Metro Vancouver | Conveyance for North Shore Wastewater Treatment Plant Project

August 18, 2017

Project status

Permit under review

In October 2017, Metro Vancouver submitted a project permit application for the Conveyance for North Shore Wastewater Treatment Plant in North Vancouver, British Columbia on federal lands and waters managed by the Vancouver Fraser Port Authority.

As part of the Project and Environmental Review for the proposed project, consultation with stakeholder and Aboriginal groups is required. The port authority is conducting formal consultation activities with stakeholders as part of the permitting process. The port authority has delegated the procedural aspects of Aboriginal consultation to Metro Vancouver and will review Metro Vancouver’s record of Aboriginal consultation, as part of the port authority’s permitting process, to ensure the duty to consult has been adequately fulfilled.

About the project

The existing Lions Gate Wastewater Treatment Plant, situated just to the west of the Lions Gate Bridge, opened in 1961 and serves the North Shore municipalities of West Vancouver, the City of North Vancouver, and the District of North Vancouver. 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.

The new North Shore Wastewater Treatment Plant will be built on a new Metro Vancouver-owned site in the District of North Vancouver, approximately 2 km east of the existing treatment plant. The existing plant will be decommissioned and the lands returned to Squamish Nation in accordance with a Provincial/Federal cut-off lands agreement.

Metro Vancouver proposes to construct a pump station and sections of both gravity main and force main conveyance pipe within the port authority’s jurisdiction.

Proposed project activities and components include:

Bridge Road Pump Station

  • Construction of an enclosed pump station in an architecturally designed building measuring approximately 13 m (42.7 ft.) high x 22.5 m (73.8 ft.) wide x 30 m (98.4 ft.) long, for a footprint of 675 m2 (7,265 ft2);
  • Excavation (for the pump station) to an approximate depth of 11 m (36 ft.);
  • Installation of utility connections (electrical and potable water), and mechanical and electrical systems, including pumps, odour control unit, standby generator, and HVAC;
  • Construction of roadway to, and around, site for fire truck access and paved parking for operations and maintenance staff;
  • Installation of hardscaping, and low maintenance landscaping that incorporates plantings and grassed areas;
  • Installation of associated exterior and interior lighting systems; Exterior lighting comprised of wall mounted and stand-alone LED’s;
  • Installation of a chain-link/rigid wire security fence measuring approximately 2.4 m (7.8 ft.) high, with locked access gate;

Sewerage Conveyance Pipes

  • Construction of approximately 75 m (246 ft.) of 1200 mm diameter Hollyburn Interceptor extension pipe, from the port authority’s northern jurisdictional boundary southward to the new pump station. Interceptor extension pipe conveys sanitary wastewater from the District of West Vancouver;
  • Construction of approximately 30 m (98.4 ft.) of 900 mm diameter sanitary influent force main from the new pump station northward to the port authority jurisdictional boundary. Force main continues onward and connects with the new proposed North Shore Wastewater Treatment Plant;
  • Construction of approximately 170 m (557.7 ft.) of 2100 mm diameter effluent line from the port authority’s northern jurisdictional boundary southward, and then westward, to a tie-in at the air chamber on the existing outfall. Effluent line originates at the new North Shore Wastewater Treatment Plant. Total surface disturbance footprint for all three lines is approximately 2,950 m2  (31,753 ft2);
  • Excavation (for the Interceptor, forcemain, and effluent line) to an approximate depth of 8 m (26.2 ft.); and,
  • For entire project, removal and importation of approximately 85,000 m3 (111,176 yd3) and 40,000 m3 (52,318 yd3) of soil, respectively. Engineered modification of soil to facilitate project excavations.

Please note that all dimensions and quantities are approximate. Should the proposed project be approved, construction is expected to take approximately 2 years, with construction starting in Q3 2018, pipeline commissioning in Q3 2019, and pump station commissioning in Q2 2020. Construction vehicle volumes are anticipated to peak (20-30 trucks/day) approximately six months after construction start and last an additional six months. Construction vehicles associated with works within the port authority’s  jurisdiction will travel westbound along a temporary easement situated to the immediate north of the rail tracks, and then southbound onto Bridge Road, to access the proposed Bridge Road Pump Station. Exiting vehicles will proceed north on Bridge Road and eastbound on the temporary easement, subject to attainment of applicable external permits.
