Engineers at Queen’s University help Barrie modernize its municipal landfill and, in the process, save its taxpayers millions of dollars
August 7, 2012

Using technology tested at Queen’s University’s GeoEngineering Centre, the City of Barrie saved its taxpayers some $10 million. Barrie wanted a long-term solution to protect the aquifer feeding its drinking water system, located under an aging landfill in the middle of the city. In building a new landfill, it became the first city in Ontario to use a geosynthetic clay liner, a product that had been permitted in Ontario since 1998 but had never been approved by the province’s Ministry of the Environment because of a lack of research.

Researchers at the GeoEngineering Centre showed that the geosynthetic liners performed better than natural clay liners. This helped the city get clearance from the province to use the material and saved it the $10 million it would have cost to transport thousands of truckloads of clay to the site.
