Large Rainwater Tanks are well suited to rural properties or large town blocks where plenty of water storage is required, especially in combination with a second tank when rainwater is your main supply for household use.
Available throughout most regions across Australia, Polymaster rainwater storage tanks 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
Piece of mind
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
The 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
