Water Tanks Tasmania

Slimline tanks solve the “we don’t have room for a round tank” problem. A narrow rectangular footprint that sits flat against a wall, fence, or under an eave. So you can catch roof water on a tight suburban block, a heritage frontage, or a side passage where a round tank would never fit.

The construction is the same UV-stabilised LLDPE polyethylene as the round range, food-grade compliant under AS/NZS 4766, and safe for potable water. The geometry is the only difference. Taller and narrower, with reinforced walls that handle the hydrostatic load without bowing.

Sizes from 1,000 L through to 5,000 L. The smaller end suits inner-suburban Tasmanian homes adding rainwater for the garden, toilet, or laundry to take pressure off mains. The larger end works as a primary tank on a long, narrow site, or as a second tank tucked beside an existing round one to add capacity without taking more ground.

22+ Colorbond colours across the range, so the tank can match the wall it sits against and disappear from the streetscape. Spin it in 3D to check the proportions before you buy.

Common picks: townhouse and unit owners adding catchment, heritage homes where the front yard is fixed, and rural builds where the slimline fits a covered alcove the round tanks miss. Tasmanian-made. Free delivery to most of the state. 15-year prorated warranty.
