12 Avenue Pump Station Replacement

Stone column installation works are underway to improve existing ground conditions. To facilitate these works, the temporary park trail along the pump station construction site will be closed from February 18 to March 6, 2020 during construction hours. Thank you for your patience.


12 Avenue Pump Station Replacement Project


The Boundary Bay Stormwater Management Improvements Project will improve drainage and reduce flooding in the agricultural area of Tsawwassen. Phase 1 began in April 2018 and consisted of new storm sewer main along Boundary Bay Road and a flow control structure near Ironwood Place. Phase 2 is underway and involves the installation of a new pump station.

The existing 12 Avenue Pump Station is in excess of 50 years old and requires replacement. The pump station provides drainage for a large portion of Tsawwassen, encompassing approximately 900 hectares. The proposed works consist of the following components:

  • Decommissioning and removal of the existing pump station; 
  • Seismic ground improvements; 
  • Construction of a new pump station; 
  • New stormwater intake structure; 
  • New stormwater outlet structure with a viewing deck; and 
  • Raising of the dike along the frontage of the new pump station.

Construction impacts to traffic on Boundary Bay Road and 12 Avenue are anticipated to be minimal. Traffic Control shall be present on site to allow construction vehicles access to the project site.

Access to Boundary Bay Regional Park & Dike

To safely complete the works, a portion of the dike will be closed to the public and the parking lot at 12 Avenue and Boundary Bay Road will be used by the contractor as a staging area. A detour route, found here, along Boundary Bay Road and Boundary Bay Regional Park will be established to connect pedestrians and cyclists to the dike trail.

Project Timeline

Construction is scheduled to begin in September 2019, with an anticipated completion date of fall 2020.
