Prefabricated Stormwater Tanks

Prefabricated Stormwater Tanks are customisable, 100% waterproof, HDPE lined and welded stormwater system, greatly saving contractor’s time as they are supplied ready to simply drop into site.

Prefabricated Stormwater Tanks save valuable construction time and workspace on site. With an internal void space ratio of over 95%, Prefabricated Stormwater Tanks are built off-site, lined with thick, robust HDPE and weld sealed, creating a 100% waterproof solution. They are wrapped in geotextile, then delivered to site where and when you need them. Once all ground prep is done, the lightweight units are simply lifted into place. 

With a modular design and structural capabilities, Prefabricated Stormwater Tanks distribute loads evenly and allows for usage in both trafficable and landscaped areas offering a high safety factor. The system can be integrated into traditional pavement designs without the need for additional concrete slabs for protection.

Having a ready-to-install Prefabricated Stormwater Tank delivered directly to site saves valuable contractor time. Prefabricated Stormwater Tanks are customisable to fit site specifications, including dimensions, pipe numbers and pipe placement. Standard units of 2.5m3, 5m3 and 10m3 are available, but Prefabricated Stormwater Tanks can be adjusted to meet any supplied design. 

Frequently Asked Questions

Although we have standard modules available, Prefabricated Stormwater Tanks are designed so you can customise the dimensions to suit your specific site requirements. This can include height, width and depth, the number and size of pipes required as well as their placement. 

Each unit is fully wrapped with a thick, hard-wearing HDPE liner and weld sealed to ensure remaining 100% waterproof. The liner is also wrapped and weld sealed around the pipe extrusions.  This is done offsite in a clean environment, meaning no contaminants get inside the tanks before being sealed.  The tanks are then wrapped in geotextile before being delivered to site.  

Depending on the design specifications, large modules may be able to be split into smaller units for ease of delivery and placement and connected with pipes for desired water management. This could also be considered for irregular shapes.
