Bigger household, longer dry spells
15,000 litres is the next step when the 11,250L isn’t cutting it. That’s bigger families, larger roof catchments, or blocks that run through stretches of 6-to-8 weeks without useful rain. An extra 4,000 litres over the standard rural primary tank, on a footprint that still fits most pads.
Corrugated wall, built tall
3,100mm diameter, 2,200mm tall, corrugated construction. The wall profile handles hydrostatic load at full fill without bulging or stress-cracking. One-piece moulded polyethylene, so there are no welds or seams to split as the tank cycles between empty and full across the seasons.
Clean water by design
UV-stabilised, food-grade LLDPE, AS/NZS 4766 compliant for drinking water. Safe for the kitchen, safe for stock, safe for anything you’d run off a rural catchment. No internal lining to fail a decade in.
Where it earns its spot
Primary household supply on larger rural builds. Second tank upsized from an old 10,000L galvanised. Combined household-and-garden capacity where the owner doesn’t want to trust a single tank. Off-grid properties with a second dwelling or workshop on the same catchment.

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.
