Tasmania is full of cultural icons and landmarks. The Tasmanian Devil, Cradle Mountain National Park, Richmond bridge, exceptional wine and produce… the list goes on. And let’s not forget the good old rainwater tank, as it’s been a staple of many semi-urban and country properties for decades.

Back in the day, a tank was just a tank but nowadays rainwater tanks come in different sizes, styles, shapes, colours, and materials to suit any space. To choose the right water tank that suits your needs, it’s best to know the advantages and disadvantages of the different materials that are being used. These include poly, steel, stainless steel, concrete, and fibreglass, just to name a few. At Orion, we use polyethylene and steel to manufacture our rainwater tanks. We understand the importance of water conservation, Orion Australia manufactures Poly rainwater tanks to suit every situation, be it residential, agricultural, or industrial.

Polyethylene Water Tanks

Polyethylene is one of the most common water tank materials today for many good reasons. Some of the benefits of Orion Poly Water Tanks include:

Bisphenol A (BPA) free: BPA is an industrial chemical used to harden plastics that can cause adverse health issues if ingested. Concerning your protection, we ensure that our Water Tanks made from BPA free polyethylene resins are one of the safest forms of Polyethylene.

Light resistant: Poly water tanks do not allow light into the tank and prevent algae growth; hence the water stays cool and fresh all year round.

UV Stabilised: Manufactured from Australian material, Orion Water Tanks have a double strength UV Stabilisation package for guaranteed performance in the harsh Tasmanian sun.

Fully recyclable Poly: Easy to recycle and replace with a new one at the end of its service life - which for Orion poly water tanks could be over 35 years!

Steel Water Tanks

A well-made steel water tank can be expected to last for decades. At Orion, we manufacture Aquaplate steel & Galvanised steel water tanks that look great, are long-lasting, fully recyclable and bushfire resistant.

Aquaplate is BlueScope steel specifically formulated to use in rainwater tanks and for drinking water storage. We have a broad range of Aquaplate steel rainwater tanks in different sizes, they are proven to be strong and durable which can be a better option in purchasing a steel tank.

Orion galvanized rainwater tanks have a zinc coating to protect the steel from rusting, are fire resistant and provide easy compliance for water storage as required by Tasmania’s BAL assessment protocols. These tanks are extremely strong and suitable for small to very large storage requirements.

Water Tanks are a great addition to any property. They provide water storage in small spaces, such as behind a garage or close to the house. The water is free and can be used for gardening, washing cars, or even drinking, potentially saving hundreds on your yearly water bill. Our tanks are manufactured in Tasmania using only top-quality materials. They are simple and easy to install, strong and durable!

There are so many choices these days, and there are both advantages and disadvantages with any type of material, hence it’s a matter of working out your needs and your budget. If you’re thinking of using the water that is stored in your tank as drinking water, look no further than food-grade materials such as Polyethylene and Aquaplate steel.
