Infiltration Tanks and Soakwells

There is growing interest in infiltration as an alternative or supplement to conventional drainage techniques due to its many environmental and economic benefits. These benefits include reduced peak stormwater flows, reduced stormwater drainage capital costs, improved groundwater recharge and improved stormwater quality.

Ausdrain EnviroModule™2 Infiltration Tank offers 95% void storage that reduces tank sizes by up to two thirds of the traditional gravel infiltration, saving on excavation and spoil removal costs.

A further advantage of Envirnmodule2 is that it is a modular system which provides flexibility of size and shape as well as the reduced time and cost of installation.

The EnviroModule™2 Infiltration Tank is constructed from high strength EnviroModule™s 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 high compressive strength of the modules enables tank installations under trafficable areas such as carparks and driveways when installed in accordance with installation guidelines and engineer’s specification.

Ausdrain modules are ideal to manage storm water at sports fields, schools and universities, shopping centres, service stations, recreational areas, carparks and commercial projects
