Overview of Projects


A new pump station and new pipes are being built as part of the North Shore Wastewater Treatment Plant. The new pump station and pipes are needed to move wastewater from the existing Lions Gate Wastewater Treatment Plant to the new Plant, and to move treated wastewater from the new plant to the existing outfall pipe.

The new First Narrows Pump Station will be located near the existing Lions Gate Wastewater Treatment Plant. The pipe alignment will extend from the existing outfall under the Lions Gate Bridge to the new North Shore Wastewater Treatment Plant. This project includes:

    • Constructing a new pump station located at the south end of Bridge Road underneath the Lions Gate Bridge
    • Installing a 1,200 mm influent sewer pipe extending from the existing Lions Gate Wastewater Treatment Plant to the new pump station
    • Installing a 900 mm forcemain extending from the new pump station to the new North Shore Wastewater Treatment Plant
    • Installing a 2,100 mm effluent sewer pipe extending from the new North Shore Wastewater Treatment Plant to the existing outfall
    • Design and construction will be done by North Shore Conveyance Partners (contract awarded in July 2018).

With plant construction underway, the Conveyance Project represents the next step in the overall North Shore Wastewater Treatment Plant program. The final step, decommissioning the existing Lions Gate Wastewater Treatment Plant, will begin in the mid-2020s and the land will be returned to Squamish Nation.

Project Activities


  • Pipe Alignment

    Installation of Outfall Pipe: March 2019 – September 2021

    The project is using a combination of microtunneling, slip-lining, and open cut techniques to install the outfall pipe, which will be tied into the existing outfall under the Lions Gate Bridge  (see outfall pipe alignment on map below).  Microtunneling and slip-lining use a limited number of above-ground access points (shafts/trenches/etc.). Microtunneling is a self-contained system which reduces noise, dust and impacts to the environment and travelling public.


    Microtunneling work was completed in September 2020.

    For the remainder of the outfall pipe, crews will use open cut techniques to complete pipe installation along eastbound West 1st Street, west of Philip Avenue. This will take place from September 2020 to September 2021. Traffic control personnel will be in place, as there may be some minor stoppages required. Please use caution while travelling in the area.

    This work takes place during regular work hours of 7 a.m. to 8 p.m. Monday to Friday, and 9 a.m. to 5 p.m. on Saturday. No work takes place on Sundays or statutory holidays. Access to local business will be maintained. 

  • Installation of Sewer Pipe: Deferred

    This section will be installed using open cut installation (locations C and D on map).

    • Work will be completed in sections to minimize disruptions. Microtunneling is not suitable for this part of the installation because the pipe is smaller in diameter, there are many utilities in the area, and connections need to be made to these utilities
    • Crews will remove sections of asphalt, lay down and connect the pipe, and replace the asphalt
    • This work has been deferred to align with completion of the North Shore Wastewater Treatment Plant Project
    • Advanced notification and information will be provided when this work begins

  • Temporary lane closures

    Work on West 1st Street (items A and B below) has been extended through to September 2021. The North Frontage Lane and Garden Avenue work (items C to E below) has been deferred to align with completion of the North Shore Wastewater Treatment Plant Project. More information will be provided in advance of this work. Please see map below for location details.

    A) Eastbound West 1st Street west of Philip Ave. (March 2019 – September 2021)

    • One lane of traffic will be maintained in each direction
    • North parking lane on West 1st Street from Garden Avenue to Philip Avenue temporarily closed to accommodate traffic shift
    • Cyclists will share the road with vehicles
    B) Westbound West 1st Street west of Garden Avenue (March 2019 – September 2021)

    • Local access only to this no exit block
    C) North Frontage Lane (Deferred)

    • Alternate access to local businesses from Welch St. via Garden Avenue and Philip Avenue
    • Temporarily close north parking lane and bicycle lane – cyclists will share the road with vehicles
    D) & E) Full Closure of the intersection of Garden Avenue at West 1st Street to install pipes (Deferred)

    • Detour for cyclists and vehicles via Philip Avenue and Welch Street
    • Access to local businesses will be maintained
    Please be advised that the North Shore Wastewater Treatment Plant Project is also completing additional pipe connections on West 1st Street from Philip Avenue to Pemberton Avenue through to spring 2021. Please visit their website www.northshorewwtp.ca for updates. Traffic management along West 1st Street is coordinated with these concurrent activities.
