Australian Tanks have a unique modular solution for sewer emergency storage tanks, catering for required storage volumes from 2,300 litres up to and over 500,000 litres.


Our Sewer Emergency Storage and Overflow Tanks are, as standard, constructed to an extra heavy duty rating:

  • Load rated up to unrestricted heavy vehicle access based on the SM1600 traffic design loads in accordance with AS5100.2 Bridge Design Code.

Combined with the trafficable construction, our tanks can support up to 1700mm of coverage over them. This provides a broad scope of options as to where they can be installed, giving you peace of mind they are rated for heavy duty traffic.

The solution Australian Tanks offer is based on two main strengths:

  • Quick and easy installation
  • Ease of maintenance.

Fast and Easy


Design Services For Increased Capacities 

10 Year Warranty
50 Year Design Life

Efficient Installation

Australian Tanks’ modular systems arrive to site with all fabrication completed in our factory, including benching in the tanks for ease of maintenance. Connection stubs are sealed-in for a quick and easy installation, and internally epoxy coated to protect the concrete from  hydrogen sulphide gases, ensuring a long-life design.

Our tanks incorporate an anti-floatation design, so even when the tanks are empty and installed in 100% saturation, there is no requirement for special ballasting.

Ease of Maintenance

Each tank has benching fabricated so that it is graded to a central channel. In the event of a pump station breakdown, or high level of ingress that causes the emergency storage to be utilised, once rectified the maintenance crew need only lift the lid on each tank and hose it down; the benching directs the flow back to the pump station.

As each tank has an access lid, the maintenance can be performed without confined space entry providing WHS benefits and genuine financial savings on maintenance.

  • Please Note: Australian Tanks manufactures heavy duty concrete tanks for civil and infrastructure projects on a commercial scale.

If you are a home owner seeking concrete water tanks, we highly recommend seeking a domestic product supplier within your locale.
