Largest single landfill cell in Victoria completed

In December 2019, Teneo completed the construction of Landfill Cell 5 for Wyndham City Council. The construction of Landfill Cell 5, the largest single landfill cell in Victoria, comprised of +450,000m3 of engineered fill, clay liner and aggregates, as well as +440,000m2 of geosynthetic liners.

Final leak detection was undertaken on the 6th of December with practical completion just prior to Christmas.
