Squat profile for low eaves
At 1,040mm tall the 1,100L is one of the shortest tanks in the range. If you’ve been measuring under a verandah, a carport beam, or the slope of a rural shed skirt and coming up short on clearance, this is the capacity that still fits. The wider 1,350mm footprint gives you volume without the vertical lift.
Where it earns its spot
Rural sheds where the tank sits beside machinery under a fixed roof. Suburban side yards with a deck on one side and a fence on the other. Stock troughs fed from a modest shed catchment. Garden-only supply on a block where drinking water comes from a bigger tank elsewhere.
Clean water from day one
Moulded in one piece from food-grade LLDPE polyethylene, UV-stabilised, and AS/NZS 4766 compliant. Safe to drink, safe to cook with, safe for stock.
Fittings sorted out of the box
Brass bibcock, 300mm strainer basket with stainless steel insect mesh, 90mm overflow with Rapid Seal grommet and removable screen, and BSP female outlets. No mid-install trips to the plumbing supplier.
Tasmanian-made. Delivered.
Moulded in Tasmania. Free delivery to 90% of the state, no freight surprise at checkout. 15-year prorated warranty on every tank. 22+ Colorbond-matched colours to blend with the roof, fence, or bush.

Warranty Policy
Our warranty policy ensures peace of mind, covering defects and issues under standard terms.
Payment Information
We accept VISA, Mastercard, Google and Apple Pay.
How long will it take to arrive?
Most tanks reach your block within two weeks of order. Every tank is made in Tasmania and delivered direct, so there’s no mainland freight wait. If you’ve got a critical date (plumber booked, build sign-off, certifier inspection), let us know at order time and we’ll flag any timing risk
Do you install the tank or sort the plumbing?
No. We deliver to your block and unload. Connecting it to your downpipe, pump, and house plumbing is a job for your plumber. On a new build the plumber usually has the inlet, outlet, and overflow rough-in ready before the tank arrives.
Do I need council approval to install a water tank?
For most rural and residential properties in Tasmania, a standalone rainwater tank doesn’t need council approval. Larger tanks, elevated tanks on stands, and tanks in heritage zones can have local rules, so a quick check with your council before you order is worth the five minutes. Fire fighting tanks tied to a building permit are usually approved as part of the build itself.
Can I pick the colour?
Yes. Most ranges come in 22+ Colorbond colours so you can match a roof, fascia, fence, or pick something that disappears into the bush. Use the colour picker on the product page. The live colour shows on the 3D tank view so you can see exactly how it’ll look before you check out.
What if I order the wrong size or change my mind?
Get in touch as soon as you can. If the tank hasn’t begun manufacturing, we may be able to change the tank colour or size. Unfortunately, once manufacturing starts (as all tanks are custom-made), we can’t accept returns.
