Why build a new wastewater treatment plant?




Metro Vancouver’s Integrated Liquid Waste and Resource Management Plan (ILWRMP), approved by BC Minister of Environment in 2011, identifies that the Lions Gate Wastewater Treatment Plant must be upgraded to secondary treatment by December 31, 2020.

Opened in 1961, the existing Lions Gate Wastewater Treatment Plant 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 Wastewater Systems Effluent Regulations are posted on this federal website.

For information about Metro Vancouver’s commitment to secondary treatment upgrades, view pages 18-19 in the Integrated Liquid Waste and Resource Management Plan PDF below.


The 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.
