Conveyance Project Updates
In September 2019, the Project team issued the first edition of the Conveyance Project community newsletter, which can be viewed
. This edition includes community engagement to date, how the Conveyance Project relates to the overall North Shore Wastewater Treatment Plant Program, and a general update on Project activities. If you would like to sign up to receive the next edition, please email
Installation of Outfall Pipe: March 2019 – September 2020
The Project is using a combination of microtunneling, slip-lining, and open cut techniques for the installation of the outfall pipe (see outfall pipe alignment on map below). Microtunneling and slip-lining use a limited number of above-ground access points (shafts/trenches/etc.) to limit surface impacts.
- Microtunneling is a self-contained system which reduces noise, dust and impacts to the environment and travelling public.
- This method of ground improvement limits noise, while still creating the watertight structure required for microtunneling.
- The new pipe will be tied into the existing outfall under the Lions Gate Bridge.
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
The Project will use open cut installation for this component (locations C and D on map below).
- Work will be completed in sections to minimize disruptions. Microtunneling is not suitable for this component as the pipe is smaller in diameter and there are many utilities in the area and connections are required.
- 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 commences.
Temporary lane closures
Work on West 1st Street (items A and B below) has been extended through to September 2020. 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 2020)
- One lane of traffic will be maintained in each direction
- Cyclists will share the road with vehicles
B) Westbound West 1st Street west of Garden Ave (March 2019 – September 2020)
- Local access only to this no exit block
C) North Frontage Lane (Deferred)
- Alternate access to local businesses from Welch St. via Garden Ave. and Philip Ave.
- Temporarily close north parking lane and bicycle lane – cyclists will share the road with vehicles.
D) & E) Full Closure of the intersection of Garden Ave. at West 1st St. to install pipes (Deferred)
- Detour for cyclists and vehicles via Philip Ave. and Welch St.
- Access to local businesses will be maintained
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 the mid-2020s and the land returned to Squamish Nation.
