Choose the best tank for your agricultural needs and grow your business manifold.
When it comes to rural households, water security goes beyond personal use. With needs like farming, livestock management, or even off-grid living, water availability becomes one of the most crucial necessities in rural life. In such a case, choosing the correct Water Storage system gains automatic importance.
The right water tank can be chosen based on factors such as water storage capacity, efficiency of the system, tank longevity, as well as your budget. At Premier Water Tanks, we have helped thousands of rural property owners across Victoria make the right choice with custom-built Galvanised Steel Water Tanks.
In this article, we will compare factors such as strength, capacity, lifespan, fire resistance, cost, and others between the Galvanised
Steel and Polyethylene (Poly) water tanks and help you choose the best tank for your needs.
Why is choosing the right tank material crucial?
In vast rural and agricultural regions in Australia’s harsh weather conditions, the reliability of the tank is specifically based on the durability and fire resistance of the tank material. Such conditions also highlight the crucial need for water security. On such matters, all tanks do not perform equally. Hence, a comparison is necessary to figure out which tank material is best and why.
What are Galvanised Steel Water Tanks?
Galvanised Steel Water Tanks are made of high-strength steel, coated with a layer of zinc, which prevents corrosion. At Premier Water Tanks, we also provide an added Food Grade Liner, to make your tank suitable for domestic as well as agricultural use.
Galvanised Steel tanks are built in modular panels and are assembled on-site. This ensures the structural integrity of the tank and secure installation even in remote rural locations where tank transportation is a difficult job. Their capacity ranges from as low as 20,000 litres to over 300,000 litres making them suitable for –
✔ Livestock needs
✔ Irrigation systems
✔ Rainwater harvesting
✔ Firefighting storage
What are Poly Water Tanks?
Poly Water Tanks are built using UV-stabilised polyethylene, which is a high-density plastic. These tanks are moulded in a single piece, making them seamless and lightweight. Being easy to build and install, these tanks come in various shapes, sizes as well as colours.
Due to their limited capacity of not more than 50,000 litres, Poly Tanks are popular in areas where space is limited and water consumption is moderate, like urban houses, gardens or small farms.

Why are Steel Tanks preferred in rural areas?
- Fire Resistance
Rural Australia is bushfire-prone. For a tank to be suitable for such a region, fire safety is an essential feature. Poly tanks often fail under high heat, melting or deforming. This makes them unsuitable to hold water in a situation when it’s highly needed for firefighting. Our Galvanised Steel Tanks can –
✔ Withstand high heat without cracking
✔ Have enough storage to meet emergency firefighting needs
✔ Remain functional even after fire incidents
- High Capacity
Rural regions have high water needs, whether it is for livestock, crop irrigation or daily household needs. Premier Water Tanks offer a capacity of over 300,000 litres, eliminating the need for multiple water tanks and making water shortage a bad dream.
- Long-term water quality
With the food-grade liner, water quality in a galvanised steel tank stays up to the mark for a long time. Free from chemical leaching, cool and clean, that’s how you would find your water inside our tanks.
- Installation Process
In remote or uneven terrain, Poly Tanks can be difficult to transport as they are moulded in one piece. Our Galvanised Steel Tanks come in panel form and are assembled on-site. This ensures that the site is specially prepared for the tank. Such tanks have stable foundations and are long-lasting.
✔ Easy to deliver in uneven and remote regions
✔ Flexible designs to fit certain spaces
✔ Modern equipment to assist assembly, like cranes

What’s right for you?
Both style of tanks have valid applications for individuals with different needs. At certain places, only a certain type of tank can work. You have to define your needs while choosing a tank.
However, broadly, some unique features of each tank make them generally suitable for a particular setting.
- For an urban or suburban household with limited space and modest water needs, a Poly Tank can be a good option as they are aesthetically appealing and have a flexible design.
- For a rural or agricultural setting, a water tank should be high capacity, durable, with strong fire resistance. A Galvanised
steel tank from Premier Water Tanks is best suited for such a household.
Beyond material, you require a supplier that is trusted and is efficient in their job. With over 30 years of experience and positive feedback from our customers, our water tanks can make a serious change to your water system’s efficiency and performance.
