Septic Risers
Australia’s only lightweight septic tank riser
Many septic tanks are completely buried underground, making maintenance difficult. Without good access or knowledge of the tank’s location, regular maintenance is often not conducted, which allows untreated sewage to flow into the disposal area. Our lightweight septic risers make excavation headaches a problem of the past by facilitating fast, safe, and easy access to your septic tank.
Nationally approved & rigorously tested
Extensively researched, rigorously tested, and developed in partnership with BioSeptic, the septic tank riser assembly is Australia’s only nationally approved lightweight septic tank riser assembly, delivering innovation, reliability, and compliance. It fits over existing septic tanks and raises the access cover to ground level, making it fully accessible. Once installed, there’s no more inconvenient digging. Maintenance becomes hassle-free and straightforward.

Weighing just 9kg, the cover is designed for easy, one-person lifting while meeting Work Health and Safety guidelines.
Built to Standards
Designed to meet AS/NZS 1546.1, ensuring every system allows for safe desludging and long-term reliability.

Engineered to withstand over 1.5 tons of pressure, ensuring long-term performance under heavy use.
Septic tank risers for easy access & leak-proof protection
The riser assembly makes it easy to find, open and access septic tanks to pump out the contents and quickly re-seal the lockable cover. The septic tank riser assembly is gas tight to contain odours, and watertight to prevent both effluent leaking from the septic tank to the surrounding area, and ground water from entering the septic tank.
Our superior lightweight alternative to the traditional concrete riser and lid weighs a mere 22kgs for the saddle, 9kg for the lid and 5kg for the sealing ring. All parts come separately for easy handling and installation, and the complete assembly has been tested to withstand a massive 1.5 tonnes of superimposed pressure.

Septic tank riser frequently asked questions
Why do I need a riser?
Risers provide easy access to the septic tank for de-sludging, maintenance and repairs, saving on digging costs.
How do I know if I need a riser?
If the lids on your septic tank are buried, installing a riser is recommended as it is a requirement that all septic tanks are to have access openings at ground level for de-sludging and maintenance.
How do I install a riser?
Installing a riser is generally a job best left to professionals; however, they are easily installed if you wished to do it yourself. Installation instructions come with every riser sold.
Will a riser affect the appearance of my yard?
Our risers are aesthetically pleasing and can be installed flush with the ground or with a slight protrusion.

Well done in bringing this product to the market
Hi Rob. Just wanted to pass on how pleased I am with your tanks. You have bridged the gap with a product that addresses the problems with the light weight poly products and the heavy concrete tanks. You have a brilliant design that will not split or distort as the poly tanks do or delaminate in a corrosive or acidic environment that will destroy any concrete tank. They do not need any heavy lifting equipment to install or transport and have a riser system that can be adjusted to suit the ground level perfectly without the need to position the tank to suit this. A truly brilliant product that will give years of service. Well done in bringing this product to the market. Kind regards, Wayne

These products whether it’s 3,000 or 30,000 ltr tank you need or just the riser they can do it.

The saddle and riser worked out perfectly
The saddle and riser worked out perfectly. Easy to put in place – a brilliant design in it’s simplicity. I’m very happy that I came across you online. The pump out boys (Alexandrina council) we’re seriously impressed too – I’m guessing they’re hoping a lot more people put them in place too (save their backs)!
