Construction Impacts

Most of the construction will take place within existing boundaries of the plant. However, a new outfall will be built from the plant to the river by tunneling. Activities associated with this work include:

  • Building demolition
  • Delivering, excavating and removing soils and other materials
  • Tunnel shaft excavation
  • Shaft and diffuser construction from barges in river

Work Hours

Most of the work will occur during the City of Delta’s regular construction hours:

  • Monday to Friday: between 7:00 am and 7:00 pm
  • Saturdays: between 9:00 am to 5:00 pm

Beginning in June 2020, certain construction activities that will not have a significant impact on the surrounding communities will take place 24 hours a day, 7 days a week. Please note that river conditions and flow rates may impact the work schedule. All work will comply with the City of Delta and Vancouver Fraser Port Authority’s granted bylaw variance.


All work will comply with the City of Delta’s noise bylaws or granted variances. Where practical, crews will attempt to reduce noise impacts. Generators may be required to run overnight. Diesel impact pile driving will be done only during the City of Delta’s regular construction hours.


Access to all businesses will be maintained. Construction of the diffuser system and riser shaft will take place outside of the river navigation channel to avoid impacts to river users.

Traffic Impacts

During construction additional truck traffic will be present on surrounding roads as materials are removed and delivered to the work site.
