Conveyance Project Updates
Site preparation activities for the new pump station have been underway since November 2018, including caisson construction which strengthens the ground in advance of the foundation work.
In order to complete this work safely and efficiently, NSCP received approval from the Vancouver Fraser Port Authority to temporarily extend working hours at the pump station site.
What to Expect
- Caisson construction involves drilling holes and then filling the holes with cement to strengthen the ground.
- Completing this work during extended hours improves site safety by allowing crews to maneuver equipment while no other work is underway.
- Extended work hours will be in effect Monday through Saturday from 8 p.m. to 11 p.m. starting mid-January 2019 through to February 28, 2019. No work will be done on statutory holidays.
- This temporary extension is only for ground improvement activities at the pump station site located under the Lions Gate Bridge (approximately 275 metres south of the railway tracks).
- All other Project work, including cement deliveries to complete the caissons, will take place during regular work hours of 7 a.m. to 8 p.m. Monday to Saturday. No work will take place on Sundays or statutory holidays.
If you have any questions or concerns about this work, please contact the Project’s Community Liaison Officer at 778-382-9011 or by email at NSCPsupport@kenaidan.com.
Conveyance Project construction began in November 2018, with Project completion anticipated late 2020.
A public open house was held on October 25, 2018 and the feedback period on construction mitigation is closed. See the
Open House Display Boards for project information.

The Lions Gate Wastewater Treatment Plant, situated just to the west of the Lions Gate Bridge, serves the North Shore municipalities of West Vancouver, the City of North Vancouver, the District of North Vancouver, and Squamish Nation. The plant is one of two remaining primary treatment plants in the region.
New federal regulations require all primary treatment plants be upgraded to secondary treatment by December 31, 2020. Secondary treatment is a biological process that uses aerobic bacteria to consume suspended solids and dissolved organic materials in wastewater. Secondary treatment plants remove about 95 per cent of the organic materials in wastewater. The new facility will provide a higher level of treatment to the North Shore’s wastewater before it is sent into Burrard Inlet.
In July 2018, Metro Vancouver awarded the North Shore Conveyance Partners (NSCP) the contract to design and construct a pump station and related pipes to convey wastewater from the existing Lions Gate Wastewater Treatment Plant to the new North Shore Wastewater Treatment Plant that is currently under construction on West 1st Street between Pemberton Avenue and Philip Avenue.
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. The Conveyance Project includes the following components:
- Constructing a
new pump station located at south end of Bridge Road underneath the Lions Gate Bridge
- Installing a 1200 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 2100 mm
effluent sewer pipe extending from the new North Shore Wastewater Treatment Plant to the existing outfall
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 2022/2023 and the land returned to Squamish Nation.
