Poly Underground Tanks
We offer a range of poly and concrete underground tanks if you don’t have enough space for an above ground tank. You can landscape over the tank, leaving only access to the service lid
Poly Underground Tanks:
Underground tanks free space around your home and are hidden out of sight. We offer a range of polyethylene underground tanks so that you can save water and help the environment by minimizing the amount of water going to the stormwater system. You can landscape over the tank, leaving only an access lid visible.
Our underground polyethylene tanks are exceptionally strong, thoroughly tested to meet Australian Standards and can be fitted with a poly lid for pedestrian traffic, or a riser and cast-iron lid for heavy-duty use. These tanks are ideal for rainwater holding tanks and on-site detention tanks. Specific installation instructions apply to underground tanks.

Aquarius Watermaster supplies the German designed Graf Li-Lo Underground tanks. These tanks are now manufactured in Australia to the highest standards.
Their low profile means less digging than alternative tanks, and they do not require concrete ballast.
The tank is available with a PE childproof pedestrian lid as standard or an extension riser and a trafficable lid as an optional extra.
Link tanks together with the Graf proprietary seals to increase capacity.
