City of Vernon, Mt Hawthorn, Perth – Western Australia.


To provide a 500m³ modular underground storm water infiltration tank system, under a large parking lot, that will withstand the weight of high weight bearing load vehicles.


VersiTanks 550 modules were assembled and interlocked on site, positioned in the excavated area that was lined with a geotextile layer. VersiTank 550 units were covered with 500mm of compacted aggregate and bitumen to engineering specifications, withstand the weight of high vehicle loads. Storm water from the adjacent shopping complex, the parking area and surrounding streets passes into a leaf/silt trap into the tanking system and then infiltrates into the sand substrate surrounding the VersiTanks.
