The leachate ponds are designed as two separate ponds which will provide efficient leachate treatment while providing an adequate safety net for unforeseen storm events.
The ponds are constructed with a HDPE (High Density Polyethylene) layer on top of a cushion of geotextile, and both are placed over a one metre thick clay layer.
These leachate ponds will service Cosgrove 3 for the whole of life providing efficient landfill waste disposal.
Watch the latest time lapse footage showing the construction of leachate ponds which will service the new Cosgrove 3 landfill.
