Upgrading to Tertiary Treatment
In the interest of better protecting the environment, we have updated the design of the new North Shore Wastewater Treatment Plant so that it will provide tertiary treatment instead of secondary treatment. Adding tertiary treatment, a filtration system that removes additional substances from the treated wastewater, ensures that the treated wastewater released into the marine environment is much cleaner. This level of treatment will exceed federal regulatory requirements for treatment technology.
The upgrade to tertiary treatment reflects the input Metro Vancouver received from key stakeholder groups and participating First Nations. It also reflects our commitment to protect the environment and strengthen the quality of life in our region for current and future residents.
The treatment plant is now anticipated to be complete and fully operational in 2024. As this project has progressed, we have embraced significant opportunities for our region, including the update to the plant from secondary to tertiary treatment. We have also experienced many challenges, such as difficult ground conditions, seismic resilience requirements, space constraints, geotechnical complications, contractual issues, and COVID-19 – all of which contributed to delays in construction.
