About Watersorter Rainwater Tanks
Watersorter Domestic Rainwater Tanks are made from tough, lightweight plastic. Our Rainwater Tanks are moulded in tough food grade polyethylene plastic and exceed the New Zealand standard AS/NZS4766 for upright polyethylene tanks. They won’t crack, fade or rust and their one-piece construction makes them exceptionally strong and easy to clean. They’re also UV-stabilised to withstand the harsh New Zealand sun - perfect for the Nelson and Tasman regions.
