Background on the Humberstone Landfill

The landfill is a 38 hectare site that is operated for the disposal of domestic, commercial and non-hazardous solid waste. The landfill has been in service since the 1940s. The landfill site has extensive infrastructure.

In the late 1990s a leachate collection system was constructed to ensure that leachate produced by the landfill is contained on-site and treated at a municipal waste water treatment plant.

Also in the 1990s, four stormwater detention ponds and a perimeter ditch network were constructed to ensure that all surface water running off the landfill is captured and tested prior to being released off-site.

In accordance with Ministry of the Environment requirements, the first phase of a landfill gas collection system has been installed and is operational.
