Dive into the Different Types of Rainwater Harvesting Tank

Slimline water tanks

Perfect for those wanting a tank that looks both appealing and takes little space. Range of sizes for you to choose from and varying water storage capacity

Round water tanks

robust, traditional tanks that are favourite roof-top contenders but can fit any other space on the ground. A popular design with large storage capacity.

Square water tanks

Smaller footprint than the other Slimline or Modline tanks. It will fit in tight spaces and have big water storage capacity. Optimise water in tight spaces.

Modline water tanks

Made for tight spaces, these flat-top tanks still keep the sleek look and appealing characteristics of its buddy the Slimline tank while having a smaller footprint.

Underground water tanks

Like the namesake, they are tanks that go underground out of sight for eg under the driveway or dug into the backyard. Great when you don’t have the space but still want to be water efficient or you want your tank tucked away out of sight. Cheaper than concrete tanks, these are made of polyethylene: light, extra durable and easy to install.

Bladder water tanks

Also known as eco-sac is an innovative, flexible water tanks that can be moved and packed away.

They are typically made from high resistance polyester PVC (Polyvinyl Chloride) or TPU (Thermoplastic Polyurethane)- puncture resistant, high strength material. If space is an issue, then this type of tank may be a better choice for you. It can be placed under houses, decks or buildings.

Correctly installed rainwater tanks will develop a natural treatment train that helps in the cleaning process of the rainwater caught from rooftops catchment areas. This treatment train is the main reason why Australians benefit from rainwater harvesting and users remain healthy and safe.
