Choosing the Right Tank
Consider your space, roof catchment, rainfall and delivery access before you buy. For narrow blocks, our slimline rainwater tanks sit flat against a wall or fence. For acreage or properties without town water, our large rainwater tanks from 9,000L to 32,000L include free delivery. Contact our team to match a tank to your property.

It depends on your roof catchment, rainfall and water use. As a guide, a garden-and-laundry setup often needs 2,000L to 5,000L, while a household running mostly on tank water usually needs 20,000L or more. For livestock or a rural property, larger is almost always better.
Yes. All our tanks are made from food-grade polyethylene so that they won't taint your water. To keep it clean, fit a leaf strainer, keep gutters and screens clear, and consider a first-flush device. Many households also filter tank water used for drinking.
In many cases, no. Most homes can install an above-ground tank without full approval, provided it meets council rules on size, height and setbacks. Connecting to internal plumbing may require a licensed plumber. Rules vary, so check with your council first.
Built tough, a RapidPlas poly tank will reliably last 20 to 30 years with proper siting and basic maintenance. UV-stabilised RGBlend20 material, seamless construction and 20-point testing help resist the cracking that shortens the life of lesser tanks.
