The RainSmart® modular tank system is suited for subsurface infiltration, retention and detention stormwater applications.

The modules are manufactured using recycled materials and provide a lightweight, structural component to an engineered design. The system is ideally suited for the construction of underground infiltration, retention, detention tanks, grass swale, subsurface interception channels, septic leach drains and lightweight void fillers for roof garden and planter box applications.

The RainSmart system supersedes traditional gravel and pipe-based systems. The system provides a void space ratio of over 95%, compared to 30 – 40% in typical gravel and pipe based systems. Consequently, the RainSmart system offers a smaller footprint for the same storage volume. This provides a significant saving in the amount of excavation, soil transport, imported clean aggregate, thus reducing earthworks related installation costs and causes minimum site disruption.

RainSmart Stormwater Modules

The modules are available in kit form, making transporting economical and easy to handle. The lightweight and stackable nature of the tank modules ensures installation is quick and easy, eliminating the use of heavy machinery.

Frequently Asked Questions

Whether you need to hold stormwater (detention system), soak water away (infiltration system) or detain water to release at a controlled rate (attenuation system), RainSmart will provide a simple, cost effective and maintainable underground stormwater management solution for your site.

We are a supplier of RainSmart and related materials only. However, we do have a network of experienced contractors that we can recommend for RainSmart installations.

Geogrid must be placed 300mm above the RainSmart system. Overlap adjacent panels by 300mm minimum or as specified in plans. Geogrid should extend 1m beyond the footprint of the RainSmart tank. In areas with lighter residential traffic, this can be reduced to 500mm.

Non-trafficable areas with 0.3m to 2m of cover should use 4-Plate modules. Trafficable areas with 0.6m to 2m of cover should use 5-Plate modules. Please note, the RainSmart plate configuration shall be specifically designed by the project engineer for installations with more than 2m of cover or trafficable applications with less than 600mm of cover. 7-Plate modules will likely be required for these applications.

When an impermeable liner is required, the liner used will depend on the application and size. Typically, folded PVC liners are used for smaller residential applications and welded FPP or HDPE liners are required for more significant or critical applications.

RainSmart modules are supplied flat packed and will need to be assembled on site. Building the modules should take 2-3 minutes per module layer. This is a conservative estimate used to approximate the total man hours needed for assembly (refer to page 5 of the RainSmart Installation Guide). Note that this time frame relates to assembly only. The time required to place the modules within the excavation will be dependent on site accessibility and layout. If practical for your site, installation can be sped up by assembling the modules in the excavation.
