Water Tanks Tasmania

Poly tanks are the practical default for most Tasmanian rural blocks. One-piece moulded LLDPE (Linear Low Density Polyethylene), with no seams, no welds, and no internal lining to fail. Lighter than steel, easier to position, and immune to the rust and electrolysis problems that age out metal tanks.

Built for Tasmanian conditions: UV-stabilised polymer that doesn’t chalk or crack in coastal sun, flexible enough to absorb ground movement on bush blocks, and food-grade compliant under AS/NZS 4766. Safe for potable water from day one.

Sizes scale from small 500 to 2,400 L tanks for sheds, top-ups, and tight corners, through to 22,000 L tanks for primary household catchment off a full roof. The round footprint is the most efficient use of poly per litre stored, so you get the best price-per-litre in this range.

22+ Colorbond-matched colours across the range. Pick a colour that blends with your roof, fascia, or fence, or vanish it into the bush with a muted earth tone. Spin every tank in 3D before you buy to see footprint, height, and proportions on your site.

Common Tasmanian use cases: primary supply on off-grid builds, replacement for failed steel tanks, secondary catchment for irrigation or fire reserves, and tradie-spec’d installs on new rural builds. Tasmanian-made. Free delivery to 90% of the state. 15-year prorated warranty on every tank.
