Self-Bunded Diesel and Chemical Storage in South Australia: What SA Businesses Need to Know

South Australian businesses run on stored liquids. Diesel for headers on the Eyre Peninsula. AdBlue for trucks running the Dukes Highway. Cleaning chemicals for Adelaide laundries and wineries across the Barossa. Yet safe, compliant self-bunded storage in South Australia has often meant long waits or costly freight from interstate suppliers.

That has now changed. The Tank Factory delivers its Australian-made SmartBund™ self-bunded tanks direct to South Australia. So this is the right time to look at what SA businesses need to know — from EPA SA rules to choosing the right tank for your operation.

A self-bunded tank is a tank within a tank. The inner tank holds your diesel, AdBlue or chemicals. The outer tank acts as a built-in bund — a containment layer that captures any leak or spill before it reaches the ground.

Our SmartBund™ range takes this further. The outer bund holds 110% of the inner tank’s capacity. As a result, even a complete failure of the inner tank stays fully contained. Traditionally, businesses met their bunding obligations by building concrete bund walls around a standard tank. That approach works, but it costs thousands in civil works and eats up valuable yard space. A self-bunded tank removes that requirement in many applications. You get compliant containment in one compact, transportable unit.

South Australia takes liquid storage seriously, and for good reason. Much of the state drains toward the Murray, coastal waters or precious groundwater. Here’s how the regulatory framework fits together.

The Environment Protection Act 1993 places a general environmental duty on every SA business. In short, you must take all reasonable and practicable measures to prevent environmental harm from your activities. Storing fuel or chemicals without proper containment falls well short of that duty.

On top of this, the Environment Protection (Water Quality) Policy 2015 prohibits pollution of stormwater and natural waters. EPA SA’s bunding and spill management guidelines spell out the expectation clearly: liquids other than rainwater should sit within compliant bunding. A spill that reaches a drain can mean clean-up costs, penalties and lasting damage to your reputation.

South Australia also runs its own dangerous substances licensing under the Dangerous Substances Act 1979 and the Dangerous Substances (General) Regulations 2017, administered by SafeWork SA. Depending on what you store and how much, licensing or notification obligations may apply.

Sitting underneath all of this is AS1940:2017 — the Australian Standard for storing and handling flammable and combustible liquids. It covers tank design, bunding, separation distances and signage. Diesel is classed as a combustible liquid under this standard, which is why compliant diesel tanks are capped at certain sizes without additional controls.

The practical takeaway? Storage quantities and site conditions determine your exact obligations. Before installing bulk storage, confirm your requirements with EPA SA and SafeWork SA. Then choose a tank designed to meet AS1940:2017 from day one — because retrofitting compliance is always more expensive than buying it built in.

From the grain country of the Eyre Peninsula and Mid North to the Riverland’s irrigated blocks, SA farms depend on diesel. Harvest doesn’t wait for a fuel delivery. On-farm storage means machinery keeps running, and buying in bulk lets you purchase when prices dip. A SmartBund™ tank also handles AdBlue and many farm chemicals, so one storage solution covers multiple needs.

SA’s resources sector operates in some of the most remote country in Australia. Reliable on-site fuel keeps generators, haul trucks and drilling rigs working. Self-bunded tanks suit these sites perfectly — they arrive ready to use, need no concrete works, and can relocate when the project moves.

Adelaide’s growth corridors and regional infrastructure projects all run on diesel. Consequently, site managers need storage that ticks the compliance box without slowing the job down. A self-bunded tank drops onto hardstand and starts working the same day.

Adelaide sits at the crossroads of the nation’s east–west and north–south freight routes. For depot operators, on-site diesel and AdBlue storage cuts refuelling downtime and takes the sting out of retail fuel pricing. Lockable pump cabinets add security against fuel theft — a genuine cost for fleet operators.

Here’s one that’s distinctly South Australian. Wineries in the Barossa, McLaren Vale and Riverland store cleaning and treatment chemicals as part of everyday production. So do food processors across the state. SmartBund™ tanks safely store a wide range of chemicals, from sodium hydroxide to hydrogen peroxide, with full secondary containment built in.

SmartBund™ tanks are engineered and manufactured in Australia by Duraplas Industries — a family-owned company with the same owners since 1984. Every tank is rotationally moulded in one piece from UV-stabilised polyethylene, built for harsh Australian conditions. Poly won’t rust, which matters in coastal and high-use environments.

• Eight capacities from 400 litres up to 32,000 litres
• Diesel options up to 10,000 litres, in line with AS1940:2017
• Outer bund with 110% containment capacity
• 5-year commercial warranty, plus a 12-month pump warranty where fitted
• No concrete bund required in many applications

You can choose the tank and bund only, or add a complete dispensing setup. Bundle options include a 60 L/min pump, nozzle, filter, meter, level gauge and weather-resistant cover. For depots and shared sites, a lockable cabinet adds access protection.

Best of all, delivery to South Australia is now available. Whether you’re in metropolitan Adelaide, the Riverland, the South East or further afield, our team can quote freight direct to your site. Because we’re the sales division of the manufacturer, you deal factory-direct on price, service and support.

Sizing comes down to three questions. How much do you use per week? How many days of buffer do you want? And what does your site allow?

For example, a mixed farm burning 1,000 litres of diesel weekly might choose a 5,000-litre SmartBund™ for a month of supply. A transport depot may need the full 10,000-litre diesel option. Chemical users can go larger again, with capacities up to 32,000 litres available.

If you’re unsure, talk to our team before you buy. We’ve supplied storage tanks to Australian farms, depots, councils and factories for over 40 years, and we’ll steer you to the right fit — not just the biggest one.

In most commercial situations, yes. EPA SA guidelines call for bunding on stored liquids other than rainwater, and AS1940:2017 sets containment requirements for combustible liquids. A SmartBund™ self-bunded tank has the bund built in, which satisfies this need in many applications without concrete works.

SmartBund™ diesel tanks are available up to 10,000 litres, in line with AS1940:2017. For chemicals and AdBlue, the range extends up to 32,000 litres across eight capacity options.

Yes. Delivery to South Australia is now available across metropolitan Adelaide and regional SA. Contact our team on 1300 826 532 for a freight quote to your site.

SmartBund™ tanks are manufactured from UV-stabilised polyethylene with 110% bund capacity, designed to meet AS1940:2017 requirements for many applications. Your total stored quantity and site conditions determine your exact obligations, so confirm specifics with EPA SA or SafeWork SA for larger installations.

No — each tank should be dedicated to one liquid type. However, the SmartBund™ range covers diesel, AdBlue and a wide variety of chemicals, so you can run matching tanks side by side for different liquids.

On-site fuel and chemical storage saves money, cuts downtime and keeps you on the right side of SA’s environmental rules — provided the containment is right. With SmartBund™ tanks now delivering across South Australia, compliant storage is one phone call away.
