Round Rainwater Tanks

Certified Round Rainwater Tanks, Made to the Highest Industry Standards

Polymaster Round Rainwater Tanks are available throughout Victoria, South Australia, and southern New South Wales. They are manufactured to the highest quality, and are certified to:

  • AS/NZS 4766:2006 Polyethylene storage tanks for water and chemicals,
  • AS/NZS 4020:2002 Australian Standard for drinking water
  • AS 2070 Part 1 and Part 8 Australian Standard for food contact

In December 2008, Polymaster received product certification on all of their rainwater tanks from an independent testing authority. State and federal governments now require rainwater tanks to be certified to Australian Standard AS/NZS 4766:2006 to be eligible to claim water rebates. With a Polymaster round rainwater tank, you can be sure you will be eligible!

Because our round rainwater tanks are made from high quality materials, all round Polymaster certified tanks up to 50,000 litres come with a 20 year warranty (RWT range). Our Poly Choice tanks have a 10 year warranty. All our round rain water tanks feature:

  • One piece construction with no joins, seams or partlines down the walls; and we do NOT remove the top of tanks for transport.
  • Traditional corrugated wall profile cannot be substituted for strength and appearance.
  • Self-supporting roof design has a certified patent and registered design, eliminating the need of a roof support pole.
  • Moulded lugs in the roof of the tank enable easy lifting and can be used as tiedown points.
  • Food grade polyethylene used for all Polymaster rainwater tanks is also fully UV stabilised in all colours.
