Tank material Aquaplate steel

The goldilocks Aquaplate

1,680mm wide, 1,550mm tall, 3,400 litres. Balanced in both directions. Not too tall to dominate a sightline, not too wide to take the yard. Fits comfortably on a standard 1,780mm concrete pad. The mid-range Aquaplate most rural blocks default to when they want steel construction without silo-scale presence.

Why Aquaplate

Aquaplate is Zincalume-coated steel outside, food-grade polymer lining inside. Steel for the strength, corrugated look, and coastal-tolerant UV life. Polymer lining for drinking-water compliance (AS/NZS 4020), no metallic taste, and no rust pitting from the inside out. The best of both construction types in a single tank. No lining to fail mid-life, no metal contact with your water.

Where it lands

Primary supply on a one- or two-person rural cabin. Secondary tank on an established rural block adding capacity without expanding the main system. Replacement for an aging 3,000L plain-steel tank where the owner wants potable-water compliance on the upgrade.

Fit-up included

400mm strainer basket inlet with stainless steel insect mesh, 90mm Rapid Seal overflow with removable screen, brass bibcock. Outlets placed on request.

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.
