The AUSDRAIN™ EnviroModule Re-use System is a cost-effective and flexible solution to underground stormwater storage requirements. The high compressive strength and durability of the modules enables them to be installed in light to medium trafficable areas such as; under driveways and carpark areas, thus making the most of valuable and often limited land space.

The required number of EnviroModules are used to create the storage capacity. There are 9.6 modules required to create 1000 litres of storage. Therefore, you would require 96 modules to create a 10 000 litre tank.

The modules are then encased in either a factory welded liner that is made to size as per the specification or a Low Density Polyethylene Membrane (LDPE) depending on job requirements. Both liners meet Australian Standards AS2070 Part 2 for potable water use.

The AUSDRAIN™ EnviroSump(s) or a Gross Pollutant Trap (GPT) filters the water before entry into the tank avoiding the need for long term and costly tank maintenance. In the event that the tank surcharges, excess water is discharged through an overflow pipe to a designated outlet.

Finally, a suction line is inserted inside the tank and connects to an above ground pump system. The pump is selected according to irrigation and pressure requirements.

The modular flexibility of the system gives designers the scope to specify tank dimensions that best suit a particular project.
