Why Choose a Poly Rainwater Tank?

Polyethylene rainwater tanks are a lightweight, UV-stabilised, and corrosion-resistant solution, ideal for harvesting and storing rainwater. Made from food-grade polyethylene, they are safe for drinking water, irrigation, and household use. Unlike metal tanks, poly tanks won’t rust or corrode, making them a low-maintenance and cost-effective choice for Australian conditions.

Poly Tank Options Available

✔ Slimline Poly Tanks – Perfect for narrow spaces, ideal for urban homes, courtyards, and along fences.

✔ Round Poly Tanks – Large high-capacity tanks for maximum water storage, suitable for rural and residential use.

✔ Underground & Under Deck Poly Tanks – Discreet, space-saving storage for compact yards or homes with limited outdoor space.
