the rainwater tank experts

Welcome to Precision Poly Pty Ltd

Established in 1995, Precision Poly Pty Ltd is a privately owned Rotational moulding company. The company commenced operations manufacturing water and liquid storage tanks.

Precision Poly is a Rotational moulding company which prides itself on producing quality polyethylene rainwater tanks.

Precision Poly Pty Ltd was founded in 1995 by Malcolm Baird. Prior to this he spent 10 years in custom Rotomoulding of industrial products. The wealth of experience he gained in this field enabled him confidently to embark on his own products. The “Slimline” designed by him and in conjunction with a toolmaker uniquely addressed the vast void that existed in the suburban domestic market. Many moulders emulated this original design.

Precision Poly now operates 2 manufacturing plants:-
Head Office at Mulgrave NSW has production equipment consisting of 6 conventional Rotomoulding machines and 1 High Tech Automatic Moulding System.
Burleigh Heads Qld. has production Equipment consisting of 2 conventional Rotomoulding machines.

Support facilities for both plants include laboratory set-ups to verify external and internal quality standards.

Queensland Water Tank RebatesOur nationwide distribution is handled by selected agents.

Most slimline tank manufactures are having difficulties in maintaining a uniform wall section throughout the tank to comply with the published Australian Standard AUS/NZS 4766:2006.In order to meet the minimum wall thickness test they invariably resort to making other parts of the product substantially thicker. This is not an elegant solution. The uneven wall sections precipitate stress cracking and could result in premature failure and warranty claims.


As a customer you are entitled to a trouble free service life. We at Precision Poly proudly warrant our product for a period of 25 years. This is more than double the customary period of 10 years other tank manufactures offer.

Leonardo Water Tank Moulding SystemYou probably ask “How come we can make claims about, thinner and more even wall Leonardo Moulding System product at a lower price than most other suppliers?” One of the key factors is the recent installation of a High Tech Moulding Plant, the only one of its kind in the Southern Hemisphere. This machine is fully automated and computer controlled to verify all important quality data from within the mould while the tank is being moulded. We have taken the approach to treat this project on the basis of “from cradle to tomb “to ensure best practises results at every step of the manufacturing process. This meant we had to collaborate with raw material manufacturers & suppliers of micronised moulding powder to ensure adequate antioxidants levels to prevent the release of carcinogenic substances.

This machine is environmentally friendly. The burners employed to melt the plastic are the latest in low carbon emission design. Compared to conventional burners in use throughout the industry we are experiencing a 61% reduction in carbon dioxide emission. The total energy cost for this plant is reduced by 38%.
This coupled with a 20% reduction in raw material usage per tank has a substantial knock-on effect, resulting in cost savings thus benefiting the economy, the environment and our valued customers.

Whether you purchase your tank to water your garden, wash your car or hook it up to your sprinkler system, we have the tank to meet your needs.

We look forward to partner you in your effort to look after our precious environment.

Our rainwater tanks are environmentally friendly. Furthermore, they are economical as they reduce your water bills.

How much water can you catch?
A simple calculation will determine your potential water catchment.
Every m2 of roof equals 1 litre of water for every 1mm of rain.
Multiply your total m2 of roof area (roof pitch does not alter the amount of catchment) by your annual rainfall average and you will have the total potential catchment for a year. Yes, it is amazing how much water goes down the drain!
Precision Poly has developed a new range of Slimline Rainwater Tanks specifically for installation in residential properties where space is limited.
