About this approved project
To plan for the future, the City is developing a long-term Residual Waste Disposal Plan. The Plan includes completion of an Individual Environmental Assessment (EA) for the expansion of the W12A Landfill which is expected to reach capacity in 2024. The individual EA requires approval by the Minister of Environment, Conservation and Parks.
The City is proposing to approximately double the current capacity of the landfill by increasing the maximum height of the existing waste footprint by 25 metres which will extend its life to 2049. In addition, the service area will be increased to a regional area, which includes: City of London, County of Huron, County of Perth, County of Elgin, County of Lambton, and County of Middlesex. The proposed design capacity for landfill expansion over the 25 year planning period is 9.9 million tonnes including 0.5 million tonnes from neighbouring municipalities (about 5%). The document Overview of the Proposed W12A Landfill Expansion provides details about why a vertical expansion was chosen and what changes will be made to the landfill when it is expanded.
