Rainwater Infiltration Systems

Ausdrain modules cloth being installed

The implementation of an infiltration system assists with the replenishment of underground aquifers and prevents stormwater discharge that may result in downstream flooding. The AUSDRAIN EnviroModule2 Infiltration Tank has proven to be one of the most efficient and cost-effective solutions to the environmental issues of stormwater management that have resulted in local authority requirements for infiltration tanks or soakaways.

The EnviroModule2 Tank is constructed from high strength EnviroModules that have been engineered to allow stormwater to be captured and efficiently discharged inside a structural void surrounded in geotextile fabric. Water entering the tank is stored temporarily and naturally dissipates back into the surrounding ground at a rate dependent on soil type. The AUSDRAIN EnviroModule2 tank can be installed in a variety of soil types due to the remarkable infiltration rates proven to be up to six times greater than gravel filled systems. The high compressive strength of the modules enables tank installations under trafficable areas such as carparks and driveways.
