Tank Solutions – FuelDiesel storage tanks
Diesel storage tanks for farms, mine sites, fuel depots, fleet yards, defence bases and data centre generators. We build above-ground steel diesel tanks, from self-bunded tanks that need no bund to single-wall bulk diesel tanks of up to 150,000L, and double-wall underground diesel tanks in fibreglass or Glasteel® II. Every tank is made in Australia at our ISO 9001 sites in NSW and WA.

Which diesel tank do I need?
Start with your site: how much diesel you need on hand, whether the tank goes above or below ground, whether you already have a bund, and how close it sits to buildings and boundaries.
| If you need | Choose | Why |
|---|---|---|
| A diesel tank with no bund to build, that can move later |  Self-bunded diesel tank | The double wall is the bund. Up to 110,000L of diesel, built to AS 1940 and AS 1692. |
| Diesel close to buildings, such as a generator tank |  Fireguard® 4-hour tank | Insulated double wall that is rated to the SwRI 4-hour fire test and can cut separation distances by up to 50%. |
| A fire rating with diesel and petrol in one tank |  Flameshield® 2-hour tank | 2-hour fire rated, with interstitial leak monitoring and a compartment for each grade. |
| Bulk diesel storage in a concrete bund |  Single-wall horizontal tank | 2,000–150,000L to AS 1692 Category 4, manifolded side by side for larger volumes. |
| An underground diesel tank with no corrosion |  Double-wall FRP tank | 2,000–150,000L, with Truchek® leak monitoring, up to 4 compartments and a 30-year corrosion warranty. |
| An underground steel diesel tank with FRP containment |  Glasteel® II tank | 2,000–200,000L under STI licence. The FRP outer wall removes the need for cathodic protection. |
Diesel tank sizes
A diesel storage tank can be built at any capacity from 2,000L, so a 5,000L or 10,000L diesel tank for a farm or workshop is built the same way as bulk diesel storage for a mine or depot: up to 110,000L of diesel in one self-bunded tank, 150,000L in a single-wall tank in a bund, and 200,000L underground in Glasteel® II.
| Diesel tank | Capacity | Containment | Installed |
|---|---|---|---|
| Self-bunded steel | 2,000–200,000L, with up to 110,000L of diesel per tank | Outer steel wall is the bund | Above ground |
| Fireguard® 4-hour | Built to order at the capacity you need | Insulated double wall, rated to the SwRI 4-hour fire test | Above ground, close to buildings |
| Single-wall horizontal | 2,000–150,000L per tank, manifolded for more | Concrete bund on site | Above ground |
| Double-wall FRP | 2,000–150,000L, with up to 4 compartments | Double wall with Truchek® leak monitoring | Underground |
| Glasteel® II | 2,000–200,000L | Steel tank inside an FRP outer wall | Underground |
| Flameshield® 2-hour | Built to order at the capacity you need | Double wall with interstitial leak monitoring | Above ground |

Bunded diesel tanks
Under AS 1940 a bunded diesel tank needs containment that generally holds at least 110% of the largest tank. You can get that two ways, and the choice mostly comes down to whether you already have a bund and whether the tank may move.
Self-bunded: the bund is built in
A self-bunded diesel tank is a tank inside a tank. The outer steel wall is the bund, so there is no concrete to pour, no rainwater collecting in an open bund, and the tank can be moved as the site changes. Every opening sits above the maximum liquid level, as AS 1940 Section 5.9 requires, so these tanks don’t gravity feed.
Single-wall: the tank sits in a concrete bund
A single-wall diesel tank sits in a concrete bund built on site. It suits fuel farms and sites with an existing bund, takes bottom outlets for flooded suction, and several tanks can share one bund. Rainwater that collects in the bund has to be caught and disposed of.
Diesel storage tanks made in NSW and WA
We build every diesel tank at our own ISO 9001 certified factories in Tomago NSW and Kwinana Beach WA, one on each side of the country, and deliver Australia-wide.
Built to order
There is no stock list to pick from. Each tank is built to the capacity, compartments and fittings your site needs. For a self-bunded tank, we send drawings with the dimensions and weight for your approval.
Freight in the quote
Every quote is priced with freight to your site, so the delivered cost is clear before you order, and we can coordinate the freight for you. A sales engineer covering your state replies within 2 business days.
Diesel storage and the standards
Above-ground diesel tanks
Under AS 1940, diesel is a Class C1 combustible liquid, not a flammable liquid like petrol, so the rules on bunding, location and separation are different. Our steel diesel tanks are built to AS 1940 and AS 1692, and self-bunded tanks carry their own bund. Read our plain-English AS 1940 guide, download our AS 1940 site checklist (PDF) to walk your site with, or see all above-ground fuel tanks.
Underground diesel tanks
Underground diesel tanks are double-wall, with the space between the walls monitored for leaks, and are installed by accredited installers. Fibreglass tanks are built to UL 1316. See what AS 1692 covers, or see all underground fuel tanks.
