Mango Hill, Queensland


Australian Tanks were specified on plan to provide 2 x 133,000L underground trafficable detention systems.

Both systems required multiple efficiencies in install time and site costs.  Located under a thoroughfare road, it was essential to have prompt delivery with lowering and positioning of the tanks a priority to avoid construction delays and OHS issues with an open excavation for any extended period of time.
