INFILTRATION

Compared to conventional gravel systems, the AUSDRAIN EnviroModule Infiltration Tank offers 95% void storage that reduces tank sizing by up to two thirds saving on excavation and spoil removal costs.

The continued development of our cities and greenfields has resulted in the requirement to provide on-site water management systems. This enables the replenishment of underground aquifers and prevents stormwater discharge that may result in downstream flooding.

The AUSDRAIN EnviroModule 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 on-site infiltration and retention.

The EnviroModule 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 depending on soil type.

The AUSDRAIN EnviroModule 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.

Pre-filtering of stormwater is essential for a well designed system. Combined with the AUSDRAIN EnviroSump or a suitable Gross Pollutant Trap (GPT), this system provides a complete stormwater management solution.
