Rainwater

Water is the essence of life

At Polymaster we’re working with people, businesses and entire communities to keep our water supply sustainable for everyone.

Together We Hold the Future

View Rainwater Tanks

Polymaster Group’s range of poly rainwater tanks are manufactured and distributed across Victoria, South Australia, and Southern New South Wales.

Due to strict water restrictions across the region, our rainwater tanks are particularly popular on properties in Melbourne and Adelaide and farms throughout Victoria, South Australia, and Riverina in New South Wales. We have a wide variety of sizes and models for all your rain storage needs, as well as accompanying pumps and other accessories. Whatever your property’s size, locale and annual rainfall, we’ve got the right poly water tank for your needs and budget. 

Highest Quality & Standards

All our rainwater storage tanks are manufactured to the highest quality, hold product certification from an independent testing authority, and are certified to the following standards:

  • AS/NZS 4766:2006 P
  • 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
  • Enquire about water tank rebates on your rainwater storage tanks

The Australian government requires your rainwater tanks to be fully certified by the above standards in order for them to be eligible for the rain water tank rebate. This certification is the best guarantee of a long lasting rainwater tank, and means that your tank has been through many strict tests before it is dispatched to ensure it is of highest quality.

From slimline water tanks to round rainwater tanks to underground water storage tanks, Polymaster has all your needs covered.

Why Should You Install a Rainwater Tank?

Using rainwater in and around the home and business is an effective way to conserve precious water supplies, reduce mains water and save the planet. Read the latest news on our blog to learn more.

What Our Clients Say

Just a quick note to thank Leah for all her help with our order of 3 Polymaster tanks. Especially in getting them here today which I know was a stretch but it was really important to get them filled before the January hot weather impacts on our spring. Well done to the whole team and to please pass on our thanks especially to Michael who did a sterling job with getting the tanks into position in 3 different location and driving all the way from Swan Hill today.

Alexandra, Euroa Victoria

Thanks for the great service and providing a quality tank. Ben your truck driver was also a legend in how he delivered the tank - positioning it perfectly for such a large tank.

Carl Fletcher, Victoria

We particularly wanted to compliment your delivery driver Ben for an excellent job. We found him to be immensely obliging and he kept us updated regarding ETC beforehand. Also, he’s incredibly adept at getting his truck positioned and the tanks handled for a perfect landing onto their bases. A first class job, and quite a credit to Polymaster. Please pass on our thanks to him, as well as Emma and all the others who made it happen. We’re a couple of very happy Polymaster customers.
