Some Fun Facts About The Tank Factory

Having a reliable supply of rainwater is serious business, but that does not mean we cannot share a few interesting facts about our products and history.

How Many Tanks Does Duraplas Manufacture?

Duraplas has manufactured more than 250,000 tanks since 1984. During the April 2025 to April 2026 reporting period, 4,858 tanks were manufactured across the Duraplas product range—an average of more than 90 tanks each week.

With an average tank height of approximately two metres, the total height of more than 250,000 tanks placed one on top of another would exceed 500 kilometres.

Does It Take a Lot of Raw Material to Manufacture a Tank?

Absolutely. Manufacturing thousands of poly tanks requires substantial quantities of virgin-grade polyethylene. The amount of material used for each product is known as its shot weight.

Duraplas uses controlled shot weights designed for each model, helping provide the required wall thickness, rigidity and structural performance. When it comes to dependable storage, material quantity, product design and manufacturing control all matter.

Can I Count on Your Company? What Experience Do You Have?

Duraplas has manufactured tanks since 1984 and remains owned and managed by the founding family. That stability, together with decades of manufacturing and customer-service experience, supports the products, warranties and assistance available through The Tank Factory.

Our experienced team can assist with general product, pricing and delivery information before you place an order and provide support after your tank has been supplied.

You Have a Large Delivery Area. You Must Cover Some Ground?

You better believe it. Delivering large tanks requires careful route planning, suitable vehicles and coordination with customers across extensive service areas.

Our poly tank delivery network covers many areas of NSW and QLD, while steel tank delivery availability depends on the product and postcode. Every delivery also depends on route suitability and safe access to the nominated property.

What Is Our Most Popular Tank Size?

With an extensive range of capacities, styles and colours available, it is a good question. Our most popular model is the Duraplas R22700UR, a 22,700 litre—or 5,000 gallon—round poly water tank.

Its generous storage capacity and excellent value per litre make it a popular choice for homes, farms and rural properties. During peak production periods, Duraplas can manufacture approximately 45 R22700UR tanks each week.

Other top-selling models include our 5,000 litre slimline tank, 3,000 litre slimline tank, 10,000 litre round tank and 2,000 litre slimline tank.

The R22700UR is available in a broad selection of colours, making it easier to choose an option that complements your home, shed or surrounding landscape.

What Is the Most Popular Tank Colour?

Remember when tanks came in only one colour? Our Duraplas round and slimline water tanks are available in more than 20 stylish colour choices, making it easier to select an option that complements your home, shed or surrounding landscape.

Mist Green has consistently been our most popular colour. Its neutral, unobtrusive appearance works well with many Australian homes and rural properties. Wilderness Green follows closely, with Slate Grey, Heritage Green, Charcoal, Smooth Cream and Merino also among our most frequently selected colours.

There is no single right colour for every property. The best choice is the colour that suits your home, shed and surroundings, which is why Duraplas offers such a broad range of options.

A tank should serve you for many years. When ordering a new one, it is important to deal with an established business that can provide clear product information and dependable support.

Duraplas has manufactured quality tank products since 1984 and remains owned and managed by the founding family. Applicable Duraplas round and slimline poly rainwater tanks include a 20-year manufacturer’s warranty, subject to the published terms and correct installation, use and maintenance.

Combine that with New Generation Poly Tank Technology™, competitive pricing and support from our experienced team, and choosing a quality tank from The Tank Factory becomes an easy decision. Contact us today to discuss your requirements.
