Duraplas Round Water Tanks

Duraplas round water tanks are a popular choice for homes, farms, rural properties and commercial sites where there is enough open space for the tank diameter.

Round poly tanks usually offer excellent strength and value per litre. The Tank Factory supplies Duraplas round tanks from compact models through to large rural water storage tanks up to 34,000 litres.

Duraplas Slimline Water Tanks

Duraplas slimline water tanks are suited to narrower spaces such as beside a house, along a fence line, near a shed or in a side passage.

Slimline tanks are useful when a round tank would take up too much room, while still providing practical rainwater storage for gardens, household use and outdoor projects.

Duraplas Underground Water Tanks

Duraplas Lattice™ underground water tanks are designed for below-ground water storage where above-ground space is limited or where the tank needs to be hidden from view.

The underground range includes yard and driveway models, giving customers options for different installation areas and site requirements.

Why Choose Duraplas?

Duraplas poly tanks are designed for Australian conditions and are available in a wide range of sizes, shapes and colours. Product pages show the relevant specifications for each model, including capacity, dimensions, fittings and installation notes.

The Tank Factory supplies Duraplas tanks factory direct, with clear online pricing and delivery information. A proven 20-year warranty (10 + 10) applies across many Duraplas poly rainwater tanks.

Compare Duraplas Tank Sizes

If you are comparing Duraplas tanks, start with the available space on your site, the amount of water storage you need and the access available for delivery and installation.
