids from the plant will be conveyed to the neighbouring areas for land reclamation and soil fertilisation. Sustainability features of the new WWTP include rain harvesting and green roof systems. Sustainability and energy efficiency features An outdoor public space will be created at the foot of Pemberton Avenue and space for community use will be provided within the building for education, outreach and public meetings. The new WWTP will integrate the surrounding community, with its main building to be located along 1st Street West to reduce the visual impact of the building and optimise the limited available space. A vegetated buffer along the north side of the plant will be created and the spaces featuring mechanical equipment will be acoustically insulated to minimise noise. Indicative designs for the Lions Gate Secondary WWTP integrate a fully enclosed two-stage odour control system and a permanent air quality monitoring station to be constructed within or near the site. The new secondary treatment plant will meet the environmental requirements set by the Canadian Council of Ministers of the Environment (CCME). The second primary treatment plant, Iona Island WWTP, is expected to be upgraded by 2030.Īll primary treatment plants in Canada are required to be upgraded to secondary treatment as per Metro Vancouver’s Integrated Liquid Waste and Resource Management Plan, approved by the BC Ministry of Environment in May 2011. The existing Lions Gate WWTP, which was opened in 1961, is one of the two remaining primary WWTPs in Vancouver. The Missouri River (WWTP) is located south of the Veterans Memorial Bridge in Omaha City. Missouri River Wastewater Treatment Plant, Omaha, US The budget for the current project is estimated at $700m.įinancing for the project will be partially provided through the Building Canada Fund, which is providing $14bn over ten years for major economic projects, including a $10bn allocation to a Provincial-Territorial fund for infrastructure projects, such as wastewater treatment. The project will be implemented through the design-build-finance (extended warranty) procurement approach, under which Metro Vancouver will maintain and operate the new plant. The new plant will be designed with an option to be expanded to include tertiary treatment in future. The detailed engineering and architectural design phase will commence in 2014, while construction is scheduled to start in 2017. In November 2013, the indicative design for the new WWTP was approved by the Metro Vancouver Board. The site, covering an area of approximately 3.5ha, is located on a former British Columbia Railway land. The new project is located approximately 2km east of the existing WWTP and Lions Gate Bridge in North Shore, Vancouver.
The Lions Gate Secondary Wastewater Treatment Plant (WWTP), which is expected to come online in December 2020, will replace the existing Lions Gate Primary WWTP. The operations and maintenance building will also provide space for community use.ĭisinfected water from Lions Gate Secondary WWTP will finally be discharged to the Burrard Inlet.
