Steel rainwater tanks

Store and harvest the rainwater you need

Water Storage Solutions Provided by Puraflo

Regardless of how rainwater is collected, Puraflo has a range of rainwater tanks to suit your collection and storage requirements. In most cases, our wide range of standard sizes will have exactly what you need, but we also can custom build tanks to suit specific requirements outside of these sizes.

Rainwater can be fed to the tank by gravity feed or pumped from your rainwater source collection point(s). This can also be supplemented with the Rainsaver Gutter System, which utilises the tank’s roof area to add to your rainwater collection.

The strength of the galvanised steel panels and the durability and flexibility of the polyethylene lining provide a long lasting water tank with the best maintenance-free corrosion resistance.

Rainsaver Gutter System

Turn the roof of your water tank into a collection device with The Rainsaver gutter system. The Rainsaver is fitted to the perimeter end of the corrugated channels to simply harvest the water running off the roof.

With an average annual rainfall of 500mm, a 11900mm diameter tank could collect around an extra 60,000 litres of water – that’s about 1/4 of the tank!

This gutter system is an option which can be included in the initial install or retrofitted.
