If you’re looking for a bunded diesel tank in Sydney, here’s the short answer: The Water Tank Factory supplies SmartBund™ self-bunded diesel tanks from 400 litres up to 10,000 litres, the maximum AS1940:2017 allows for diesel. We deliver factory-direct across the Sydney metro area, with prices starting from $2,375 depending on size, configuration and delivery.
Diesel storage comes with rules that AdBlue™ and general chemical storage don’t share, so getting the tank size and bunding right really matters — whether you’re setting up a depot, a construction site, or on-farm refuelling in Sydney’s outer areas.
What Is a Bunded Diesel Tank, and Why Does It Matter?
A bunded diesel tank holds your diesel inside an outer containment layer — the bund — sized to capture the full contents of the inner tank if it ever leaks or ruptures. Our SmartBund™ range builds that bund into the tank itself, so you get 110% containment and a compliant bunded solution without pouring a separate concrete bund.
That matters for two reasons. First, it protects your site, your stormwater system and your business from a costly spill. Second, most commercial and industrial sites need it, since a bund isn’t optional once you’re storing diesel at any meaningful volume.

Here’s the detail that catches people out: because AS1940:2017 caps self-bunded diesel storage at 10,000 litres, our larger SmartBund™ models — the 20,000L and 32,000L tanks — exist for AdBlue™ and non-flammable chemical storage only, not diesel. So if your site needs more than 10,000 litres of diesel on hand, that means multiple compliant tanks rather than one oversized one.
Every model in the diesel-eligible range shares the same integrated bund design, just scaled to different footprints, from a compact 900mm-diameter SB400 through to the 2,700mm-diameter SB10000.
You’ll also notice two price points for the 3,000L, 5,000L and 10,000L sizes. The Basic configuration gives you the tank, bund, camlock and fill pipe. The Bundle configuration (marked CAB) adds a lockable cabinet with a pump, filter, meter and level indicator, which is why it costs more — not because the tank itself changed.
Bunded vs Single-Skin Diesel Tanks?
We offer both bunded and single-skin diesel tanks, so the right choice really depends on your site.
SmartBund™ (self-bunded) suits most commercial and industrial sites in Sydney, because it meets bunding requirements without the space or cost of a poured concrete bund — a real advantage on tighter metro sites where every square metre of yard counts.
Single-skin tanks work well where bunding isn’t a regulatory requirement for your specific application, or where you’re pairing the tank with an existing bunded area. They’re a simpler, more budget-friendly option in the right setting, though they don’t include the built-in containment SmartBund™ offers.
If you’re not sure which applies to your site, our team can talk you through it — contact us with your site details.
Choosing the Right Bunded Diesel Tank Size for Your Site
Footprint is often the deciding factor on metro sites, so here are a few guidelines from our own model range:
SB700 to SB1,500 — compact footprints (900mm–1,250mm diameter), suited to smaller depots, single-vehicle fleets or tighter industrial yards.
SB2,500 to SB5,000 — a 1,600mm–1,980mm diameter footprint, a common choice for mid-size commercial sites and construction depots.
SB10,000 — the largest diesel-compliant option, at 2,700mm diameter, best suited to larger factory or depot sites where space allows and higher on-site storage genuinely cuts down refuelling trips.
Since every model can be configured as Basic or Bundle, it’s worth deciding early which one you need — that choice affects both the price and what turns up on delivery day.
Delivering Bunded Diesel Tanks Across Sydney
We deliver bunded diesel tanks factory-direct from our Alstonville facility in Northern Rivers NSW, the same facility that’s built poly tanks since 1984. Because site access and delivery zone both affect the cost, we quote freight against your specific address rather than a flat rate.
As the online sales division of Duraplas Industries, we manufacture every SmartBund™ tank in-house, carry BSI certification to AS/NZS 4766, and back every tank with a 5-year commercial warranty — not a tank bought in and relabelled.
Frequently Asked Questions: Bunded Diesel Tanks Sydney
What’s the maximum size diesel tank allowed in Sydney?
AS1940:2017 caps self-bunded diesel storage at 10,000 litres. Our SB10000 is the largest SmartBund™ model rated for diesel — larger models in the range suit AdBlue™ and non-flammable chemicals only.
Why do I need a bunded tank instead of a standard tank?
Because bunding provides secondary containment if the inner tank leaks or fails, it protects your site and stormwater system from a spill. Most commercial and industrial diesel storage requires it.
Do I need council approval to install a bunded diesel tank in Sydney?
Requirements vary by council and site use, so talk to your local council about your specific site before installing, particularly for larger volumes or sites near sensitive areas.
Can I get a single-skin diesel tank instead of a bunded one?
Yes, where bunding isn’t a requirement for your application. Since single-skin tanks suit simpler storage needs or sites with an existing bunded area, get in touch and we can advise which fits your setup.
How much does a bunded diesel tank cost?
Prices start from $2,375 for the SB400 and run to $14,450 for the SB10000CAB, our largest Bundle configuration. The exact price depends on tank size and whether you choose Basic or Bundle.
