The Twin Creeks Landfill is a regional facility that provides disposal services for communities, businesses and industries serving the Province of Ontario. This Landfill is approved to receive municipal, industrial, commercial, and institutional solid non-hazardous wastes generated, including non-hazardous contaminated soil. The landfill originally began operation in 1972. Waste Management of Canada Corporation (WM) has owned and operated the landfill since 1996.
The Landfill approved total airspace capacity is 26.5 million m3 over an area of approximately 101 ha.
Waste Management currently constructs internal haul roads by placing 600 millimetres of granular fill directly on existing waste. Generally the haul roads are used for two months to over twelve months and the granular material is not recovered.
Layfield with the expertise of Tencate provided an options analysis utilizing the RS280i, RS380i and RS580i products and were able to reduce the overall gravel thickness required by between 50% to 75% and providing a potential cost savings of approximately 30% (reduced material cost from $16/m2 to approximately $11/m2) on the haul road construction with this engineered solution. In addition, there is also a high likelihood that much of the granular material can be savaged and reused by using the geotextile as a separator cloth, further adding to the potential cost savings overall. Layfield has proposed a trial road construction of 2,500 m2 to assess the application at the Site
Waste Management is very interested in completing a 2,500 m2 trial haul road construction in the near future to ascertain if this solution proves true at their site.
