Tasmanian Traditional Round Corrugated Rainwater Tanks

In answer to the ever-growing demand for better water conservation technology, Orion Tanks Tasmania have created a comprehensive range of traditional and contemporary styles. We have been making rainwater tanks over 10 years, and the quality of our tanks stand the test of time.

  • Manufactured from food grade UV stabilised polyethylene, which makes them tough, durable and able to stand up to the harsh Australian sun.
  • Our poly tanks do not rust or corrode, and are impact resistant — representing a worthwhile long-term investment.
  • Single piece moulded construction ensures long-term structural strength.
  • Install of all ORION Rainwater Tanks is easy with tap/valve and fit-up kit supplied with every tank.
  • Non-standard fit-up and additional outlet options to suit your particular requirements are available on request.
  • Tanks are available in a wide range of colours, with capacity to match many existing Colorbond® colours.
